Natural Grafts

One of the questions I get about grafting is how in the world did people discover that you could take two different plants and combine their disparate tissues together?  

I think people of old knew grafting was possible because they had seen plant tissues recombine in nature.  Naturalists were outside surveying their environment, and from what they learned from nature, they applied that knowledge to grow plants better.

We have a massive chinquapin oak (Quercus muehlenbergii) in our front yard in Tennessee.  A few years ago, I noticed for the first time in our thirty years of living there that it has a natural graft on the back side.  It is more unusual than most that I’ve seen because three branches come together.

Thread this needle. On the back side of the tree is this natural graft where three branches have become one.

Here’s a side shot. You can see a branch behind curve up and down to merge with the other two branches.

These natural grafts have been known to occur for a long time.  This bulletin from Kew printed in 1917 (over 100 years ago!) describes the process well.  Branches rub off the outer bark in the wind, callus (wound) tissue forms, and eventually the tissues on the two limbs grow and conjoin together.  It is so fascinating to think about the process of how the vascular tissues of large branches can realign and to witness the products of a years-long process.  

This Week in the Garden: Broccoli Ready for Harvest

I returned home from holiday travel to find my broccoli ready to harvest.  I was delighted to see about 15 speckled-blue balloons rising from the forest of glaucous leaves.  

I tried two new cultivars this year—‘Dura-Pak 16’ and ‘Burney’.  These two varieties caught my eye flipping through the Twilley seed catalog because they were listed as part of the Eastern Broccoli Project, an effort to develop broccoli cultivars for the eastern and southern US that tolerate our warmer nights, have flatter heads to shed rain, and root systems that are more tolerant of wet soils.

It was certainly a good year to evaluate their adaptability to wetness.   Greg Grant posted online the other day we’ve gotten 82 inches of rain this past year.  Just since September 1, 45 inches have fallen!  That explains why I’ve had a creek running through my yard since October.  

The plugs also got into the ground a little late, but it’s not uncommon for me to be harvesting broccoli in December and January.  Now, I’m curious to see how these types do on the other end of the cool-season spectrum.  We shall see come later this spring.  

One of my favorite ways to cook broccoli is a recipe learned from Alton Brown’s Good Eats.  Wash it well.  Quarter the florets and stems.  Put it in a skillet with about a 1/4 cup of water.  Turn the heat on high for three minutes and then low for three minutes.  Add some butter and salt, and you’re good to go.  

The buds of ‘Dura-Pak 16’ are quite tight.

‘Burney’ buds are getting a little large, but they’re still delicious for eating.

Students Showcase an Interest in Horticulture

This weekend, it was my turn to help out with Showcase Saturday, an opportunity for high school students considering SFA to come check out our school’s diversity of majors. When I’ve assisted in the past, we have at most two or three students come up to our agriculture department booth and ask questions about our horticulture program. I expected the same turnout.

But, by the time I left, we had TEN students who had came by and expressed interest in horticulture. I was amazed. From the time the event started at 1:30, I felt like I was talking to students for 45 minutes straight. One student had even come six hours from Oklahoma with her parents because she heard that our program was really good, and she was looking at it over other programs near her home! (In full disclosure, they were headed to her grandparents who lived about an hour away, but still! I was impressed!)

They came with questions about our program, what we offered and how we were different from other universities, and what career opportunities were available after graduation. Not all of them knew the word horticulture. Some came saying they were interested in growing plants or hydroponics.

After my amazement wore off from the constant stream of students interested in growing plants, my analytic scientist brain switched on, and I started asking questions such as how did you even hear about horticulture, a word that normally has low recognition amongst youngsters. The common thread was high school opportunities—classes for horticulture and/or participating in floral design or nursery competitions in FFA. These comments helped to support a trend I’ve seen of more and more high schools offering horticulture classes and doing greenhouse projects. (Even mine back in Tennessee built a greenhouse right after I left!) I would like to see some hard data, but I think there’s something there.

Time will tell if they actually decide on horticulture as a major, but the students’ comments reminded me of what I’ve been preaching. For people to engage with horticulture and plants, they have to come into contact and imbibe the wonder of plants or else this potential passion in many students may lie dormant.

Yes, we have to accept not every seed is viable. Even Aldo Leopold realized, “There are some who can live without wild things and some who cannot.” I believe the same dichotomy applies to encouraging an interest in plants and even pursuing a career in horticulture. But, visiting with the students this weekend reminded me we must be present and keep reaching out to those that love the wild green things in anyway that we can, even if their love hasn’t germinated yet. It did in me, it did in you, and it will in them.

Magnolia Seed, Spooky Stuff

“Have these things always looked like this?,” Karen asked with a hint of surprise in her voice.

Even though my back was turned as I stood at the kitchen sink, I knew exactly what had caught her eye.

A few days earlier I had plucked some ripe fruit from a Magnolia grandiflora in our yard that had colored up very nicely. They were easy to find on the ground and in the tree with their blushed, knobby appearance. I brought them indoors and was inspired to put them in a bowl on our table from seeing them top containers a few autumns ago at the Scott Arboretum. Such a clever use!

When I brought them inside, the fruiting bodies were sealed shut, but a few days in the house and the follicles on the aggregate structure started to split open and reveal their vermillion-colored seeds inside.

“They look like painted witch fingernails growing out of these things,” Karen continued. Both she and her sister who was visiting from out of town indicated they looked a bit freaky. It was nearing Halloween, and we had just watched Hocus Pocus a few nights earlier. I could see how seeds that magically appear overnight growing out of a structure could be a bit spooky and repulsive.

I, however, was delighted to see the seeds. We want more Magnolia trees on our property. Most years I’m too late getting to a tree to collect the little rubies because the birds and mammals get to the goods first. But, the propagules were right on my table for the picking.

In prepping for sowing in the past, I’ve removed the outer aril scrapping them with my own fingernails. However, one of the tricks I learned from reading Andrew Bunting’s book The Plant Lover’s Guide to Magnolias and a blog post he wrote during his tenure at the Scott Arboretum is soaking the seeds for three days in water will aid in removing the red arils that cover the surface along with any associated eeriness one might perceive.

Tonight, I plucked the last of the seeds from the follicles and plopped them into water-filled mason jars on our kitchen windowsill. After they’re cleaned, I’ll sow them in some damp growing media in a ziplock bag, stick it in the fridge for a couple of months to help overcome dormancy, and sow them in late winter.

I just hope no one confuses this batch in our fridge for chocolate cake mix.

The Old Factories

The door has closed for good on the old factory. Once full of the hustle and bustle of making, the air inside is now still and quiet. The essentials were moved out and relocated. All that’s left is a lifeless skeleton.

And, then the factory falls. From some lofty branch, this once photosynthetic powerhouse takes a whimsical whirl to the ground. Its landing spot is as uncertain as is its future.

Many view these factories with scorn. They burn them, demolish them, toss them to the curb. Anything to make the abandoned structures vanish and keep up the block.

But, I enjoy the old factories.

I enjoy shuffling through their midst. Their stark colors pop against the verdant turf. In some, the incandescent glow hasn’t been turned off just yet and still beam of color from livelier days. Where the wind takes them, they congregate and delineate fencerow and field alike. In such piles, kicking their stolid walls in a stiff breeze animates them once more.

I also enjoy how the old factories enhance the neighborhood. Arthropod entrepreneurs move in and bring a second life to these empty vessels. These remnants become hangout places for fungi and fun girl alike. Soon, the smell of brewed geosmin and earthy smells is on every corner. Graffiti and murals from earthworms and beetles appear overnight. Gentrification, right out my back door.

Yes, I enjoy the old factories. And, I wouldn’t get rid of them for the world.

With the arrival of November, I find myself raking leaves. And, being surrounded by trees on two and a half acres, we have plenty to use. Some have started to drop in earnest while others still hold fast. The succession helps this collector of fallen foliage.

While many gardeners herd them to the curb, to me each leaf is precious and nary a one leaves our property. For years, I’ve considered the litter quite valuable. Even as a teenager, I’d pile them up to make leaf mold and use this black gold to mulch plants the following year.

I keep my greed in check. Many that fall lie where they land for most of the winter. But, in areas where they are plentiful, I relocate them by the wheelbarrow load from the lawn to garden beds. A thin layer keeps the weeds down around vegetables, perennials, and woodies, and a thick layer smoothers the grass (save for the dastardly Bermuda!) to help create new planting areas. That’s exactly what I’m doing around our fig saplings. In the spring, this blanket will be plugged with grasses to create a groundcover matrix.

Some beds that I mulched last fall still have an icing of last year’s leaves. Amazing, no? They need a new coating as a few weeds are gaining hold, but still I’m impressed that they’ve persisted for so long.

Yes, I wouldn’t get rid of them for the world.

I'm Digging Peanuts

I dug peanuts the other night for the first time ever. I did the math and determined that approximately 130 days had passed since I shelled the seeds and thumbed them into the ground. Still wanting to garden after the sundown in a month of shortening days, I decided their time had come. I turned on our side door lights, grabbed the pitchfork, and stepped off into our kitchen garden to start prying them up.

We don't have very many plants in the ground—maybe 30–40 in a bed ten feet long. I was wanting to trial them out here in east Texas before I went gung-ho planting. With this small space, I didn’t expect the harvest to take too long or be too difficult.

The only hindrance was finding where a plant’s crown was. It wasn’t the dark that hid them but the long shoots. 'African Runner' was really living up to its name as shoots two feet or longer weaved together to form an amorphous mass of foliage.

A few pries from the fork along the edge, and they slipped right out of the ground with a gentle tug. I was surprised to see the peanuts holding onto the plant so well from the little pedicles. Having just dug sweet potatoes a few weeks back, I figured they’d be breaking off left and right to escape the harvest and remain in their underground sanctuary.

After digging, I laid them upside down to let the plants wilt a bit and called it a night. A rain the next day washed most of the soil off and made removing the chthonic fruit from the plant a much cleaner job. Karen even helped a bit, and by the end of sorting through the legumes, we had over a gallon bucket’s worth. Plenty for next year, Pad Thai, roasting and salting, and maybe even some peanut brittle if I’m adventurous.

Peanuts galore.

Overall, I was quite pleased with their performance. They made a spectacular groundcover during our fierce summer; therefore, I’m considering integrating them with summer crops like sunflowers and corn. Get the taller plant growing and then come behind with peanuts. Their nitrogen fixing ability is a plus as I explore using more functional cover crops here.

A Sweet Harvest

My first job was working two summers during high school at a sweet potato farm just over the county line in McConnell, Tennessee.  Mom got me the gig.  Fred’s Plant Farm was owned by one of her co-workers, and he was looking for weekend and summer help.  Every Saturday morning till I got my license Mom drove me to work.  It was hot work, but as I reflect on those sultry days, I have fond pastoral memories of working on a farm. 

The plant farm's claim to fame was once having their sweet potatoes mentioned on the Martha Stewart show.  It wasn’t the large storage roots we dug each fall that Martha had mentioned.  No, what she had purchased were sweet potato slips, short adventitious shoots that arise from the storage root.  These were the mainstay of the company and easily shipped across the country to tv mogul and master gardener alike.  Selling large sweet potato roots in rickety wooden bushel baskets was just a bonus.

Before I arrived, I knew very little about this root vegetable that thrives in our southeast weather.  At the time, I didn’t even like sweet potatoes.  But working on the farm gave me a great crash course of how to cultivate this southern staple.  To produce the slips, we erected wooden beds about 10 feet wide and 100 feet long initially in a hoop house and then built them outdoors once it warmed enough to pass the fear of freezes.  We leveled the soil, poured the sweet potatoes in by the bushel, and then topped them off with four inches of fresh sawdust.  As the sawdust heated, it nudged them along into sprouting. 

Sweet potato slips grown in a bed of sawdust. The propagules are pulled, bundled, and shipped around the country.

We waited I don’t know how many weeks for the shoots to emerge in the cool spring.  I was so eager to see the little tops push out of the substrate I dreamed one night that I walked into the hoophouse and discovered hundreds of them sprouting.  The next day at work, lo and behold I found some emerging.  After they appeared was when the real work began. We would spend hours pulling sweet potatoes in bundles of 50.  These would be packaged and shipped off.  The last of the batch would become our starts for the fields.  Once planted, they grew until harvested in autumn and then were stored over winter until the whole process would repeat again the following spring.

---

Ten years later, I’m growing sweet potatoes again.  But, now I LOVE LOVE LOVE these sweet and nutritious delicacies:  sliced and diced with cajun seasoning, mashed with butter and salt, or in sweet potato casserole (or as my friend Stewart Thomas calls the dish butter and brown sugar casserole with a bit of sweet potatoes).  The casserole was what converted me.  A recipe my mom found won 1st place at a cooking contest in Tennessee, and it didn’t rely on any of that extra marshmallow or raisin fluff. 

As much as I love them, it can be hard to find slips every year to purchase, and sometimes they can be quite expensive.  Sweet potatoes are an asexually propagated crop.  Most organs that we store as vegetative propagules like sweet potatoes, Irish potatoes (which is a swollen stem, not a root), garlic (which are swollen leaves, not a root), and the like we don’t store as seed.  These fleshy organs are still metabolically active whereas many seed are dormant or in a resting state just waiting on water.  Therefore, they won’t keep as long as say those tomato seeds from five years ago in the back of your fridge.  That’s why they must be constantly regenerated.  Hence the need to go slip to root to slip. 

To get slips I took a lesson from my farm experiences as a teenager, and I grow my own.  First, I propagated a few at SFA and watched students enjoy learning how to start the little slivers.  I got my starts for school a few summers ago from George’s Plant Farm in Martin, TN.  Funny that the one place I could find several different varieties available in the whole country was only about 30 minutes from my Tennessee home.  We planted them out, and the following fall my Fruit and Vegetable Production class harvested over 90 lbs of sweet potatoes.  We averaged 1.6 lbs for ‘Beauregard’ and 0.6 lbs for ‘Purple Passion’.

A sweet potato slip grown by a student at SFA. Probably named so because they slip right out of the substrate with a nice jerk from above.

After harvest, I had the students grade the sweet potatoes into large and small roots just like we did back at the farm.    The large ones we sold in our garden market, and the small ones we stored in our classroom for forcing later in the spring.  When time came the next year, we used four-inch-deep nursery trays to start our slips.  We covered them with potting substrate, placed the trays in the greenhouse, and less than a month later the shoots were ready to pull.  If left too long, you could quickly see where the genus gets the name Ipomoea, which means worm-like.  The shoots will grow and wriggle all over the table even from the little bit of soil in the tray.  

Once slips are pulled, a quick jab and pry forward and back with a sturdy shovel makes a good planting hole.  We stick the shoots in, and they form roots very quickly.  Well, let’s be technical.  The latent roots already in the stem emerge quickly.  That’s right, sweet potato stems have roots up and down their length as does tomatoes, coleus, and willow that enable them to quickly gain purchase to new soil or if damage occurs to the stem.  Cuttings I’ve taken in the past put out roots within two days in water.

This year at my house, I’ve played around with making starts, too.  I took some leftover ‘Beauregard’ and ‘O’Henry’ sweet potatoes we purchased, nestled them just under the soil, covered them with a few inches of leaf mold, and less than two weeks later I saw wee little shoots poking out.  After they got a few leaves on them, I pulled them out of the ground, and stuck them into a bed.  They’ve grown beautifully over the summer excluded from deer by our double fence that surrounds our patch. 

Sweet potatoes are excellent soil covers as you can see in the image above. If you can keep them clean early on, they will seal their canopy and prevent weeds from germinating. However, I left the Rhus seedling in the back right corner to be moved to our prairie.

This past week marked approximately 100 days since planting, and the fresh rains that have fallen loosened the soil.  Time to dig sweet potatoes!  I cut the foliage off and carried it to the compost pile.  Then, with the pitchfork I jabbed straight down into the ground careful not to puncture the storage roots, pried the swollen treasure out, and moved down the bed to unearth more.  After all were dug, I gave them a light rinse from the hose but not a scrub.  You don’t want to remove too much protective waxes from the root.  Now, they have been sitting outside for a week elevated to protect from hungry rodents.  This practice helps the wounds heal over.  In the next day or so, I’ll move them inside.  The small ones I’ll keep for next year, and the big ones I’ll eat.  

Thar she blows! You know you’ve got something under the ground when you see the soil around the stem bulged up.

The swollen roots of ‘O’Henry’ sweet potato. Getting them out all still attached to the plant is an art in produce transportation.

My table runneth over with sweet potatoes. ‘Beauregard’ on the left and ‘O’Henry’ on the right.

And, oh will I eat them!  I’m ecstatic about our harvest this year.  ‘Beauregard’ is an old favorite of mine so I’m thrilled to have a good supply of this orange fleshed variety, and ‘O’Henry’ is supposedly a white-fleshed mutation of ‘Beauregard’.  It’s yield was about 50% more than the ol’ Beau.  So, if it tastes as good, I may have found another favorite variety.

One final note as far as cooking goes.  You can enhance the sweetness of them by starting them in a cool oven.  The enzyme that converts starch to sugar has more time to act if you start them cold than if you pre-heat the oven.  Cause if you’re going to grow sweet potatoes, why not make them as sweet as can be?    

Bolting to Boltonia

I’ve been on a Boltonia kick of late.   

It started because of how well Boltonia asteroides has grown for me this year.  I’ve wanted to try this species for a while because BONAP showed its range extending down into Louisiana, and I thought it might do well in east Texas.  On a trip to North Carolina several months ago, I picked up a plant labeled Boltonia asteroides ‘Snowbank’.  It was just scrawny leaves in a 4 inch pot when I bought it.  I stuck it in a trial bed that received very little moisture over the summer and didn’t expect much from it.

But, the doll’s daisy kept growing and growing and growing.  Till it was over my head.  That was even after the top was nipped out by deer.  Althought it was labeled as ‘Snowbank’, I actually think that I got the straight species instead.  ‘Snowbank’ tends to be shorter.  The height isn’t a bad thing and allows me to look up into a cosmos of thousands of flowers, each swirled with white rays and a glowing yellow disk at the center.  

Boltonia bokeh.

Close up of Boltonia asteroides flowers. Once they begin to fade, the ray florets rain down and cover the ground like little white sprinkles. Or, your arm if you brush past the plant.

This Boltonia asteroides is over six feet tall in my little trial bed beside our house.

On mornings following a rain, the thin stems are bejeweled in droplets of water that shimmer in the rising sunlight.  The foliage is a glaucous color, and this dusting of blue-gray provides the slightest color echo for the white ray florets.  And, if you pull on the margins of the leaves, you’ll notice a sharp edge from the little cilia.  So much character from a native.  

Armitage’s tome says that "most species are too large and lanky to be considered for anything but the wildflower garden."  Bah.  I think there’s an elegance to the plant, and I agree with Allan Lacy’s account in The Garden in Autumn where he admires the “delicacy and substantial presence” of Boltonia.   And, let’s be honest.  The wildflower look is quite what I’m after.  Maybe it’s not as lanky because we are so dry here in east Texas?  Time will tell.  My only concern growing it is I’ve read if it’s happy it can spread via rhizomes underground.  So, I’m going to find somewhere it can grow where that won’t be a problem. I’m already eyeing our fencerow.

---

Around this same time that I was being enchanted by my Boltonia blooming, my friend Patrick Cullina posted a picture of Boltonia diffusa at the Atlanta Botanic Garden on Instagram.  Same effect, but only a third of the height!  Wowzers.  I went back to BONAP and was delighted to discover it’s native to our area!  My mind started drifting back to last fall when in the post-house buying haze and rush I wondered if I had caught a glimpse of this species in our area, perhaps even on our road.  I reached out to a few local colleagues who said they had seen it scattered on county roadsides and ditches.

A day or two later, a flurry of white flowers caught my eye on the side of the road, and one evening when I had some time I stopped to investigate, I found smallhead doll’s daisy.  The flowers and foliage were just like Boltonia asteroides, only smaller.   It had been nipped a while back, and inflorescences arose from around the pruned point.  The cut was probably from the mowers when they came through in August. 

Boltonia diffusa growing in the wild.

Boltonia diffusa settles into its new home in our garden. Blooming at just over a foot tall, I see it making a great companion plant to weave through accent grasses and taller forbs.

A second patch I found was much larger. It seems these two were early to come into bloom.  With a mental image of this dwarf doll’s daisy, it seems every quarter mile driving into town I’ve started seeing little clumps of the blue-green foliage waiting to be adorned with autumnal flowers.

I collected pieces of the two clumps I found and planted them back at our house to start bulking up for our prairie here.  I don’t think it will be hard to propagate.  The rhizomatous nature was evident from the off-white shoots I found underground. 

Whether these doll’s daisies are tall or short, I’m happy to have them in our garden.   I’ve still got ‘Snowbank’ on my wish list, and diving into Lacy’s book on autumn alerted me to ‘Pink Beauty’, a pink-flowering form from Montrose Nursery.  Looks like I’m not done growing this genus.  

Eragrostis, a Grass I Love

One of the perks about living out in the country is I have a delightful 20 minute drive into town to enjoy the east Texas countryside and keep abreast of the phenology of the local flora. 

It was about this time last year right after moving into our new house that I was driving to work familiarizing myself with my new route when a plant sporting a glimmering haze on the side of the road caught my eye.  When I actually had a chance to stop, I pulled off and identified it as Eragrostis spectabilis, commonly known as purple love grass.  I enjoyed seeing the dew collecting on the panicles and the early morning light imbuing it with an ethereal character that would inevitably evaporate as the day aged.  Most sprigs I saw were single, scraggly flowers that looked like the way a young girl might practice putting her hair up for the first time. 

But, one clump was spectacular!  It was full and lush, bigger than a basketball, and hard to miss in the fresh light of dawn.  Every day I’d drive past it and admire that shimering plant against a shaggy fencerow.

I had to have it.  Since I arrived in Texas in July of 2014, I’ve been hunting for short, groundcover species that will perform well in our area.  Most plants I’ve tried are imports, but here was a species right down the road just waiting to have its potential realized.  Being September, I knew that there was a chance it might not survive as many grasses moved in the fall don’t establish well.  But, with love and care and some horticultural knowledge, there was also a good chance it would live.  

With shovel in car one Saturday morning, I pulled off along the roadside and walked over to meet my new friend that I had been admiring from afar.  The spade slid right through the sandy soil, and a few jabs and levers later the Eragrostis was up with a nice rootball still intact.   Any guilt I had collecting the wild vanished a few weeks later when the mowing crews came along and sheared the roadsides.  

Back home, I found a nice spot for the transplant in the catch-all herb bed of our newly formed kitchen garden.  There, I could check on it every day and water it as needed.  I was thrilled when I saw little discoloration the next few days from it adjusting to being moved.  A few blades turned tan and purple, but overall the plant settled in nicely.  

Even though it had a few bruises and browning after being transplanted from the roadside, this mother plant of Eragrostis has settled in just fine.  You can see the speckled haze of flowers hovering above the foliage.  

I loved going out in the mornings and see my new Poaceae pal wrapped in a crystal veil.  The flower color is not as purple/pink as most of the examples I’ve seen in catalogs or online, which made me question it's identity.  But, the height is right, it has knobby rhizomes, and the flowers match what I can find in dichotomous key photos.  My guess is down south the color is weaker than our northern counterparts as is the case for many other ornamental plants in our sweltering heat.  Or, perhaps this southern ecotype sports inflorescences that are a lighter shade of maroon?  I tried another strain of Eragrostis spectabilis from further east a few years ago whose flowers were more pink in color, but our little trial of plants died.  Perhaps they were in too wet a spot in too wet a summer?  Or, maybe it wasn’t locally adapted yet?  Not sure, but this one I discovered has performed beautifully. 

The typical rosy-colored flowers of Eragrostis spectabilis.  

The clump I found and those that I've propagated have more of a light pink or tawny color in the inflorescence.  

As September wore on, the panicles started to mature.  I collected some seed, and sowed them on a whim.  To my amazement, they started germinating within just a few days!  No stratification or even dry storage required.  For those that need a review from plant propagation, dry storage is the name of the germination delay that some seeds experience to prevent them from germinating too early or on the mother plant.

Once the seedlings got some size to them, I took them to school and had a student pot these few up into a couple trays for our school garden beds.  To my amazement, the disturbance in the pot caused even more to germinate!  It seemed to good to be true.  These little sprigs I brought home and planted into beds here at the house.  As more of the original plant’s inflorescences began to mature, I collected more seed to become the stock for our plantings on campus.  

Winter came with the worry of loosing the original clump, but this spring, I was thrilled to see new shoots emerging on the mother plant.  Being a C4 grass, it was slow to get going, but when the brunt of summer arrived it erupted into growth.  Eventually, I tried my hand at dividing the clump into about 20 propagules, and the majority of these survived.  However, divisions do seem to grow a bit slower than those from seed.  I was also delighted to discover a few offspring popping up around the mother plant.  One even sowed its way into a crack in our pavement.  

Now, a year has passed.  We have hundreds that have been planted around the SFA agriculture building.  And, back home a few that I transplanted carpet the ground in a portion of our herb garden.  I’ve also planted it as the groundcover layer in the beds on the eastern half of the swale I’ve been building through our kitchen garden (more on that in a later post).  What few perennials I plugged around these starts look like ship masts emerging out of a grass fog.  The effect is similar to muhly grass (Muhlenbergia sp.), but the height is shorter.  It would occupy more ground, but I ran out of plants here at the house and have to propagate more.  No worries as it appears I’ll have thousands and thousands of seed in a month and Heaven knows how many seedlings next spring.

En masse this Eragrostis is spectacular, especially when covered with morning dew.  Here, it is planted along the swale that runs through our edible patch.  Next year, I expect more perennials to be established and piercing the floriferous fog.  

I feel proud having moved it—perhaps I could go as far as saying saved it?  And, I feel that joy every time I walk past the clumps.  In the morning, strolling past the wet panicles reminds me of the plant perspiration Christopher Lloyd wrote about in Exotic Planting for Adventurous Gardeners.  And, once the dampness vanishes, the flowers brush against your leg like a friendly feline. 

This ecotype of Eragrostis will become a permanent fixture in our prairie plantings here at the house and on campus.  And, why not?  With a plant named love grass from right down the road that thrives in our climate, what’s not to love?

A Prairie from Scratch

Ah, August.  With the arrival of midsummer in the deep south, we can actually garden again without just hauling water to and fro.  Fall seeds are arriving, new growth is starting to appear on sun-scorched plants following a few afternoon showers, and my mind is dwelling on upcoming garden projects.  Forefront on my list is a prairie.

When we bought our house almost a year ago to the day, one of the acts that excited me the most was the creation of a prairie.  But, why?  Why return a 1/8th acre of clipped turf to wild?  These are a few reasons that immediately came to mind.  

1. As I’ve written before, I love grasslands.  Call it primal or call it high culture, but a waltz amongst the panicles and the floral tapestry of the wild is enchanting.  

2. I want to learn.  I want to get a hands-on education in making designed plant communities in the southeast.  This planting will become a living lab to practice different designs, combinations, and approaches.  Can I really plant directly into turf?  How can I achieve color or interest every week of the year in east Texas?  What will be a thug, and what worthwhile will need encouragement?

3. A prairie will reflect the genius of the place.  Drive down our roads, and you see Liatris, Asclepias, Vernonia, Rudbeckia, Baptisia, Gaillardia, Delphinium, Hymenopappus, Echinacea, Callirhoe, Penstemon, and more all growing in a matrix of short grasses.  Why not concentrate this wild and have it right out my door?    

4. I love seeing the wildlife flit and flirt across our micro-farm. It takes me back to my childhood chasing frogs at sunset or the first chrysalis I ever discovered.  Creating habitat for fauna of all kinds makes me feel like I’m doing good in this world, and as Noel Kingsbury recently argued is a core element of the designed plant community concept.  

5. Karen wants a prairie, too.  (No, really!)  I realized I've made her a bit of a mulch snob when she comments on far apart spaced plants and the wasted space between. 

My mind has iterated through different locations on the property.  At first, I wanted the planting to be in our backyard surrounding a towering water oak, mainly because early on we were spending hours on our backporch.  But, with time living here, I eventually realized that to the west of our house beside our driveway would be the best location.  The spot is a beeline straight from our kitchen window, and standing at the sink I find myself gazing out and imagining what will be in bloom or seed.  The site gets full sun save for the last few waning hours of the day when shade is cast by a mature water oak and a teenage Taxodium.  The site slopes slightly to the west in a terrace-like fashion, and the lay of the land is perfect for catching morning light as the sun lifts above the distant thicket in the summer and the house later in the winter.  Also, the prairie will be visible from the road so that people will see the crazy things that plant doctor is doing.  

The space is rectangular and runs the western length of our driveway.  It’s about three times as long as it is wide, tapering a bit with the curve of the asphalt.  The length of the prairie warrants a vista, and I know I want to frame the view and have something at the north end draw one’s eye from the south where the road is.  Our edible patch is just beyond the prairie, and perhaps I can create a focal point near this space.  Not sure what yet though.  

The biggest question I’ve wrestled with this spring and summer is how to create an immersive experience in the prairie.  How do I design it to be tangible and imbibed?  Paths are the obvious answer and will allow the interaction with the plants from a variety of angles.  I considered different layouts including parallel lines, turf spaces that ebb and flow in size surrounding a sea of taller foliage, and even doing geometric shapes like the orchard plantings at Le Jardin Plume.  Finally, I decided on a curving path that winds through the area and eventually circles back on itself.  When the grass is tall, I envision curves hiding what’s next and creating a sense of mystery.  I’ve also envisioned resting spots along the path throughout the prairie made by circles where chairs and tables will allow one to stop and enjoy the creation.  

Like a light pencil on a blank canvas tracing guides for a greater work of art, I’ve used my riding mower to mow lines for various projects at our house to begin shaping spaces, and I’ve used the same approach with our prairie.  Yes, it probably sounds like hillbilly horticulture, but it works.  I set the mower blade a bit shorter than the rest of the grass and mow the lines I want.  Any errors of my ways will grow back.  Living out in the country affords me the opportunity to play around in ways in which a city dweller might receive a citation or gawks.  With the prairie, I mowed the path I had in mind.  I walked the length of it stopping and pausing to view certain perspectives and to see what I liked or didn't.  Then, the outline is there for several days to allow the mind to absorb, mellow, and consider different scenarios.  After a couple of runs, I’ve about got the path where I want it.  To create resting spots in the prairie, I stop along the path with the mower and start circling outwards till I feel the space is large enough.  Eventually, I will put a peg in the center and measure a circle with string.  

Just some scribblings.  So that you could better see the paths and resting areas that I mowed, I colored them in on my iPad.  This view is looking north toward our fenced in edible patch, and you can see how the length beckons for shorter plants that will create a nice vista over the prairie.  

To give the planting legibility, I will keep the turf next to the drive way.  Two mower passes from the drive gives me a swath about 8–10 feet wide .    This area will also allow people space to park along our drive when we have several visitors.  

The side of the prairie that runs along our western property line will be planted with woody species, mostly evergreens to complement the Quercus and Taxodium already there.  We’ve known we wanted a privacy wall since we moved, and the verdant height will serve as a foundation that will help the front flora pop.  A lone Magnolia grandiflora ‘Bracken’s Brown Beauty’ is the start of more to come.  

The other woody species I want to add will help to further frame the prairie.  On the north and south ends, I want to plant fruit tree species to create an edge habitat, the height and spacing of which will quickly taper to a full sun planting in the center of the garden.  The north will get a mostly full circle of hybrid Asian/American persimmons I’m dying to try here in east Texas around one of the resting spots I mentioned earlier, and the south will get a groove of pawpaws.  

The other big question that I’m pondering is should the turf stay or should it go?  When Thomas Rainer spoke for us back in April, I showed him the area to be planted, and he asked me if I was going to plant directly into the grass and let the forbs and taller grasses take hold.  I told him I didn’t know, and I have since ruminated on that question.  I’d like to kill off everything because that gives me a clean slate.  But, the turf is dominated by centipede grass with some dreaded Bermuda scattered about.  That spawn of Satan I will be killing.  But, the centipede may act as a great groundcover to allow the transplants to get established and prevent various weeds from germinating.  

I’m saving the rest of the plant list for another post.  The cast of characters is still a work in progress and will likely be for the life of the planting.  I will say that the garden will be planted in phases, and I've already identified the north end as the first phase.  I’m in no hurry.  I’m propagating species here either by division of plants that I buy or find in the wild or from germinating and growing seed.  

In closing, I'll say all good prairies need a name.  I’ve chastened this area Prairie Lark, a play on words of one of my favorite avian species, the Eastern Meadowlark.  And, besides describing a passerine, lark also means "a source of or quest for amusement or adventure” and “to engage in harmless fun or mischief”.  

It's a perfect word for creating a prairie from scratch—an adventure with a little bit of fun and mischief mixed in.
