Solstice Seedlings

We are a a little over a week away from the winter solstice. The year has wrung about as much light out of the day as it can, and we have mere minutes left to lose until we hit the shortest day of 2022.

It’s in this solstice season that I start planning in earnest for next year. With the semester over, the growing season ended, and the new year on the horizon I have time to consider the goals and projects I want to move forward in the coming year.

The plants in my garden are preparing for next year, especially those whose growth culminates in spring. Even though March is months away, amongst the duff there are hints of the next growing season starting to appear. Every day harnessing the sun counts in the march toward warmer weather for making sugars that will become more blades and blooms.

I’ve spied the lobed foliage of Delphinium carolinianum (prairie larkspur) and Viola pedata (birds-foot violet) in the garden. The maroon leaves of Claytonia virginica (spring beauty) no longer hide amongst the tawny, frosted turf. I even found two with open flowers in our backyard this week. The little toothpick leaves of Phlox pilosa (prairie phlox) are emerging. And, the first of my perennial sowings from this year are germinating.  

Late last spring, I sowed Marshallia caespitosa (Barbara’s buttons) and Callirhoe alcaeoides (white poppy mallow) from seed collected in my garden.  I love both for their white flowers and desired more as they are good fillers for spring color. Callirhoe has this ability to thread itself through the matrix of foliage, and looking down on a Marshallia is like looking up at a galaxy. Both go dormant in my garden soon after they flower and set seed.

I decided instead of letting the progeny sit in storage in the fridge, I would promptly sow them and put them on my small nursery pad where they would receive occasional irrigation over the summer. Often with the first time sowing a batch of seed, I will sprinkle them on potting substrate in a gallon pot, trust mother nature, and watch and learn for next time. Both seem quite happy with this approach thus far.

Even though they got water all summer long, their emergence coincided with the return of cooler weather this autumn. Like many native perennial seeds, the delay makes sense to wait and start growth when conditions are more appropriate. The Callirhoe germinated fast while the Marshallia were more staggered.

Towards spring I’ll tease them apart and pot on into trays to allow each plant to have space to grow.  And, then once they’ve bulked up a bit, I’ll welcome these plants into the garden.

I suppose in retrospect my planning for 2023 started earlier in the year than just here at the end. Every seed I sowed in anticipation of having more plants for next year is hope and planning for greater things to come. Their appearance is yet another thing to celebrate in this solstice season.

Thankful for the Return of Snowdrops

“YES!” I exclaimed! “They came back!”  Before me was the cupped blade of a single snowdrop piercing up from the soil.  I scraped some leaves back and found more shoots.  “And, another!  And, another!” I added. 

It was early November, and I was so ecstatic. I have been searching for bulbs to grow in east Texas outside of those that have a reputation for thriving here. Autumn-flowering geophytes that don’t need significant winter chilling to flower I felt held promise as our lack of vernalization is the limiting factor for many species. Galanthus elwesii var. monostictus (one-spotted greater snowdrop) was high on my list to try. 

My introduction to this late autumn flower was from visiting Nancy Godwin at Montrose Gardens in Hillsborough, NC. She turned a handful of bulbs years ago into thousands of plants that now carpet the understory behind her homeI have multiple memories of visiting Montrose around Thanksgiving for one of her snowdrop walks with friends. And, now mine were blooming right on cue.

I had bought some bulbs from Nancy before and tried them in a container thinking that the soil here might be too dry, but I lost them twice.  I figured third time was the charm, and I acquired more bulbs in the green from Nancy last winter.  I decided to be brave and try them in two in-the-ground locations; both spots I amended with grit and lime to improve the soil conditions.

I planted a few in my fenced in patch where they would be protected from uprooting armadillos and able to get more water during the summer when I irrigated summer cut flowers and veggies.  Years ago, I read in Scott Ogden’s Garden Bulbs for the South that most Galanthus should not dry out during the summer and often like wetter spots. 

However, Nancy told me that where she has these autumn-flowering snowdrops in her woods turns bone dry in the summer. Therefore, site two was higher and drier underneath trees in a new bed that magically appeared after we lost some azaleas in the freeze of February 2021. I didn’t water this site all summer.

This shaded spot is where I have found snowdrops emerging first, and they are further along than those in the patch where a scraping of soil showed the bulbs are still intact but haven’t produced foliage yet. I’m sure autumn rains are a trigger for emergence, but I ponder if they also need to have cooler temperatures to appear, which they are able to get sooner from the waning shade of sweetgum and oak? 

There’s no way that I can grow the multitude of selections my colleagues do further north—well, in absence of a walk-in cooler that is—nor do I wish to become such a collector. But, I’m happy to potentially add yet another geophyte to my garden cast of characters. I may be counting my snowdrops before they have hatched—er, make that returned again next year—but I do believe that seeing them this year in flower is a good sign. I’ll give them my choicest compost with some bone meal, and I’ll hope that next year I can once again be thankful for their return.

Autumn Inspiration from the Dallas Arboretum

Last weekend, I took 23 students to the Dallas Arboretum and Botanical Garden. Each fall, they turn part of the arboretum into a fairy tale village built with pumpkins, and this year they used over 100,000 of them to create such a spectacle. I wanted to share some photos from our trip. Though you may not be able to build a display of thousands of pumpkins, there were other great plants there that can help to enhance your garden for next year. Enjoy the inspiration!

A photo of yours truly (third from right) and other students from SFASU who went on the trip. For some it was their first trip to the Dallas Arboretum.

It is amazing to see how they craft and decorate buildings using pumpkins, squash, and gourds.

A lovely pumpkin mandala pattern surrounds this pumpkin house.

Many areas of the pumpkin village had a theme. Here is a design that features the story of Jack and the beanstalk.

 

And, here of course is the sword in the stone… err… pumpkin.

 

I find myself mesmerized by the pumpkin patterns, seeing them all laid out and in such abundance.

A close up of the pumpkin mandala pattern.

These white and gray pumpkins were used to convey a sense of water in one area near a bridge.

Outside the pumpkin village, the arboretum held other beautiful sights. Symphyotrichum oblongifolium (probably ‘Raydon’s Favorite’) bloomed en masse along this curve.

Here’s a useful lesson in photoperiodism. I was wondering why these asters that were right down the path from the ones in the image above weren’t flowering very well. I suspected at first that the shade had something to do with their lack of blooms, but once I looked up, I saw there were lights in the trees. Asters need short days to initiate flowering, and the blooms were interrupted by the lightning. Those along the lower edge are probably shaded enough to flower.

Hamelia patens 'Grelmsiz' LIME SIZZLER (firebush) is a wonderful foliage plant for sunny spots, and the leaves redden with abundant light. Here in the deep south our seasons are long enough to even get some black fruit to form (center right).

Another shot of Hamelia patens 'Grelmsiz' LIME SIZZLER (firebush), only this time the plant was in full shade. Like with the asters above, as a curious plantsman I love seeing plants growing side by side in different environments and how they react accordingly.

From top left to lower right, Canna ‘Cannova Yellow’ (canna), Plectranthus scutellarioides ‘Main Street Beale Street’ (coleus), Alternanthera ‘Little Ruby’ (Joseph’s coat), and Portulaca ‘Colorblast Double Yellow’ (purslane) fill this bed with color. In the Plantery, we’ve had good success with both ‘Main Street Beale Street’ and ‘Little Ruby’ in summer annual plantings.

The Dallas Arboretum plantings capitalize on creating a show. To me it is interesting to see the juxtaposition of the rising tropical Alocasia (likely ‘Portora’ elephant ear) and the fall Chrysanthemum (mums).

I love visiting plant trials at the Dallas Arboretum to learn about what cultivars do well in our area. Here, left to right are Euphorbia hypericifolia DIAMOND SNOW, DIAMOND MOUNTAIN, and ‘Inneuphdia’ DIAMOND FROST. DIAMOND FROST was a good intermediate between the two for growth, not too short and not too lanky.

I was eager to see their Profusion zinnia trial to see which cultivars looked best late in the season. The three I was most impressed with were Zinnia hybrida ‘Profusion Fire’, …

…, Zinnia hybrida ‘Profusion Lemon’, …

… and Zinnia hybrida ‘Profusion Red and Yellow Bicolor’. My colleague Carol Reese turned me on to this cultivar for how the ray florets shift from a rich yellow and red at opening to a faded pink over time.

I’m a sucker for a good celosia, and I was most impressed with Celosia plumosa ‘Flamma Orange’, which was named a 2022 All American Selection winner. I’ll be sure to add this cultivar to next year’s seed wish list.

I was surprised to see an anise hyssop thriving in Dallas. Usually, we are too humid for them, and they melt. But, the peach-colored Agastache MEANT TO BEE ‘Queen Nectarine’ looked fabulous.

I was reminded in seeing their Osteospermum trial that I need to try my hand at more African daisies. My favorite selection was this BRIGHT LIGHTS HORIZON ‘Sunset’with its warm, vibrant pink flowers.

 

‘Candy Cane Chocolate Cherry’ pepper has variegated leaves and variegated fruit!

 

Last fall, I was very impressed with Celosia argentea var. plumosa ‘Dragons Breath’ (celosia) that we grew in the Plantery. The foliage turns brilliantly colored red as the days shorten in full sun, and they are topped with fiery panicles of blooms.

We saw a couple of Monarchs working this Salvia ROCKIN’ PLAYIN’ THE BLUES. Even in the fierce winds, they clung to the racemes with all their might. They seemed to really like this cultivar. They would fly off and come right back.
