The Natives are Restless

Native Texas plants are back in action!  March always heralds the time of the natives, and many are eager for the season to begin.  They’re  budding up and blooming out!  It’s true that several of my non-native plants are, or have been, blooming:  irises, poppies, and Mexican honeysuckle.  But this native Texan  appreciates native Texas plants which are lovely and posses the evolutionary chops to weather the weird–no matter the confusion of seasons or the Texas weather patterns.

 

This sweet thing is a hybrid columbine, a cross between the native Aquilegia chrysantha and another native, Aquilegia canadensis.

I grow the two different columbine species in my garden and the plants hybridize with ease, creating a third alternative, with varying color schemes–sometimes more yellow, sometimes more red.  On this particular hybrid, the butter yellow petals and the blushed spurs show off qualities of both types of columbines.

The sunshine-cheery Golden groundselPackera obovata, is modeling its spring wears, though with less oomph than in years past.

There’s still plenty of pop with these diminutive blooms; there’s no denying that yellow is bright.  But last summer, most of the individual plants in my small patch of groundsels succumbed to the heat and drought.  I didn’t realize that the soaker hose buried in this  garden had developed a leak. While a couple of plants not far from the groundsels received good soaks when during their twice per month drink, these poor little things got none of the wet stuff.  That garden boo-boo occurred during an especially hot and dry spell in August and September, and it wasn’t until the rains returned and the temperatures softened that I discovered that there were few remaining groundsels.

I don’t know if these other rosettes will produce bloom stalks this spring–time will tell–but I’ll certainly keep a better eye on things next summer.  Golden groundsel is a tough native plant which doesn’t need babying,  but two months with no water and hot temperatures is a bit too much to ask of them.  It’s a wonder there are any left!

 

This terra-cotta beauty is the bloom of the CrossvineBignonia capreolata.  

This individual vine grows in shade, up a fence, only producing a few blooms each spring.  Directly across from this vine, at the opposite end of my garden, grows a second Crossvine, also along a fence.  That second Crossvine receives much more sunshine, making many more blooms.  For now, all of its blooms are growing over the fence, where my sister-in-law enjoys them.

Oh, well, I’m sure she won’t mind if I walk over to say ‘hi’ to the wayward flowers.

 

Giant spiderwort, Tradescantia giganteaare solid, reliable spring blooming natives, dotting gardens and roadsides with purple-to-pink clusters.  Each new day as I walk my garden, ever more of these purple clusters appear, petals open for whatever pollinators happen by.  Spiderwort can be aggressive, filling a garden with bright color and fleshy green stalks and foliage.  But its pollinator power and luscious color are well-worth tolerating its bullying behavior.  The thuggy individual plants are easy to yank up and give away!

The first blooms of these plants show up on short bloom stalks, but as the days lengthen, the bloom stalks grow taller, in kind.  Many spiderwort plants in my garden reach up to two feet tall.

And, the bloom clusters are stunning.

As Texas ramps up for the new growing season, the natives are restless.  Native plants provide sustenance for wildlife and beauty for gardeners and wildflower watchers.  Native Texas plants–and there are many for every season and every growing situation–are ready to strut their stuff.

Not only do I celebrate blooming native Texas plants, today is Texas Independence Day!   Hats off to the Lone Star State!

…and so many others. Folks from far and wide travel to Texas to view the spring wildflower show. In a good year, open spaces and home gardens are resplendent with color from all parts of the color wheel.

I don’t grow any of the famed Texas wildflowers in my personal garden. Alas, my soil is too heavy and my space too shady for the prairy/grassland flowers that most identify as quintessential Texas wildflowers.  But I certainly love and grow many other native Texas plants and wildflowers and a favorite in bloom right now is a group belonging to the Commelinaceae family–the pride of purple–Tradescantia or Spiderwort.

There are 19 species of Tradescantia throughout North America, almost half of which reside in Texas.  A woodlands plant, Spiderwort thrive in a variety of soils, but generally prefer part-shade to shade exposure, though it grows well in more sunny conditions, too.  In short, it’s not a picky plant.

I can’t tell you exactly which one of the Tradescantia that are in my gardens because different Spiderwort mix-n-match with one another, hybridizing readily and creating variations in color,

I think the majority of my Spiderwort plants are the Giant spiderwortTradescantia gigantea,  if only because most of them are just so darned tall.

In my garden, Spiderwort blooms for  a rather long period.  Often, the flowering begins at the first of March (if not sooner) and continues well through May. Spiderwort plants are best situated in a more casual garden, though if kept in check, it’s a plant that could work beautifully in a formal setting.  The key phrase is kept in check. Tradescantia re-seed with abandon and can prove weedy and thuggish if allowed to seed out ungoverned. You MUST weed wayward seedlings if they grow where they’re not wanted!  A good time to discipline these rogue germinators  is in winter and early spring, as the seedlings emerge.

If I see a mother plant and scads of babies at her feet AND I don’t want them–out they go! The seedlings are easily removed by hand or with a weeding tool.

Another strategy is to nip Spiderwort in the bud during the blooming season.  Once I notice less flower production, it means that the seeds are developing and it’s time to snip.P1030500.new

I’m brutal with this process because I know that if I’m the least bit kind-hearted, Spiderworts will be everywhere in the garden.  I still get plenty of new seedlings each year, but keeping Spiderworts in check prevents mayhem in the garden of the Spiderwort variety.

Despite its mission to spread, Spiderworts are valuable to pollinators and pretty  for me to relish, and therefore, welcome in my garden–with practical limitations of course. Honeybees adore this plant and Tradescantia are visited by native bees and butterflies too.

From A Seasonal Look perspective, Spiderwort are primarily winter and spring plants. In a wet and cool autumn, the foliage will emerge early; in a wet and cool early summer, the blooms might last into June, the foliage a little longer.  But once the heat of summer sets in and Spiderwort flowers have bowed out and relinquished the flower show to the heat lovers, the foliage…fades away.  I can’t honestly say exactly when the foliage is no more–but eventually, it disappears.  One of my strategies in planting for seasonal flowering is to plant early spring bloomers underneath the larger summer/fall blooming/berrying shrubs (many of which are herbaceous perennials).  I’m certain that those particular Spiderwort plants hang on for a while after the peak of their blooms, shadowed and covered by the limbs of summer/fall plants.  Since the Spiderwort plants are sheltered by the spread and height of the summer shrubs and perennials, I don’t notice what they’re doing–and I won’t notice (or think about) those Spiderwort plants again until winter’s first freeze renders the deciduous perennials inconsequential and the tell-tale grassy foliage of Spiderwort emerges from the chilled soil.  The caveat is that many of the unwanted Spiderwort in my garden occur because I neglect to deadhead those soon-to-disappear-under-larger-plants Spiderworts.  That’s the downside of planting them underneath larger plants: out of sight, out of mind.

For those free-standing Spiderwort individuals that drag into summer, their seasonal end is more obvious.

What typically happens is that sometime in June or July, they become terribly droopy and sad–heat is not a friend to Spiderwort plants.  I relieve any Spiderwort misery with my trusty Felco pruning shears, cutting down the remaining, sad foliage to the soil. The roots stay safe in the ground until more convivial conditions present and ready the Spiderwort story to begin again: lush winter foliage and enchanting spring flowers.

If  basic preventative pruning and/or seedling weeding is employed, Spiderwort is a desirable spring wildflower for the garden with its lovely foliage and flowers, attraction for many pollinators, and easy growing habit.  What’s not to enjoy about Spiderwort?

I appreciate the winter foliage and spring flowers–and who wouldn’t?
