Loss of roadside vegetation

My previous post mentioned a September set of observations – unfortunately, the observations were not posted to this blog but on Facebook. Sad to say, the situation has gotten worse – Although the native (mostly) plants  were left alone while in bloom in September, the blooms had disappeared a few. months later, and this first week of March 2021, I observed that the plants, for the most part, appeared to have been removed.  Thanks to the ongoing pandemic and my age, I try not to go out too often. but will have to go out and see if any Winecups are in evidence (there was at least one rosette in the video). Maybe take a few home to ensure the preservation of the species. The folks running City Hall don’t seem to care about preserving native plants… as far as I can tell. Oh well. Watch it and weep.

The irony of the last few slides are that they show the invasive Crepe Myrtle and Heavenly Bamboo or Nandina, used as landscaping in the property just south of. the one now being bulldozed for a parking lot and who knows what kind of business. I suspect that a similar lack of consideration for native plants, birds, and other wildlife will guide the development of this property.

Gone to seed, fruits, or berries, mostly…

Took a walk out in the woods, in the middle of the summer, to see if the Phemeranthus calycinus aka Rock Pink, might be in bloom, since we had had several days of rain prior. No such luck. There had been at least 20 specimens in the immediate area about four years ago, and earlier this year I found one in bloom, but even the Bitterweed (Helenium amarum) seemed to be scorched, for the most part, although I did take a photo of one that wasn’t, and some grasses. (For an article describing the flower I was looking for, and some photos, see Stalking the ephemeral Rock-Pink).

The area I’ve dubbed “Lace Cactus Lane” because of its concentration of Echinocereus species, was in fairly decent condition. And a pass through the area I call “Vine Street” revealed some Pearl Milkweed Vine (Matelea reticulata) pods dried and open, as well as some Carolina Snailseed (Cocculus carolinus), starting to put out its berries. Of course, there was the usual Poison Ivy (Toxicodendron radicans), Virginia Creeper (Parthenocissus quinquefolia ) and Sevenleaf Creeper (Parthenocissus heptophylla). And I took a few shots of the Bearded Swallow-Wort vine (Cynanchum barbigerum) just to illustrate the way it braids itself along whatever is supporting it.

A bit closer to home, Butterflyweed (Asclepias tuberosa) were in bloom,  as were Texas Lantana (Lantana urticoides) , Apache Plume (Fallugia paradoxa), Gregg’s Mistflower (Conoclinium greggii), Mealy Blue Sage (Salvia farinacea), Skeleton-leaf Golden-eye (Viguiera stenoloba),  Four-nerve daisies (Tetraneuris sp.), Flame acanthus  (Anisacanthus quadrifidus), Autumn Sage (Salvia greggii), and Manzanilla (better known by the name Turk’s Cap, and rarely called Texas Red Mallow)(Malvaviscus arboreus var. drummondii). Even the Wild petunia (Ruellia nudiflora) has been putting out blooms lately, and the Yellow Passion Flower (Passiflora lutea) seems to have just recently finished its latest cycle.

Which leads to a mention of the life cycle of the Gulf Fritillary (Agraulis vanillae) butterflies, which have tried their best but haven’t succeeded in stripping the Passiflora vines completely this year. Given that it is safe to speculate that the suburban subdivision where I reside has little habitat for these beautiful pollinators, one can only hope that my little nursery is keeping the local population going.

In the heat of the summer

I seem to suffer from Gilligan’s Syndrome – what starts out as a five minute walk outside to water the plants in their containers that I am hoping will hold on until cooler weather comes (September? October?) turns into an hour or more photo safari. Sometimes I go beyond the confines of my yard, sometimes not.

Ruellia nudiflora, for instance, has suddenly been blooming like crazy. A Passiflora incarnata volunteer popped up in the mulched bed across from the Passiflora lutea and Passiflora suberosa, and started putting out blooms. The Malvaviscus arboreus var. drummondii continue to bloom, as do the Salvia greggii, Lantana urticoides, Scutellarria wrightii, Salvia farinacea, and Conoclinium greggii. In the “nursery,” several Asclepias milkweeds have bloomed or budded, along with Tetraneuris scaposa. In the gravel pathway, I had to (reluctantly) trim the Boerhavia coccinea back to allow human passage. The Fallugia paradoxa has put out a few blooms and plumes, and the Pavonia lasiopetala has been a pleasant surprise with its hibiscus-like pink blossoms.

We have Liatris punctata still in bloom, Melampodium leucanthum, Asclepias texana, and a native grass that I have been calling “Indian Grass,” (turns out that is the common name for Sorghum nutans. The Aloysia gratissima has attracted pollinators, as has the Anisacanthus quadrifidus, and behind the fence, the Proboscidea louisianica or “Devil’s Claw,” has held out with a bloom or two. The Glandularia bipinnatifida has come up in various spots, too low for the mowers’ blades most of the time. As can be seen in some of the photos, these native plants of Texas, most of which are not receiving any supplemental watering, provide food for Bumblebees, butterflies, and even hummingbirds, lizards, and wasps. I even went out and over the course of several days, harvested enough Diospyros texana fruit to make a Texas Persimmon Loaf. The slide show that follows includes photos taken the week of August 10 – 16, 2020

Oops! They did it again.

As in, “They mowed the berm between the greenbelt and the houses when it didn’t need mowing.” (See slideshow at the end of the post).

I had just gotten back inside the house, after taking some photos of plants in my yard, and had gone out into the berm, to document the healthy growth of Silver Bluestem that had risen up after the most recent massacre at the end of May. While not as thick as one might wish, it was good to know that my removal of the Perennial Rye and Malta Star Thistle had allowed the native grass to come back.

Looking on the bright side, it appeared that the mower’s blades had been set at a higher level than before. Whether they pressure washed the blades before mowing, I don’t know. Since I have not received the courtesy of a reply to my emails in February and June,  I don’t know. And the Johnson Grass, which I’ve been pulling out or removing the inflorescences from so they don’t go to seed, were mowed down, leaving the Poison Ivy more or less intact, so that it will be easier to go out and apply an herbicide to eradicate. And at least they mowed while the ground was dry.

So while I am still not happy with the apparent frequency of scheduled mowing, it seems that my attempts to enlighten and educate those responsible has made a small dent. Persistence will tell the tale.

Natives returning, along with a few undesirables

A month after the Wildflower Massacre at the hands of untrained/poorly trained mowers (who are not to blame, for the are just pawns in the game), the native plants are making a strong comeback, as well as a couple of unwelcome plants, both exotic and native. Among the invasive or undesirable plants are Johnson Grass (Sorghum halepense), Bermuda Grass (Cynodon dactylon), and Poison Ivy (Toxicodendron radicans). Interestingly enough, most of the “new” natives are coming up in the area in which I had already pulled some 10 bags of grasses and weeds of the exotic and invasive persuasion. But enough talk, here’s a slideshow to illustrate what I’m talking about.

 

The low blade mowing (under 7 inches) according to a personal source expert on eradicating non-native species from parks and preserves, is a great way to spread the Poison Ivy (a native, but one which one prefers left in preserves, untouched by mower blades). I suspect that cutting below 7 inches also encourages the spread of Bermuda Grass. The Johnson Grass is an opportunistic plant that likes disturbed soils such as construction sites or “scalped” roadways and in my case, berms. But it can be easily defeated by pulling it out after every rain, and letting native grasses take over.

Return of the purple leather flower

_MG_08451024jpg

Clematis pitcheri – Purple leather flower

Back in the corner of our tiny lot, next to the compost bins and under the Diospyros texana, is a gallant vine that until now has shown no intentions of putting out any flowers.

Yesterday was the first day a bud showed up, so maybe it will get some followups as it matures, or other flowers come out. The Texas persimmon mentioned by its scientific name above provides the majority of the foliage in the photo above. but the Clematis leaves can be seen, they’re just much larger and out of focus.

Yesterday, while sitting on the back porch/deck, a titmouse came up to the trellis and started poking its head about. As I fumbled with my camera, I was able to get about four poorly focused or poorly framed shots, so my best guess is that it was a tufted and not aa black crested titmouse. As I tried to follow it around the yard after it left the deck, I took several shots of dubious quality. I was surprised to find that instead of the aforementioned bird, the next best shot was of a Carolina chickadee. Naturally, after the initial excitement of tiny birds flitting about the yard, I was left standing holding the camera without any feathered bipeds in sight, though I could still hear them singing – mostly a mockingbird.

Which I guess is why I mostly stick to plant photos – at least they stand still, more or less, except when the wind blows, or even breathes a whisper across them.

Endemic in a time of a pandemic

2020_04_10_Clematis_texensis_1521

Clematis texensis – Scarlet Leatherflower

I just realized that there is an analogy between the pandemic coronavirus now causing troubles throughout the planet’s human organizations and the title and subtitle of this blog  – “Return To The Natives – Native Plants Are The Answer.”

C. texensis is endemic to the Texas Hill Country, or the Edwards Plateau, although because of the scarlet flowers, it has been exported to other locations for cultivation. However, it doesn’t seem to be an aggressive plant, so most places outside of Texas where it is found are probably in containers, where they are tended carefully by loving horticulturists.

The example shown above is a next door neighbor example of this phenomenon: Although it it is in Williamson County, TX, it was introduced and is under cultivation. I don’t know of any locations where it is growing in Williamson County without having been introduced by humans. But – it is native to Texas, and to neighboring counties, and who knows? – there might be some undiscovered instances of this species in the Balcones Canyon National Wildlife Refuge.

Unlike some other plants, like Poison Ivy, Malta Star Thistle, Perennial Rye, and Bur Clover, which are aggressive and spread rapidly when they are introduced to an area through human intervention, often by poor mowing practices, this one is unlikely to dominate your garden. But with the right conditions and in the right place, it can and will flourish in Central Texas.

More detailed information on Clematis texensis can be found at Studies on the Vascular Plants of Williamson County, Texas. If that is too much detail for you, there’s always the Native Plant Information Network (NPIN) database at the Lady Bird Johnson Wildflower Center

The analogy mentioned above?

The pandemic virus is like an exotic plant that is introduced to areas where it doesn’t belong – and spreads, unchecked, unless we take quick action to recognize the problem and isolate, treat, and follow up on contacts, to eradicate and mitigate the adverse effects. The same analogy applies to invasive animals, whether Zebra mussels in the lakes of the South, or pythons in the Florida Everglades. It’s hard to get the genie back in the bottle, or to get everything back inside Pandora’s box.

Stay home. Practice good hygiene, whether traveling or working with plants. The only thing that can prevent pandemics is you, to borrow a slogan from a well known fire prevention campaign.

Plant and grow things that are native to the area in which you live – practice proper hygiene when traveling from place to place, being careful not to spread seeds through carelessness, and if you gotta mow, mow only at the right time and the right places that need mowing for the primary reason of safety. Bermuda grass is hard to eradicate once it has spread, and viruses are hard to kill but easily spread through careless hygiene practices.

Don’t “stop to smell the roses” – Learn about the plants that are native to your area, and take the time to enjoy them and their relationships with the wildlife, butterflies, and native bees that are in your six feet of separation.

Seasonal post-bloom fine-feathered achenes

Old man's beard (Clematis drummondii)

Old man’s beard (Clematis drummondii)

It’s getting on past halfway through summer and the Clematis drummondii are starting to show off their old man’s beards – which is interesting, since this plant has both male and female plants – the stamens are sterile on the female plants, and the stigma on the male plants are probably sterile too, I would guess – haven’t seen it documented anywhere yet.

Another common name for these flowers is Virgin’s Bower, or Texas Virgin’s Bower. Go figure.

Agraulis vanillae Gulf Fritillary Butterfly larva

Agraulis vanillae Gulf Fritillary Butterfly on Passiflora sp

Agraulis vanillae Gulf Fritillary Butterfly on Passiflora sp

 

While the Gulf Fritillary, as the name implies, is native to the area surrounding the Gulf of Mexico, but its range actually extends far beyond that. It is found as far south as Argentina and as far north as San Fransisco, according to Wikipedia.

Here it is on one of the Passiflora vines, one which is not native to the part of Central Texas where I live. It seems that one cannot find locally native plants unless one digs them up, which can’t be both ethical and legal, or manages to find some that have gone to seed and from which a small taking of seed would not endanger reproduction in the natural state.
