Foliage Follow-Up, July 2015

Posted on July 16, 2015 by Tina

Welcome to hot July in Central Texas and to the monthly, leafy meme of Foliage Follow-up. Thanks to Pam at Digging for hosting.

The pond in my Texas garden cools and soothes when the Death Star arrives and is in full force.

Temps are hot and so is this foliage combo.

Pretty in purple Ruby Red Runner, an Alternanthera hybrid, has spread to the bog from its original spot as a waterfall filter plant.

I like its creeping ways though, and it shouldn’t travel too far afield from the pond itself, as it requires water. If you read this blog, you know that this gardener, doesn’t water that garden–not enough anyway for a water-loving plant to take over. All of the surrounding foliage beauties are water wise and appropriate pond companions: Softleaf Yucca, Yucca recurvifolia, Firecracker Fern, Russelia equisetiformis, and Mexican Feathergrass, Nassella tenuissima.

I especially like the leaves of the Pickerel Rush during the summer months. The lush green, heart-shaped form lends a tropical feel in contrast to the blasting from the sun.

As well, the Ruby Red Runner, intertwined with the large Pickerel leaves, adds a bit of spice.

What cool foliage do you have in the garden this July? Show them off and then pop over to Digging to enjoy other hot July foliage.

Yuck-ah

Posted on February 18, 2015 by Tina

This is what became of my lovely Soft-leaf Yucca, Yucca recurvifolia.

The nascent pup shows the discoloration common with a probable fungal infection from growing in a too-wet soil.

Additionally, the large root came out of the ground without complaint and was rotted, stinky, and mushy–those last two terms aren’t technical, but they are descriptive.

Yuck.

I don’t have a good shot of them, but there were also fat, gross grubs in the mass of squishy, smelly root. The grubs crawled back into their fetid lair before I took these photos and I wasn’t going to stick my hands or even a trowel into the disgusting mess to look for them. You’ll just have to take my word that they exist.

Here’s a head of one, though, in case you’d like to look at it.

I wrote about my concerns for this yucca in December 2014 in this post. Once I removed the mature plant, I hoped that the root with the yucca pup would survive and thrive. At that time, the pup looked healthy and the root was firmly ensconced in the ground, so my positive outlook for the health of the yucca was reasonable. Alas, I believe over watering by the neighboring lawn zealot truly did this yucca in during winter. I think fungal problems were established and the damp of winter took care of the rest.

It’s a bummer, losing this yucca. I’ll miss the evergreen form and gorgeous, twice per year bloom stalks. Oddly, I don’t have a photo of the deceased yucca, but this is another Soft-leaf Yucca in my garden,

…and it, as well as the other eight specimens, seem healthy. Soft-leaf Yucca is striking in the garden–foliage and blooms add so much in grace and structure.

I’m not going to run out and buy anything to plant in the newly vacated spot. If design was my priority, I would replace the yucca with something else that is evergreen with interesting structure. Instead, I planted these two dormant Plateau Goldeneye , Viguiera dentata.

They’ll flourish in the western exposure and they can handle much, or little water–whatever is dealt them. I pulled these two out from a work area at the side of my house where they receive no water from me–they established themselves because that’s what Goldeneye do. An excellent wildlife plant, attracting pollinators and birds, Goldeneye are pretty too.

Really, really pretty.

The two perennial Goldeneye, planted together with others in this garden, will make a bold statement along the street and edge of my property and provide sustenance for wildlife throughout the growing season.

Irrigation SNAFU

Posted on December 11, 2014 by Tina

You can’t pick your neighbors.

A pithy statement, to be sure. While it might be true, another saying I’d like to introduce–Friends don’t let friends over water–also appeals to me. I don’t live in a neighborhood that is particularly, um, progressive in the realm of home gardening. Especially for a neighborhood in a region which is experiencing severe drought conditions. Each of the mostly sterile, water-wasting landscapes throughout my neighborhood showcases a blank slate of water-guzzling St. Augustine lawn as the major “garden” feature and many are situated in full Texas sun. These properties require loads of mowing, edging, fertilizing, and irrigating.

There are a couple of folks who understand the value of home gardening and landscaping as a low-maintenance, water-conserving, perennial and wildlife friendly endeavor, but not many.

And I don’t live next door to either of those folks.

This is the result of over watering a Soft-leaf Yucca,Yucca recurvifolia, compliments of a neighbor who is an enthusiastic St. Augustine lawn waterer.

Beginning in early August, this poor thing developed spots on its straps, which quickly spread, rendering each strap a mottled mess, which then died. I couldn’t figure out what the cause of the diseased foliage was, but I pruned the disfigured and dying foliage, strap by strap.

Damage from an insect infestation? I searched and couldn’t find any offenders. Some sort of disease of Soft-leaf Yucca? Always a possibility, though literature doesn’t suggest this species has any real disease problems. Additionally, I have eight other Soft-leaf Yucca plants thriving in my gardens, from full sun,

…to deep shade,

…and everything in between.

There were and are no disease issues with any of those other yuccas. The only variable with the sickly yucca that differed from the others was the weekly irrigation courtesy of the neighbor. I don’t water often–primarily my gardens are watered only with rain. I pruned the mottled and dead foliage in hopes of stopping the necrosis and eventually the yucca sported a tree-like shape which was fun and quirky. I thought the yucca might survive.

One morning though, I found a rotted and toppled-over yucca.

Yuck-ah.

Well, there wasn’t much I could do, except to cut my losses, or rather, the yucca, toss the mess into the yard waste can and stand there, hands on hips mulling my next step. I considered digging up the whole root, but alas, the yucca root is too large for that. Of course it is. It’s a xeric plant and its xeric-ness comes from the massive root system, really a type of rhizome, that the mature plant develops. Also, there were pups growing,

…and rather than disturb them, I left the yucca root in place with its new, seemingly healthy growth.

My neighbor, Mr. I-Gotta-Water-Every-Week-No-Matter-What, watered his St. Augustine grass. Every week! You could set your clock by his schedule. I couldn’t really complain because he watered on his assigned day, during the accepted hours, and though more water than necessary ran down the curb, it wasn’t horrible. Trust me, I’ve seen worse. What I didn’t realize during those months was that the yucca was probably watered every week. I never thought to check if his overhead sprinkler was watering my garden, which borders his property. Because of its massive root, the yucca doesn’t require much irrigation. Once I connected the rotted yucca with weekly summer irrigation, I realized the cause of the once-healthy yucca’s demise. The hardy Soft-leaf Yucca had received much too much water for its needs.

I should add that Y. recurvifolia is not native to Texas, but to the Southeastern part of the U.S. I doesn’t mind a little irrigation from time-to-time, but certainly doesn’t like wet feet or require regular watering.

That’s why I plant what I plant–so that I don’t need to water often. There are many benefits to using native and well-adapted, drought-tolerant plants in a home garden, and conserving water is certainly at or near the top of that list. But the prevalence of St. Augustine grass, especially in full sun and as a primary landscape feature, is not a regionally appropriate choice for Texas. To look good, it requires more water than should be wasted on a landscape.

I left the little pups that were emerging,

…and they’ve grown. I’ll talk to my neighbor next summer to explain why I don’t want extra water on my garden. With our lakes (the prime water source for Austin and surrounding areas) down to about 30% capacity and heading toward a historic low, he might not be able to water anyway because of tighter water restrictions.

His grass will struggle with those restrictions, but my gardens will continue to blossom and boom.
