Late this afternoon, as I was driving the block from the oasis to the house, I saw an interesting plant alongside the road, so stopped (abruptly) and snapped a photo, hoping to ID it and see if it's good for butterflies. I posted these photos of it on the W TX Xeriscape Facebook group and they thought it was acourtia wrightii (commonly known as Brownfoot or Perezia). That's a new one for me. I'm always amazed by what grows here. I'm going to try for better photos tomorrow. The leaf edges are prickly, and it's not a milkweed.
I just wish I had the time and energy to see what else is growing on my place. I know there's bound to be some great stuff. Whenever I do get out and about, I find awesome plants.
One last photo. It's of some caterpillars that will turn into Bordered Patch butterflies.They're all over the oasis, not unexpectedly, since I had an infestation of them last year. Gorgeous butterflies, and there's no shortage of sunflower leaves for them to eat.
