It took me a few weeks to do this, because burying those big stones was no easy task. Just did a few at a time.
You can see in the photos above that I started planting around that path and the front garden with 54 Carex retroflexa var. texensis. These are great sedges that I've used in the back already. Here's what they look like there all grown up:
They come from Barton Springs Nursery. And amazingly, I could probably use about 36 more of them up front. I'm going for a very wavy, lush, grassy look up there with just a few main species. I've also planted small Mexican feathergrass clumps all around, and a few bamboo muhly in the rear (since they get so large). I'm also planning on planting some side-oats gramma when I find it. (It's the state grass of Texas, by the way).
The Blackland yucca (Yucca pallida) dotting the area were picked up at Madrone Nursery, which is a killer place to visit and buy plants - by appointment only. Dan seeded these pale blue yuccas from some growing wild around the Dallas area. They have a wonderful yellow edge that glows when backlit by the sun.
