I went to a new nursery in Pflugerville that specializes in native plants. It had a really nice collection, and a few plants i have never heard of. I asked the owner for suggestions for Edward's plateau.
Sneezeweed
First he suggested Sneezeweed. It was only after I arrived home that I learned that this plant likes moist clay soil. I planted these three plants in the front flower bed, but I am not expecting them to make it through the summer.
Longleaf BuckeyeEriogonum longifolium var. longifolium
He also recommended Longleaf Buckwheat, which is native to the Edward's plateau. I planted it behind the Spanish Dagger. It doesn't look like it will be an overly pretty plant, so I thought it might just add it as a backstory plant. It does say it is very draught tolerant, once established. It says it dislikes root distubrance, so we will see how it adjusts to being platned
Sandpaper Tree
Ehretia anacua
The owner mentioned that this is a great plant with edible fruit, so I thought Kyle would be excited by it. He mentioned that it is more of a southern plant, but there are some in Austin that do well. After getting home, i read that they may freeze back to the ground in Dallas, but unsure how it will do in Austin.
I planted it in the back year. We will see how it does.
