Well, I hope to add a couple of Amsonia species, white and bluish. They are natives so maybe they'll do okay. I have seed for one and the other one is at a native nursery...will get it in the spring. So glad I've discovered that this species can grow in southcentral Texas! One thing I try to do is grow plants that don't have to be babied and will survive an area like mine...an area that can be pretty challenging for plants!
