Name: josephine Arlington, Texas (Zone 8a) Hi Everybody!! Let us talk native.
It is good that you have a wet area, I think Buttonbush is beautiful and the butterflies love it.
I am also going to suggest Frostweed, Verbesina viginica, it is native to your state and great for butterflies as well. http://www.wildflower.org/plan...
