I just love them. I live north of Austin. They are perennials growing wild on our 42 acres east of Austin.
I don't do a thing to them but water when we drive to the cabin every few weeks to mow the yard right around the cabin. They come back every year in three spots down there, but all in the back yard sort of out of view unless I'm walking the entire yard. They have never fruited though. I might try fertilizing them this year and see if they produce fruit. Pollination sure shouldn't be a problem, because there are wasps, moths, butterflies, hummingbird moths and bees galore there in spring/summer.
