I googled Gaura biennis, biennial beeblossom they call it, what a lovely name. I think it looks as nice as the one I have. Biennial compared to perennial though, I prefer the latter.
I hate to admit this, I have never seen a Hosta. I must Google that also. Oh, it is too, Hazel, very like it. I wonder if Hostas would survive here? Yes, zone wise they'd be fine. They are the plantain lily, and the Crinum mooreei is the bush lily. Hostas might be even nicer, more flowers and more interesting foliage?
