Have you grown Gaura biennis?
I'm considering Gaura biennis for a very small (15' x 15') meadow planting in my yard. If you've grown Gaura biennis (as opposed to Gaura lindheimeri or other perennial species), what do you think of it? In particular, does it stay upright or flop in your garden? How tall does it grow? And how showy is it?
Thanks for any information.
