I love the idea of a flowering shrub that is also a legume that enriches the soil with nitrogen, and Bush Clover flowers are lovely, too.
There seem to be a lot of species and varieties, but most are leggy and not very floriferous. Does anyone have any experience with them? Have you noticed particular kinds that have nice forms and more flowers. It would be especially nice if I could find one that would continue to bloom throughout the warm months.

I have grown lespedeza thunbergii and have had good success it has a nice shape and looks great in full bloom. I have had it in the ground for about 3 years and it is about 5 feet across and maybe 4 feet tall right now. Hope this helps.
