Rating MYSELF as negative since I planted this plant in my zone 9a garden, which is too hot for it. Don't waste your money if you garden in z9 or warmer.

I planted one of these last year, but then I moved it a couple of times. Thought I had probably killed it, but it is growing and blooming this year. In my experience, baptisia takes a few years to really do much, and then it becomes very robust.

I have this and Starlite Prairieblues planted side by side. The solar flare did not have any blooms this year where the purple Starlite did. I also noticed the ones at my local nursey were also not producing flowers. .
