Region: Lower Plains
Very tolerant. I planted mine in a small hole in hard clay--poor draining. Full sun by the pool. Little water or fertilizer. It has made it through three winters with no protection, not even mulch. It is sending up three flower stalks right now.
The only "problem" is that they are becoming common. The local WalMart has a parking lot filled with them.
However, I loved being able to look at a healthy plant all winter as most everything else suffered.
I'll plant more this year. --Erik
