I am having a dickens of a time with this plant. Anybody got any hints? I have it in a very lean, very fast-draining mix. Surface of pot is mulched with turkey grit to try to keep the crown as dry as possible. It hasn't died yet, but as soon as the new leaves get about 6" long, they give up the ghost. No sign of a flower. I have it in full sun and am wondering if that is the problem. Catharine, Atlanta, zone 7b
