I have this outdoors in a container larger than the beautiful plant in the photo, but my plants never bloom. They don't grow so large, either. What might I be be doing wrong? I leave them out all year in dappled shade and I water them all year. The tops tend to die to the ground when it gets hot for the summer (say, over 104F / 40C) and then resprout in the fall, growing all winter. They don't seem to freeze in our moderate overnight frosts. My bulbs are from a friend in St Louis, Missouri, who digs them each fall, stores them in her garage over the winter, and replants them in spring. They bloom for her in early summer.
