    I grow these both in pots and in the ground here in Central Florida zone 8b/9a. They grow from a rhizome and usually emerge in very late May or early June when the soil temperature is warmed up into the 60's. This particular variety, 'Purple King,' produces a large purple bloom. They like moist well-drained soil, and drying out too much can induce early dormancy. They usually go dormant in late September to early October here. I don't lift the ones in the ground. I store the ones in pots in their pots, in a cool dry place until spring.
