Propagate by division or separation - Divide the tubers when planting out in the spring.

In late winter or early spring, plant the tubers 1" deep in flats of peat and sand. Keep the soil moist but not soggy, and at a temperature of at least 70 degrees Fahrenheit. When roots appear, pot the tubers individually. Maintain them in a warm, moderately lit place until all danger of frost has passed.

After frost danger has passed, the plants may be moved outside to beds or planters. In excess shade, the plants will lose their color; in excess heat, they will burn.

In early fall, before frost danger begins, gently remove the tubers from the beds, or bring the pots indoors. With the soil around the roots intact, place the tubers in a warm (60 degrees Fahrenheit) well-ventilated place until the spring.
