    Growing it

    Propagation
    division, cuttings
    When to plant
    spring
    Overwintering
    In cold climates, lift the tubers in autumn after the first frost. Store them in a cool, dry place packed in peat moss until spring.
    In containers
    It grows very well in pots, provided you use a large container and keep the soil consistently wet.

    Division

    1. 1. Dig up the plant in spring.
    2. 2. Separate the offsets or cormels from the main tuber.
    3. 3. Replant the divisions in moist, rich soil.

    Group moisture loving plants together to create a humid microclimate that helps them thrive.
