    Propagation
    seed
    When to plant
    spring, autumn
    Overwintering
    The foliage will die back completely after the first frost. You can cut the stems to the ground in late autumn or early winter.
    In containers
    It is generally too large and aggressive for container gardening.

    Seed

    1. 1. Collect ripe berries in autumn.
    2. 2. Clean the seeds from the pulp.
    3. 3. Sow seeds directly in the garden in autumn for spring germination.

    Give this plant plenty of space as it can quickly crowd out smaller perennials.

    • Goldenrod — They share similar habitat requirements and bloom times.
    • Aster — These provide a nice visual contrast in late summer gardens.

    Similar species

    • Inkberry — It is a closely related species with similar growth habits.
