    Growing it

    Propagation
    seed, cuttings
    When to plant
    spring, autumn
    Overwintering
    No special winter protection is needed once established. A layer of mulch around the base helps maintain soil moisture and protects roots from extreme temperature fluctuations.
    In containers
    It is generally too large for long term container growth, though dwarf cultivars can thrive in large pots for several years.

    Seed

    1. Scarify the hard seed coat with sandpaper.
    2. Soak seeds in warm water for 24 hours.
    3. Plant in moist soil and provide a period of cold stratification.

    Plant understory perennials around the base to keep the root zone cool and moist.

    Grows well with

    • Serviceberry — They share similar woodland habitat requirements and bloom at the same time.
    • Hosta — These shade lovers thrive under the canopy of the redbud.

    Similar species

    • Chinese Redbud — It is a smaller, shrubby relative with more intense flower clusters.
