This fascinating plant is one of the first to emerge in early spring, often pushing through frozen ground. It gets its name from the pungent, skunk like odor it releases when the leaves are bruised. It thrives in wet, swampy areas where it can keep its roots constantly saturated.

    Growing it

    Propagation
    division, seed
    When to plant
    spring, autumn
    Overwintering
    No special care is needed as the plant is fully hardy and naturally dormant in winter.
    In containers
    It is not suitable for standard containers due to its extreme moisture needs and deep root system.

    Division

    1. 1. Carefully dig around the massive root system in early spring.
    2. 2. Use a sharp spade to divide the clump.
    3. 3. Replant immediately into a very wet location.

    Group this plant with other moisture loving species to create a self sustaining wetland patch.

    • It is one of the first plants to bloom in the spring, often pushing through frozen ground.
    • The leaves can grow up to 60 centimeters long after the flowers fade.
    • It has a massive, deep root system that makes it very difficult to transplant.
