It forms a clump of large, mean-looking, spiny, green leaves and produces dramatic, upright spikes of hooded blooms rising above the foliage. Avoid wet soil conditions in the winter.
Apply mulch in the fall for overwintering. Acanthus do not like to have their 'feet' wet in the winter months. May take a few years to flower, but are worth the wait. Once the blooms are finished, they should be cut back to encourage new foliage growth until frost.
