Beautiful shrub for the herbal hedge. It has large white flowers in the spring and pretty red berries in fall much favored by birds. The bark contains valeric esters and the tea or tincture of the dried bark effectively alleviates menstrual cramps and other types of muscle spasms. The bark can be harvested sustainably from the yearly spring pruning so as not to destroy the shrubs. Lovely addition to a fenceline or herbal hedge beautiful fall foliage. Perennial Hardy to Zone 1.
