Chocolate Joe Pye Weed

Chocolate Joe Pye Weed, also called Chocolate Snakeroot, is an herbaceous perennial grown for its dark foliage and airy white flower clusters. Its purple stems carry chocolate-brown leaves that provide contrast from spring into summer, with flowers appearing in summer and early autumn. ## Foliage and flowers The cultivar forms an upright clump, with white flowers held in rounded clusters above the darker leaves. The Royal Horticultural Society gives a mature height and spread of 0.5–1 metre; other regional references describe smaller plants, so allow for variation with conditions. The flowers extend the display into autumn and can be used in informal borders or wildlife plantings. ## Siting Partial shade helps retain the rich foliage color. It grows in clay, loam, or chalk and prefers moisture-retentive soil that drains reasonably well, though it can tolerate poorly drained ground. Keep it watered during dry spells, especially in sunny exposures. ## Maintenance Cut faded flower stems back to the base and divide in spring if needed. Handle the plant carefully and do not consume it: white snakeroot is associated with livestock poisoning.
