About This Species
Native to Europe, Marsh plume thistle is a biennial that prefers moist to wet, naturally open or disturbed areas. Plants will replace native vegetation in natural areas and are also known to compete with tree seedlings that have been planted in cutblocks. Seeds spread by wind, water, birds, vehicles, and equipment. Marsh plume thistle is considered a noxious weed in parts of BC.
