A near relative of Joe-Pye Weed, and also used in medicine, the parts desired being the flowering tops, gathered when in full bloom, and the leaves, stripped from the stalks and quickly dried, for which collectors receive three to eight cents a pound.

Stem two to five feet tall, rather stout, hairy, branching at the top. Leaves deep green, long-pointed, opposite, and united at the base, seeming like a single leaf through which the stem has grown, downy beneath, somewhat wrinkled, prominently veined, finely scallop-toothed. Heads very small, in rather compact corymbose clusters, dull white or very rarely blue, the florets all perfect and fertile; as they mature, the lengthening and expanding hairy parachutes of the achenes make the clusters appear like fleecy tufts of wool.

Means of control the same as for Joe-Pye Weed.
