originates in Europe and Asia but is long established in the Americas. The plant produces small but densely-packed, egg-shaped clusters of thin, elongated, tubular florets, numbering up to 200, with the cluster about 1.5 inches in diameter. Individual flowers are usually colored light pink, darker at the tip, but can sometimes be nearly white.
The three-pronged leaves grow all along the stems, including right beneath the flowers; those towards the base have long stalks, while the leaf margins are finely hairy (ciliate). Leaves have a distinctive lighter patch towards the tip. Fruits are small pods containing only one or two seeds. The plant is common all across the West, in most environments except deserts and high mountains.
