The unusual blooms of cymopterus bulbosus
consist of thin, whitish, paper-like bracts which contain numerous, small pink/purple florets, opening to display long white stamens. Flowers are arranged in clusters (umbels) of around a dozen heads, at the end of a short, thick stalk. The involucre (the base of the bracts, underneath the flower head) is star-shaped. The plant is low growing, its twice compound leaves staying close to the ground, and the flower stalks also tend to grow sideways rather than vertically upwards.
