Pinebarren frostweed is a perennial mound-shaped subshrub that occurs naturally in sandhills, dry flatwoods, dunes and other dry, sandy areas. Its delicate lemon-yellow flowers bloom spring through summer and attract a variety of pollinators. Blooms are many, and they last only one day.
Pinebarren frostweed flowers are five-petaled and slightly concave, coming together as a shallow bowl. The petals have ragged, squared-off edges. The pistil is superior, meaning it is attached above the petals and entirely visible. Stamens are relaxed and tend to lay flat against the petals. Anthers are bright orange. Flowers are arranged in corymbs, giving the inflorescence a flat-topped appearance. Leaves are elliptic to linear with deep venation. Margins are slightly revolute. Seeds are borne in capsules.
The genus name Crocanthemum comes from the Greek crocos or yellow. The species epithet corymbosum refers to the corymbose arrangement of flowers.
