Sunrose Frostweed - Pine Barren Sunrose
Crocanthmum corymbosum (Michaux) Britton
Cistaceae (Rock-Rose) Family

This region is blessed with two individuals in the Rock-Rose family; the Carolina Sunrose and the Pine Barren Sunrose seen here. One description essentially fits all in that their characteristics are virtually the same except for the leaf and flower color. These perennials of dry, open sites flower only in the sunlight, a fact which explains the generic name. In both cases, a solitary flower terminates a main stem, which later in the season clusters of inconspicuous, bud-like flowers are produced in the axils of branch leaves. The preferred habitat is dry, sandy, or rocky open woods and openings. Distribution is primarily salt marsh; however, it is known to hover near palmetto stands, where large and dense colonies form when left undesturbed.

The leaves are about 1 inch long, narrow, dull green, and shiny with white hairs underneath.

The flowers are about 1.5 inchs across, five petals, wedge-shaped; many stamens. The flowers lasts only 1 day and produces many seeds. Flowers occur between May and July.

The generic name is derived from the Greek helios (the sun) and anthemon (flower). The common name relates to the ice crystals which form from sap exuding from cracks near the base of the stem in the late fall
