Crocanthemum
Also called Rushrose, Frostweeds, Rockrose
Crocanthemum is a genus of flowering plants in the family Cistaceae. They are native to both North and South America where they are widespread. The common name frostweed relates to the ice crystals which form from sap exuding from cracks near the base of the stem in the late fall.
Crocanthemum are herbaceous perennials or subshrubs with alternate leaves. With the exception of species in California, they generally produce two types of flowers: showy, yellow chasmogamous (cross-pollinated) produced earlier in the growing season, followed by cleistogamous (self-pollinated) flowers that are smaller and lack petals. All species of Crocanthemum are fire tolerant and are found in open habitats.
