Dudleya is a genus of succulent perennials, consisting of about 45 species in southwest North America. Many plants in the Dudleya genus were formerly classified as Echeveria. The fleshy and glabrous leaves occur in basal rosettes, in colors generally ranging from green to gray. The inflorescences are on vertical or inclined stems up to a meter high, but usually much shorter, topped by a cyme with alternate leaf-like bracts. Both the petals and sepals of the small flowers are five in number and fused below. Five pistils, also fused below, have 10 stamens arranged around them.
