Dudleya cymosa subsp. marcescens
A small, summer-deciduous succulent from California that forms a basal rosette, drops its leaves in summer, and blooms with yellow flowers in spring. It is native to shaded volcanic rock slopes and does best with sharp drainage and a dry summer rest.
Dudleya cymosa subsp. marcescens is a species of summer-deciduous succulent plant known commonly as the marcescent dudleya or marcescent liveforever. Throughout the months of spring, it is characterized by a bloom of small, bright-yellow flowers with 5 petals, tinged with orange or red. It is a leaf succulent with a basal rosette, with the foliage withering in summer, going completely leafless, a neotenous trait in the genus. This species is endemic to the exposed volcanic rock of the Santa Monica Mountains in California, being found on shady slopes and outcroppings. It differs from its local congeners with its deciduous habit, slender caudex, and narrower leaf shape, although it is superseded in some of these characteristics by Dudleya parva, growing 13 km to the north, which has even narrower leaves and is quicker to lose them.
This species is endemic to California in the United States, where it is found in the Santa Monica Mountains and Malibu Creek area. It is restricted to thin soils on exposed volcanic substrates, from 150 to 500 m (490 to 1,640 ft). Plants of this species are typically found on north-facing shaded slopes and outcroppings, growing with moss and lichens. The habitat of this species is threatened by growing degradation, and by disturbances caused from recreational activities, particularly in Malibu Creek State Park. These disturbances are often from people making graffiti and rock climbers, who tear out the moss and lichens vital to the habitat. Because of this, it is listed as a threatened species by the United States Fish and Wildlife Service.
