Chalk dudleya (Dudleya pulverulenta) is a perennial succulent that grows from southern Monterey County to Baja California. Its leaves are wide, flat, and pale-green, and they form a rosette. In winter and spring, chalky, waxy stems emerge and give rise to flower clusters. The clusters open into many pointy, rosy-red flowers that hummingbirds love.
Chalk dudleya needs well-draining soil and looks great in containers, on rocky slopes, or in rock walls. Its rosette doesn't like pooling water, so plant it at an angle. This plant goes partially dormant in summer, with only a tiny area in its middle that appears alive.
Chalk dudleya is susceptible to aphid infestations, which can cause flower and rosette deformities. It openly hybridizes with several other species.
