Summary
Britton's chalk dudleya is a drought-tolerant evergreen succulent native to the Baja California coast, typically forming a solitary large rosette with chalky white, waxy-coated leaves; rosettes reach about 12–18 inches in diameter, with leaves about 10 inches long, and yellow flowers on pinkish-red stems bloom in spring to early summer. It grows on cliffs and rocky outcrops in well-drained soils.
In cultivation, it prefers well-drained sandy or rocky soil, full sun to partial shade, and very low water; avoid overhead watering to protect the white coating, and it is well suited to rock gardens or containers; propagation is possible by offsets or seeds.
