Britton's Dudleya (Dudleya brittonii) is a solitary or slowly-clumping succulent with a wide rosette of chalky-white leaves surrounding a thick basal stem. Stout silvery-white spikes arch upward and blush red as the clusters of yellow flowers begin to open in late spring to early summer.  This plant is also known as Giant Chalk Dudleya. It is native to coastal areas of the Pacific side of Baja California between Tijuana & Ensenada and on Isla Todos Santos where it grows on cliffs and hilly areas in lava rock and other very porous soils.

Plant in a well-drained soil in full sun along the coast. It needs protection from afternoon sun in hotter inland locations. This plant can tolerate garden conditions better than the similar looking Dudleya pulverulenta but it is still best to keep it plant dry in summer months and particularly avoid overhead irrigation during this time. This is a great plant for the rock garden, a crack in a rock or wall or in a container.  It can be propagated from leaf cuttings, seeds, or offsets.

The flowers attract pollinators such as bees and butterflies.
