Zoom To My AddressZoom To California Estimated Plant Range

About Coast Dudleya (Dudleya caespitosa) Dudleya caespitosa is a succulent plant known by several common names, including sealettuce, sand lettuce, and coast dudleya. It is endemic to California, where it grows along the coastline from San Francisco to Los Angeles. This dudleya starts from a rosette up to 20 centimeters wide, containing up to 30 leaves. The leaves are fleshy, pale green, and cone-shaped to oblong, one or two centimeters wide and almost a centimeter thick. The stem is a caudex which grows erect up to about 20 centimeters in height before branching into the flower cluster. Its color is variable, from green to red and yellow shades. At the top is a tall flower cluster which may hold 10 or 15 flowers on each of several branches. The flowers are bright yellow with pointed petals.
