Dudleya virens (Alabaster plant or Island live-forever) is an uncommon species of perennial, succulent plant in the family Crassulaceae, native to California and Mexico, growing in Los Angeles County, the Channel Islands, and Guadalupe Island (where subspecies extima is endemic). It grows on rocky, coastal bluffs below 400 m altitude, and is listed as an endangered species.
The leaves are fleshy and strap-shaped, 8-20 cm long and 1.5-3 cm broad, tapering from the base (or from near middle) and are mostly green. They are arranged in a rosette. The flowers are white, with five petals 7-10 mm long; they are produced in April, May, and June. Hummingbirds visit the flowers for their nectar. It grows best in full sun or light shade inland, preferring well-drained soil.
