Dudleya greenei is a rare succulent plant known by the common names Greene's liveforever, or Greene's dudleya. It is endemic to the Channel Islands of California, where it grows along the cliffs of four of the eight islands.
Dudleya succulents are a small genus; some look similar to the echeveria. The group includes 40 to 50 different types, with most native to Western U.S. states and Mexico. Some grow on the islands in those areas and possibly into S. America. Attractive, robust and long-lived, the Dudleya succulents often have a small, charming rosette. These occur on branches as they mature. This plant grows in a variety of shapes and has a range of habits. It may be branched or unbranched, and does not grow from its leaves. It can only propagate from seed, cuttings, or division, so not all Dudleya cultivars are available. “LiveForever” or giant chalk are common names for the plant.
