Guadalupe liveforever is a very rare, rosette-forming succulent native only to the rocks and islets around Guadalupe Island, off Baja California. Its key to growing is bright light, very sharp drainage and minimal watering, and many nursery plants sold under this name are actually a different species, Dudleya greenei.

About
Dudleya guadalupensis is a very rare species of succulent perennial plant in the family Crassulaceae commonly known as the Guadalupe liveforever. It is a rosette-forming leaf succulent, with foliage that is variously colored light green, green, and a waxy white. It is characterized by dense leaves that fold over the center in dormancy, a curving, sinuous flower stalk, and white, cup-shaped flowers. It is endemic to the rocks and islets off of Guadalupe Island, an isolated volcanic island in the Pacific Ocean located 241 kilometers off of the coast of Baja California.
How to grow it
Most of the examples of plants alleged to be this species in cultivation may be mislabeled. Noted Dudleya collector Paul Thomson observed that many of the plants in cultivation bear little resemble to actual D. guadalupensis plants. Reid Moran also notes that plants in the nursery trade labeled as D. guadalupensis are in fact D. greenei, a species native to the Channel Islands of California with a different chromosome count. Moran found that none of the collectors of the cultivated specimens could verify that the source was from Guadalupe Island.
Where it grows
Dudleya guadalupensis is native to Guadalupe Island and the surrounding islets. The type specimen originates from Islote Afuera (Outer Islet), collected by Reid Moran. On Islote Afuera, the plants are common from the inner slope of the crater to the upper valley. The plants there have uniformly light green foliage. On Islote Negro, plants have both green and farinose foliage, with the rosettes being less clustered and more solitary. The species is present on Islote Adentro (Islote Toro). Plants have also been spotted on Middle Rock and other islets off of the island.
