Dudleya pachyphytum (Cedros Island Liveforever) A ground-hugging slowly-clumping succulent to 1 foot tall by 2 feet wide with a thick basal stem from which form many branches bearing 5 to 10 inch wide rosettes of interesting leaves that are unlike all other Dudleya. These leaves are very thick, somewhat blunt at the tips and rounded on the edges and have a beautiful white waxy coating. In mid-summer appears the long inflorescence, slightly pink at the base but otherwise covered with the same white coating as the leaves and bearing tight cymes of pale green to whitish flowers. These flowers barely open but are decorated with the same white coating as with the inflorescence stems and leaves. Plant in a very well-drained soil in full sun to bright light - give some protection in inland hot sun. It grows well with winter and spring rains and, unlike many others in the genus, will respond well to regular to occasional irrigation in summer months. Hardy to at least 18 F (as it withstood this in our collection in 1990). This is a great plant for the rock garden, a crack in a rock or wall or as a container specimen. The name Dudleya is named for William R. Dudley (1849-1911) a botanist at Stanford University. The specific epithet "pachyphytum" was given to this plant when Reid Moran and Michael Benedict described it in May 1981 in the Cactus and Succulent Society of America Journal. It is an interesting specific name as it is the same name used for the genus of related plants from Mexico which gets its meaning from the Latin words 'pachy' mean "massive" and 'phytum' meaning "leaves" and is a fitting name as the leaves do resemble those of various species of Pachyphytum. Dudleya pachyphytum grows on steep rocky areas on north facing cliffs above 2,000 feet on the frequently foggy north western slopes of Cedros Island, located in the Pacific Ocean west of Baja California. This species was discovered only fairly recently because of the relative isolation of Cedros Island itself and because this northern area is a more inaccessible part of the island. Michael Benedict from the Santa Barbara Botanic Garden was the first to document finding this plant in 1971 but the plant he found was one that that had washed down the main northern canyon, Canada de la Mina. He returned in 1975 and 1977 to find plants along cliffs to the north and west of this canyon. In 1977 Alfred Lau and Antonio Garcia also discovered many plants of this species growing at the top of the ridge above of the Canada de la Mina and this discovery with excellent photographs of the plant were published in the Cactus and Succulent Society of America Journal in September 1980, before Moran and Benedict described it. There is an unfortunate story circulating that groups visiting Cedros Island in 2010 removed a large number of this species from their natural habitat. If this is fact and not rumor, we find this news very depressing and urge visitors to any natural habitat not to dig plants such as this from the wild. Our original stock plants of Dudleya pachyphytum came from Dylan Hannon who grew his plants from seed collected in 1978 by Mitch Beauchamp, before it was first officially described in 1981. Plants from later generations from this seed were distributed by the Huntington Botanic Garden's International Succulent Institute in 1998 as Dudleya pachyphytum ISI 98-40. Our current crops are plants from seed that we collect ourselves on our nursery site from these ISI plants we are growing as stock plants in our nursery.  This description is based on research and observations of this plant as it grows in our nursery, in our nursery garden and in other gardens that we visit. We also incorporate comments received and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Dudleya pachyphytum.
