Dudleya, or liveforevers, is a genus of rosette-forming succulents from southwestern North America, with about 70 species ranging from large evergreens to tiny summer-dormant plants. The key to growing them is sharp drainage and dry summers, as they are adapted to rocky outcrops and cliffs.

About
Dudleya, commonly known as liveforevers, is a genus of rosette-forming succulent plants in the stonecrop family, Crassulaceae, consisting of about ~70 taxa found in southwestern North America and Guadalupe Island. The genus is very morphologically diverse, with species ranging from large evergreen plants to tiny deciduous geophytic plants. The flowers of Dudleya have parts numbered in fives, with the petals arranged in tubular, star-shaped, or bell-shaped forms and, when fruiting, are filled with tiny, crescent-shaped seeds.
The genus evolved as neoendemics, from ancestors in the stonecrop genus, Sedum. The ancestors probably radiated southward from Sedum during the creation of the dry summer climate, in the California region, five million years ago. Early botanists classified the larger species as Echeveria and Cotyledon, while the geophytic species were placed under Sedum.
Where it grows
Dudleya species are widespread and diverse in their range, but are typically found in rock outcroppings, cliff faces, or road cuts, where their leaves help them store water in a setting too dry for most types of plants. Most are small and inconspicuous when not in bloom. The two predominant habitats where plants of this genera may be found are by the coast or mountains. Dudleya favor moderate temperatures, summer dormancy, winter precipitation, and rocky habitats, which means they may be found in diverse, disjunct locales from oceanic bluffs on the California coast to sky islands in Arizona.
