Dudleyas, one of the signature native succulents of the Californias, are popular regionally because they are so practical in the Mediterranean, dry-summer climate. They may be less well known outside the area, in part because of their preference for dry summers and mild, wet winters. But they can thrive anywhere if you can provide strong light, mild temperatures, excellent drainage, and regular water when the soil is dry. + Show More

In mild coastal climates, Dudleyas enjoy plenty of exposure, up to day-long sun, especially the powder-dusted species. They are generally salt-tolerant and well-suited for oceanside gardens. Where summer heat is an issue, they will require some protection, but strong light is important for health and proper form. Dudleyas prefer excellent drainage and enjoy regular water during their period of active growth (fall through spring). But do not mistake summer dormancy for thirst -- it is quite the opposite. + Show More

Three factors are important in arriving at an accurate identification of Dudleya species. (1) Knowing the geographical origin of a plant will help reduce the number of options to choose from. (2) Seeing the flower will allow you to place the plant within a subgenus (based on shape), and in some cases tell you the species (based on color). Some flowers also have an informative odor. (3) Observing the rosette itself, to see whether stems branch, what color and shape the leaves are, and if they die off in the summer, will also help narrow the options. + Show More

Dudleya seeds are small, almost dust-like, but seedlings can be quick (1-2 years) to grow full sized rosettes. Hybrids are occasionally seen where two species bloom together. The species which branch can be easily propagated from cuttings in the fall or winter. The species which do not branch can be forced by coring.

No Dudleyas outside the Hasseanthus group can be propagated from leaves. That group is said to bloom at 5 months of age with good greenhouse care, and lose its living leaves in the spring. The other plants in the genus may bloom within their first year from seed, provided nursery care.

Dudleya is related to other New World Crassulaceae including Echeveria, which is separate geographically (found on mainland Mexico and parts south, not on the peninsula of Baja California). It may be difficult to distinguish the two genera without floral features. Echeveria flowers are always tubular, while Dudleya flowers may be tubular, flat, or cup-shaped.
