This has become my favorite succulent. I first fell in love with it at the UC Berkeley Botanical Garden. When I found it at a local nursery a couple of years later, I jumped at the chance and bought it. It has been pest free and easy to care for. I grow it in a pot and it is thriving. Does anyone know how I can propagate it? I have found no information on that online. It doesn't seem to form rosettes.

I purchased one from Cottage Gardens of Petaluma (highly recommended, by the way) in a 4 inch liner about 2 months ago. The current spread of this plant is over 12 inchs and the new leaves are a stunning blue-white. It is my current favorite (changes all of the time). Easy to grow as we come to winter, I probably will not water it at all.

Native of Baja California's northwest Pacific coast and nearby environs. Two forms in nature and cultivation: one pale green and smooth, the other silver blue and covered with a fine powder. Both forms develop a (relatively) extended caudex with advanced age, covered tightly with dry leaf remains and flower stalks. Leave the dry leaves on the plant to avoid exposing the caudex and disfiguring the plant.

Like other Dudleyas, it tends to be most active during the winter, which is when it receives rain in habitat. Flowers in winter through spring attract hummingbirds. By mid summer (dry season) plants typically have shrunken up and slowed way down. Avoid overwatering at this time.

Grows best in strong light, up to day-long sun. (Typically found in exposed ... read more

this is a natural form of Dudleya brittonii found in nature so it not really a 'cultivar'. But it is seen far less often in cultivation simpy because it is less desirable, though it is still a striking and larger dudleya. This plant has no dusting whatsoever and leaves are almost shiny and more rubbery than it's white counterpart.

A nearly white plant, usually solitary and great accent for xeriscape gardens. Pretty hardy in So Cal with few areas it can't survive in, except shady, moist areas. Green forms of this exist as well... as do some suckering forms. Though rare and collector's items, the green ones rarely end up in cultivation.
