Dudleya cymosa is native to my area, but is quite uncommon in cultivation. Most dudleya live in a seaside environment, but D. cymosa is much more of an inland species where the summer environment is quite harsher. I have found that at least small specimens are summer deciduous, dying back to a corm the size of a pea for the summer, to burst back to life when it cools off and rains in the fall. Thus they only have seasonal interest and many uncommitted gardeners would throw them out thinking they have died.

D. Cymosa is somewhat uncommon, but North facing slopes with extensive rock outcrops in the coastal ranges are likely to have them. Generally they grow where they get only a few hours of sunlight per day.

Dudleya cymosa should grow quite well in most low... read more

dudleya cymosa grows on rock cliffs along the ocean and inland. they are very beautiful relatives of echeverrias. their colors change throughout the year ranging from subtle to fantastic. they are easy, drought-tolerant plants that do great in containers and rock gardens and thrive under extreme heat and drought for short periods. they produce alot of very tiny seeds which germinate into plants that are almost invisible for their first year - and need to be protected during that time.
