Dodecatheon clevelandii appears to be the only species in the genus that is adapted to cultivation in Southern California. It is well suited to container cultivation in small pots-- a 4" pot is sufficient for a single plant-- in a range of soil types such as "peatlite" (peat + perlite), a sandy pumice mix, etc. Although the rootstock is only a slender taproot it persists over the summer in perfectly dry soil. In other words, it can be grown like a Romulea or a Massonia. The leaves appear in winter and flowering typically begins in February. It is one of the prettiest of the small winter geophytes and individual plants easily persist for 20 years or more. As indicated in this thread, the seeds last for 10-20 years under standard refrigeration. Over its wide geographic range there is appreciable variation in plant size, leaf appearance and flower color.
