None [2].
Associated with clay soils [2] supporting valley and foothill grasslands, open areas of chaparral, cismontane woodland, coastal scrub, and occasionally vernal pools. Habitats near the coast below 600 meters [3].
Crassulaceae family [2]. Identification should be regarded with some skepticism because this species is very closely related to, and often confused with, Dudleya multicaulis (many-stemmed dudleya) [3]. Without careful attention to correct taxonomic verification, the wrong taxon might be targeted at the site.
Small herbaceous perennial succulent [1].
Blooms April-June [2].
Threatened by development, grazing, and possibly nonnative plants [2]. Detrimental edge effects, including recreational activities [3].
Numbers tend to fluctuate with rainfall [4].
