Dudleya crassifolia is a rare, drought-deciduous corm-forming succulent from one tiny sandstone bluff in Baja California. It goes dormant in dry periods and survives on its underground corm, so it needs a sharply drained, sunny spot and very little water.

About

Dudleya crassifolia is a species of drought deciduous, corm-forming succulent plant known by common name as the thick-leaf dudleya. It is an incredibly rare and cryptic plant native to one small locale less than a hectare in area on the Colonet peninsula in Baja California. It is threatened by urban development, including a proposed seaport. It is characterized by white, spreading flowers with leaf bases that are persistent on the stem. Although it did not receive as much media attention as the neighboring Dudleya hendrixii, it has been noted that the plant has several similarities to cryptic succulents like Anacampseros.

Where it grows

This species is endemic to Baja California in Mexico. This plant grows 7 miles south of the town of Colonet, on the reddish sandstone bluffs of a mesa. It grows in maritime chaparral, on a soil with iron concretions, similar to Dudleya brevifolia's habitat, which is also on a sandstone bluff with iron concretions. The entire locality where Dudleya crassifolia occurs is less than one hectare. It shares the general locality with numerous species of Dudleya, including other deciduous species like Dudleya hendrixii and Dudleya blochmaniae.
