Very little is known about Dudleya blochmaniae ssp. blochmaniae, or Blochman's dudleya, but its close relatives, other subspecies of D. blochmaniae, have been considered for Federal protection. These species include the short-leaved dudleya (D. blochmaniae ssp. brevifolia) and the Santa Rosa Island dudleya (D. blochmaniae ssp. insularis). The subspecies of Dudleya blochmaniae are succulent perennials that have a rosette of leaves that sprout from a cormb. A member of the stonecrop family, plants produce white flowers with red or purple markings on short stalks.
