So distinctive is this species, that for a time it was placed in its own genus Idria. Endemic to central Baja California its upside-down-carrot-like stems are normally solitary but often branch higher up with age. These branches with succulent tissue and a flexible basket-like vascular network can droop during drought, then the tips grow upright again in wetter times. This can result in whimsically curly-cued branching patterns which are part of the charm of plants in habitat. These conditions are difficult to duplicate in cultivation, nevertheless, the otherworldly form of the plants at all stages of growth makes them desirable to succulent collectors. We offer seedlings selected for their especially plump egg-shaped caudexes. They were grown from seed set on plants growing at the San Diego Wild Animal Park which were harvested under permit to create the grove planted there. HBG 119760, $8.
