Key Lime Pie – Adromischus cristatus – Crinkle-Leaf Plant

The leaves are thick and wedge-shaped with crinkled, wavy margins that look almost ruffled. It forms compact rosettes that cluster over time, creating a low, upright mounding habit in soft grey-green tones dusted with fine white hairs. Each leaf is plump and textured.

It is grown primarily for its foliage rather than for blooms. The clustering rosette habit means one plant gradually fills a pot with sculptural, layered growth that becomes more impressive each season.

You can leave it up to ten days without water. Move it outside in summer once nights stay above 50F, but always give it cover from rain to protect the leaves and roots. Rotate it regularly for even, balanced rosette growth. Leaf cuttings propagate successfully: gently twist a healthy leaf free, let it callous for a day or two, then lay it on dry succulent mix.

Water it deeply every 10-14 days in summer, pulling back to once a month in winter when soil dries completely.

Adromischus cristatus does best in fast-draining succulent or cactus mix blended with perlite or coarse grit.

It prefers temperatures between 50-80F and should be brought indoors before nights drop below 40F.

Adromischus cristatus is a slow grower needing only light, balanced succulent fertilizer once or twice during spring and summer.

It is hardy in USDA zones 9-11, tolerating brief dips to around 25-30F but performing best where winters stay mild. It grows outdoors year-round in California, Texas, Arizona, Florida, Hawaii, Nevada, Louisiana, Georgia, South Carolina, Alabama, Mississippi, and along the Oregon coast.
