Dudleya

Morphological Summary

Dudleya is a genus of perennial rosette-forming succulents native to the Pacific coastline from southwestern Oregon to Baja California, Mexico, with the greatest diversity concentrated in California. Their rosettes bear lanceolate or spatulate leaves ranging from matte green to silver-grey or chalky white with a heavy pruinose coating, producing star-shaped flowers in yellow, pink, or red on branching floral stems. Species typically inhabit coastal cliffs, rocky outcrops, and stony chaparral slopes, tolerating salt-laden winds, prolonged drought, and extremely poor soils. Their ornamental appeal and high valuation in the Asian succulent market have made them the primary target of illegal poaching, prompting the passage of California law AB-223 (2021) to protect wild populations.
