These succulent beauties grow on the West coast from Oregon to the tip of Baja California in a wide range of habitats and microclimates. They face challenges hanging on to cliffs, being trampled on mesas, and lasting through the summer dry season. Development, fires, poaching, and climate change present additional threats. Like many succulents, they grow in somewhat extreme places.
