Lewisia is a genus of small succulent perennials from western North America, many grown in rockeries or pots. Key to growing them is sharp drainage and protection from sustained wet weather, since roots rot easily.

About

Lewisia is a plant genus, named for the American explorer Meriwether Lewis (1774–1809) who encountered the species in 1806. The native habitat of Lewisia species is rocky ground and cliffs in western North America. Native Americans ate the roots, which have also been used to treat sore throats.

Where it grows

Lewisias are naturally found in western parts of North America. In their native habitat of north-facing cliffs, lewisias are subject to extremes in weather conditions.

Uses

All species of Lewisia are edible. Lewisia rediviva has a large edible root and as a result became a food source for Native Americans. The root is peeled before boiling or steaming; cooking the root reduces its bitterness.
