Uses
All species of Lewisia are edible. Lewisia rediviva has a large edible root and as a result became a food source for local Native Americans. The root is peeled before boiling or steaming; cooking the root reduces its bitterness.
L. rediviva has also been used for medicinal purposes; chewing the root was used to relieve a sore throat. It has also been used to promote milk flow during lactation.
For gardening, Lewisia species are usually planted in rockeries because this mimics their natural habitat. Rockeries also provide the free drainage that Lewisias need to prevent their roots rotting. They may also be planted in pots, though they need to be well drained and protected from sustained wet weather.
