Distribution and habitat
Lewisias are naturally found in
western parts of
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car ...
. 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 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
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals. The proces ...
.
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.
