Lewisia rediviva is the
Bitterroot of Lewis and Clark fame. Lewisia rediviva has a wide
range extending from British Columbia through Montana where it is the
state flower and on to Southern California. Lewisia blooms in
the Spring and then goes dormant. Excessive Summer water without
perfect drainage is often the end for this plant. Lewisia is often a
gorgeous addition to the rock garden and a number of hybrids are
periodically available at various nurseries.
