Named after Captain Meriwether Lewis of the Lewis and Clark Expedition, this species of Lewisia is a fascinating plant found clinging by a very stout taproot to rocky outcrops, wedged into crevices, and in cracks on canyon walls. The flowers with their pink and white candy-striping are charming and showy against the backdrop of a basal rosette of dark green leaves. This beautiful plant is a threatened species in northern California.
