Lewisias are herbaceous perennials native to north facing cliffs in western North America.  They are members of the Montiaceae, a family that also includes Claytonia and purslanes.   This cultivar is clump-forming, evergreen and grows up to 6″ tall.  It forms rosettes of spoon-shaped dark green leaves that are fleshy, waxy, and up to 3″ long.  In late spring and summer loose cymes of conical, purple-pink flowers with magenta veins appear.  Plants are best grown in a wall crevice or scree but is also a good choice for alpine and rock gardens.  They grow best where summers are cool.   The genus name, Lewisia, honors the American explorer Meriwether Lewis  (1774 – 1809) of Lewis and Clark fame.  Lewis discovered the first Lewisia in 1806.
