This tiny Lewisia grows to only 8” tall. From multiple rosettes of dark, evergreen leaves arise as many as eight sprays of striped or entirely rose-colored flowers. This species can live for an exceptionally long time, given excellent drainage and acidic, gravelly soil. In the wild, it grows on rocky slopes and sends a large taproot between the crevices in the rock to anchor itself. Native west of the Cascades in Washington and Oregon, Columbian Lewisia is hardy only between USDA zones 6-8. |
