A Native Ground Cover That Thrives in the Shade Viola sororia, the Common Blue Violet, is a beloved East Coast native that spreads gently to form a lush, low-growing carpet under trees and in shaded borders. In early summer it produces cheerful purple-blue flowers that are a key nectar source for early pollinators and a host plant for fritillary butterfly caterpillars. Deer, rabbits, and groundhogs leave it alone.
