Large, pure white flowers with yellow center. Blooms contrast nicely with dark, linear foliage. With reblooming and a high flower production, 'Gentle Shepherd' can put on a show for months. Blooms early to midseason. Very easy to grow and low maintenance. Tolerant against erosion, and makes a good rock garden addition. Grows in clumps and can be divided.
Plant in well-drained, fertile soil. Performs best in full sun to part shade. Deadhead flowers after bloom. Divide plant every 3-4 years in the fall or spring.
