Dianthus barbatus Nigrescens Group

Sweet William is an old-fashioned cottage garden plant that usually grows as a self seeding biennial. This taller strain produces a mound of bronzy-green leaves, bearing showy clusters of unique maroon-red to black flowers for several weeks. Excellent as a cut flower. Remove fading flowers to encourage more buds to form. Pruning plants back hard after blooming will encourage them to survive for another year. Self-sown seedlings may be moved in fall or early spring.
