Sweet William is an old-fashioned cottage garden favourite that usually grows as a self seeding biennial. This dwarf hybrid strain produces showy, large clusters of fragrant flowers with cherry-red petals delicately edged in white, over compact bright green foliage. Terrific in containers and for edging borders. Developed to flower well even in the first year, then return for a second. 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.
