Dianthus barbatus albus (White Sweet William) is an upright, bushy, biennial or short-lived perennial prized for its dense clusters of sweet-scented, fringed, pure white flowers from late spring to late summer. Attractive to bees, butterflies, hummingbirds and other pollinators, the blossoms are borne on stiff, erect stems above prostrate rosettes of wide, lance-shaped, dark green leaves. No cottage garden would be without this old favorite, but it has a place in every garden. Easy to grow, White Sweet William looks beautiful in the sunny border and makes attractive cut flowers.
