Sweet William, Holborn Glory (Organic)
Dianthus barbatus. Biennial / Perennial in zones 3-9.
Dark pink and white, candy striped flowers. Small, 1″ wide, single blooms appear in saucer-sized clusters atop 2′ tall, sturdy stems. The flowers bloom over a long season without deadheading and are highly desired by butterflies and bumblebees. If the plants are cut back low to the ground midseason, they may produce a second flush of flowers. Makes a good, long-lasting cut flower. This classic variety dates back to the 1920s. Deer resistant. Hardy biennial or short-lived perennial.
Sow indoors 8 – 10 weeks before last frost for summer blooms, or late spring for blooms early the following year. Transplant to 12” centers. Biennial or short-lived perennial grows well in full sun to part shade. Deadhead to prolong bloom and limit self-seeding.
Collect seeds from seed heads that are fully dry. Thresh by hand; winnow or screen to clean. Some cross-pollination may occur, isolate from varieties of the same species by 1/4 mile.
