SWEET WILLIAM SEEDS

Dianthus barbatus

Hardy biennal or short-lived perennial that may be grown as an annual if sown early enough in the season. Self-sows to the point of seeming reliably perennial in cold winter climates. This is a custom mix of solid, bicolor and double flowers in shades ranging from white to deep burgundy. Contains more diversity of color and form than any other mix available. Careful selection for preferred qualities will result in a unique blend that blooms each spring in perpetuity.

These seeds can be sown directly into the garden in early spring, but we prefer to start them in flats in late winter and transplant in the month before the last spring frost. Press seeds into moist soil and just cover with fine vermiculite. Mist generously and cover with plastic to maintain moisture. Kept moist and fairly cool (60°-65°F) in bright light most seeds typically germinate within a week or so. High temperatures will prevent germination so avoid heat mats and keep lights high above flats. Once seeds are germinated they prefer to grow in considerably cooler temperatures. Cool greenhouses are ideal but a cold shed or basement under grow lights works just as well. Pinch foliage once it is 2"-3" to encourage branching, and periodically thereafter to keep plants manageable and prevent flopping. Water regularly but allow the soil to dry slightly between waterings to encourage root development. Harden off and transplant into full or part sun in spring when nights are still quite cold but the soil is easily worked, even as early as you would sow peas and radishes.

Green foliage with flowers can reach over 2' in all directions. Space plants generously, at least 1' apart and even more in rich moist fertile soils. Transplants will usually bloom in the first year, but they may also wait to bloom in the second year. Cull plants just as flowers open if the color or form is not to your liking so that they may not cross with preferred plants. Allow the plants you do love to self-sow or collect seed to start indoors again the next season. We recommend the former, as self-sown seedlings are almost invariably healthier and more floriferous. Over time each garden will exhibit a distinctive population of plants curated by the gardener.

Sweet William flowers are edible and make for delightful desserts and crudités. These flowers also make fabulous bouquets if stems are cut while most buds are still unopened.

Packet contains around 300 seeds.
