Red Sweet William has fragrant bright red flowers that bloom all summer. Perfect in containers or the front of your garden. Only grow to 8" tall. (Dianthus barbarini)
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
Dianthus is the botanical name of a great group of flowers that includes wild Sweet William, the pinks, and of course, the carnations. Some of the pinks have been in gardens since Elizabethan times, and of today the carnation is a mainstay of the florist trade. Dianthus species are not at all hard to grow, and once they're happy in your garden, they'll return every year with more and more color and fragrance.
Seeds? Yes, we have the meadow favorite, Wild Sweet William (Dianthus barbatus) in our wildflower seed department. It's a favorite biennial that creates waves of magnificent colors (several colors and bi-colors) in wildflower meadows. And its a snap to grow.
