Flower Seeds

Sweet William Flower seeds are also known as Dianthus, pronounced dy-ANN-thus, the botanical name being used almost as often as the common name when referring to this colorful, fringed and pleasantly spicy, aromatic biennial flower.


A biennial plant is defined as taking two growing seasons to complete its life cycle, though many of these, like Sweet William, are considered by some gardeners to be a perennial, these plants blooming and setting self-sowing seed in their second year, concentrating on growing foliage and roots during the first year, but perpetuating their growth in the following years. For the most part, you may see a few blossoms the first year, but the real reward will come in the second year. In subsequent years, the life-cycle will continue as the plants set seed, with the old plants dying out, being replaced by the newly seeded plants, resulting in that ‘perennial’ behavior we commented on earlier, as well as an always-blooming flower bed or border after the third year.


As all blooming flowers expend a lot of energy, we recommend regular feeding with Jungle Flora or Espoma Flower-tone®, both of which are approved for organic gardening and are safe for your family, pets, livestock and water habitats, as well as being specially formulated for blooming plants.


Each order of our fresh Sweet William seeds is filled by hand, put into a resealable plastic bag and then placed into a labeled seed packet. It is our goal to provide our customers the best in freshness and quality.
