Dia­bunda Mix

Sweet William Seeds

Diabunda Mix is an exceptional Sweet William hybrid: it flowers the first year in bright shades of red, red picotee, pink pearl, rose, purple, and purple picotee. Branching from an early age, Diabunda Mix forms attractive 8-10 in. tall, 10-12 in. wide plants. All colors in the mix are uniform in plant size and time of bloom. Diabunda Mix Sweet William puts on a dazzling show in beds, borders, or containers.

Unlike conventional Sweet William plants, Diabunda Mix is nearly day-length neutral, meaning it is capable of blooming in spring, summer, and fall. Furthermore, compared to other Sweet Williams, its flowers are larger and are held at the top of plants where they can be more easily seen.

Diabunda Mix Sweet William plants do not require deadheading. New foliage and flowers quickly cover the old blooms. In all but the hottest climates, the first flush of flowers continues for about 5 weeks. Cut plants back, and within 2-3 weeks they will bloom for another 4-5 weeks. Diabunda Mix can be overwintered like pansies, producing extra-early spring flowers. Winter hardy to zone 5.
