Sweet William Double Blend HEIRLOOM Seeds

Sweet William Double Blend HEIRLOOM Seeds

Dianthus barbatus

Item #1087

Biennial. Charming large clusters of edible, double flowers in a myriad of colors, and one of the longest lasting cut flowers available! In the garden, butterflies and bees love the sweet and spicy scented flowers. As a biennial, Sweet William forms a lovely plant the first year, then flowers the second. In mild climates, plants may return the following year. However, for the best flower production, we recommend reseeding every year so you'll be sure to always have flowering plants. If flowers are left on the plant, it will reseed readily, and is always a welcome garden guest. Biennial in USDA zones 3-9.
