Sweet William Mixed Flower Seeds

Sweet William Mixed Flower Seeds (Dianthus Barbatus) Perennial, Wildflower. 

Minimum 25 seeds per package.

There is no disappointment with this wild flower seed! It is winter hardy to USDA Zones 3-9. This drought tolerant Dianthus Sweet William mix is a short-lived perennial wild flower seed that is perhaps best grown as a biennial. Many of the new cultivars will bloom the first year from wild flower seed when the seed is started early enough.

Sweet William flowers are grown best in deep, organically rich, well-drained soils in full sun, but generally appreciates some light afternoon shade in hot summer climates such as the South. In optimum growing conditions it will re-seed each year and remain in the xeriscape garden for many years as if it were a long-lived perennial.

Prompt deadheading of spent flowers (shear back large plantings) promotes perennial tendencies. Sow the flower seeds directly in the garden in prepared soil after danger of frost has passed.
