Sweet William is winter hardy to USDA Zones 3-9. This is a short-lived perennial wild flower that is perhaps best grown as a biennial. Many of the new cultivars will bloom the first year from wild flower seed if the seed is started early enough. Sweet William is best grown 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 reseed each year and remain in the garden for many years as if it were a long-lived perennial. Double-flowered forms will not come true from seed, however. Prompt deadheading of spent flowers (shear back large plantings) promotes perennial tendencies. wild flower seed may be planted directly in the garden in late spring for bloom the following year. Some nurseries sell seedlings in early fall that may be planted immediately for bloom the following year. Nurseries commonly sell plants in spring for flowering the same year.
