SOWING: Transplant (recommended) - Sow 4-5 weeks before last frost. Transplant out after last frost. Sow several seeds per cell or pot. Do not cover as seeds require light to germinate.

In warmer climates, sow midsummer to late winter for blooms that will last until June. Press seed lightly into surface. Thin when seedlings have first true leaves. Where winter temperatures drop below 28°F (-2°C), sow seeds in spring as soon as the soil can be worked.
