Seed may be sown directly in the garden 1-2 weeks before last frost date or started indoors 6-8 weeks earlier. Pinch stems of young plants to promote bushiness. Deadhead spent flowers to prolong bloom. Plants sometime struggle in hot summer climates such as St. Louis, and may temporarily stop blooming in the heat of the summer.
