Growing Tips
Sow seeds indoors 1/4 inch beneath the soil, 8-10 weeks before the last frost. Seeds will germinate in 14-21 days. Transplant outdoors once the plants have their second set of true leaves and the danger of frost has passed. Set plants about 6 inches apart (or into containers or hanging pots) in nutrient rich, well drained soil. Plants do best in partial shade.
