|ZINNIA species - Zinnia|
Asteraceae; native to Mexico.
Germination: Best sown indoors, 4 weeks before last frost, at a temperature of 70-75°. Germination will occur in 5-7 days. They can also be sown outdoors, after all danger of frost is past in the spring.
Growth: Transplant when there are at least two sets of true leaves. Grow on in full sun at 60-65° days/55-60° nights. Space 6-12 inches apart in a rich, fertile, well-drained soil.
