|DIMORPHOTHECA sinuata - African Daisy, Star of the Violet|
Asteraceae; native to South Africa.
Germination: For best results, sow indoors 4-5 weeks before planting outside, covering the seeds with four times their thickness in soil. Maintain a temperature of 68-70° F during germination, which takes 10-15 days. Sow in the fall for spring color in the greenhouse. The seeds are not long-lived and should not be stored. Or sow outdoors where plants are to grow when the danger of frost is past.
Growth: Plant after frost is past in full sun and light, sandy, well-drained soil. Plants prefer sheltered spots and areas where temperatures are cool. Remove spent blooms to encourage re-bloom. In the greenhouse, grow in an average potting soil kept evenly moist and in full sun. Night temperatures should be 45-50° F.
Appearance and Use: This annual, with daisy-like blooms for cutting, is grown in beds, borders, or greenhouses. Upright, it gets to 4-12 feet tall, with colorful 2 1/2 - 3 1/2-inch blooms. Borne from summer to frost, the blooms are white, yellow, pink, and salmon, with blue or lavender undersides and contrasting dark centers. They close at night. The leaves are fragrant, and 3 inches in length.
*Grown as an annual will overwinter in Zone 9.

"Digging up a mature clump of perennials, separating it into segments with new stems and roots and discarding the old core is an effective way to keep plants vigorous, free-flowering and disease-free," Adrian Higgins, The Washington Post Garden Book
