(Dimorphotheca sinuata) Annual. To 12 inches. Also called Cape Marigold, Namaqualand Daisy—South African native that’s well-known in California and other mild-winter climates, not so much elsewhere. African Daisy is scrumptious in mass plantings, along driveways or as filler between larger border plants or shrubs. Summer-long color in warm shades of yellow, orange, and salmon, down to true white! The brilliant flowers run about 2 inches in diameter, close demurely at night and on cloudy days. Thrives in heat. Perennial where winters are very mild.
