The stamp art is a photograph of an orange African Daisy. The photo was shot from above and shows the detail of the central disk formed by tiny tubular florets surrounded by petal-like ray florets.
Native to southern Africa, Osteospermum – called the African Daisy – is widely available in U.S. nurseries and makes a gorgeous addition to any garden. The flowers open in the morning sun, with blooms in variety of colors, including purple, pink, yellow, orange, and white. Some of flowers have smooth, flat petals like typical daisy, while others have petals that each radiate out into a shape like spoon.
Where summers are cooler, African Daisies bloom abundantly from spring to fall frost. In climates with hot, humid summers, the flowers bloom well in spring to early summer, but the decline rapidly in high summer heat. Some varieties rebloom in fall when cooler temperatures return.
