I love African Daisies...especially for my container gardening. They are an annual and come in such an array of different color combinations. .The flowers open fully only in direct sun, and they complete close each evening.
They love cool evenings and will bloom profusely when the temperatures fall down to the 70's. During periods of the summer when the nights are very warm, there will be a period of reduced blooms. When the nights cool off, they will perk back up and put on a fresh show.
