General Culture: Click for monthly care information.
Grow in sandy, dry to medium moisture, well-drained soils in full sun. Tolerates drought and hot summers, but dislikes the high humidity of the St. Louis area. Avoid overhead watering to help prevent onset of fungal leaf diseases. Seed may be sown directly in the garden after last frost date or started indoors 6-8 weeks before last frost date for earlier bloom. Also may be grown in pots/containers.
Noteworthy Characteristics:
Rain daisy or weather prophet is one of several different tropical composites commonly called African daisy (see also Osteospermum and Arctotis). It is a tender annual that grows 8-12” (less frequently to 16”) tall, and features daisy-like flowers with white rays (tinged purple beneath) and yellowish-brown center disks. Flowers bloom freely from summer to fall in cool summer climates, but may slow down considerably in the hot and humid St. Louis area summers. Flowers close at night and on cloudy days or before rain (hence the common names). Narrow obovate to oblanceolate, dentate green leaves (to 3.5” long). Synonymous with D. annua and sometimes included in the genus Osteospermum.
Problems:
No serious insect or disease problems. Watch for leaf hoppers and powdery mildew.
Uses:
Mass in beds, rock gardens or borders. Containers.
