Arctotis is a genus of annuals and tender perennials that produce brightly colored daisy-like flowers. There are 50 or so species in this genus. Arctotis is commonly referred to as the African daisy.
Arctotis are natives of South Africa. They grow naturally in dry conditions producing rosettes of gray- to silvery-green leaves. Flowers are borne one per stem from midsummer to fall; they open wide on sunny days but close at night and sometimes on cloudy days. Flower colors include white, pink, orange, apricot, red, and terra-cotta; most are more deeply colored toward the center.

Arctotis Frequently Asked Questions
Q: How can I get my Arctotis–African daisy– to bloom?
A: Arctotis may not bloom if the weather is very warm and humid or if there is a sudden chill. Arctotis does well in warm, dry conditions. Make sure the soil is well drained and use a fertilizer that is higher in phosphorus and potassium than nitrogen such as 5-10-10.
Q: Can I sow Arctotis seeds directly outdoors?
A: Arctotis can be sown outdoors in early spring as soon as the soil can be worked, but you may have greater success if you start seeds indoors about 4 to 6 weeks before the last frost. Plants can go in the garden after the last frost.
