In the wild this plant is a shrubby perennial, but as an indoor plant it is best treated as an annual. It makes a colourful summer-flowering potted plant for the greenhouse or sunroom.
Dimorphothecas, or African daisies, are spreading plants, and this species will form a mound up to 12in/30cm high. The coarsely toothed oblong leaves, some 3in/8cm long, are aromatic, and the daisylike flowers, which open from early summer to fall, can be as much as 2in/5cm wide.
They are generally bright orange-yellow, sometimes with a purplish tinge at the base of the petals.
Recent hybrids have been bred in many different colors. Among the best are the compact ‘Salmon Queen’ with salmon pink flowers, the aptly named ‘Glistening White’ with 7-in/18-cm stems, and ‘Giant Orange’ (sometimes called ‘Goliath’) with larger than normal bright orange-yellow flowers.
