This twinspur's rambling habit and dense flowering makes it ideal for brightening up those dull sections of your garden with a splash of bright colour and it has a long flowering period, which ranges from spring into winter (October to June).

Diascia mollis thrives in lightly sunny or semi-shaded positions. In the wild, it tends to grow along streams or in the moist shade of rocks or large grass tussocks. Plant it in a well-drained, nutrient-rich, loam soil and keep moist by watering regularly, especially in summer.

Although a very rewarding perennial, it is short-lived and will need to be replaced in the garden approximately every 2 years. The plants are semi-dormant in winter and are often lost if the soil is not sufficiently well drained.

Unless environmentally stressed, Diascia mollis is generally in vigorous growth and relatively pest free. Snails and slugs can damage small plants. Red spider mite, white fly and mealy bug can be troublesome pests which should be treated with a suitable insecticide, either organic or chemical, as soon as noticed.

Diascias should be regularly cut back, especially when they get straggly. Trimming will promote new growth and fresh crops of flowers. Established plants can regularly receive a good slow-release fertilizer to keep them vigorous and healthy.

Diascia mollis can be propagated by seed sown in spring. Lightly broadcast the fine seeds on the surface of the soil and keep protected from wind, in light shade, until the true leaf stage. Pot up and grow on until planting size. Diascia mollis is most easily propagated vegetatively from 50-60 mm softwood stem cuttings done in spring, which root quickly in a sandy or light potting mix without any special treatment such as underheating or rooting hormone. Plant rooted cuttings into small pots in a humus-rich, friable and well-drained potting mix. Sometimes stems will root where they touch the soil and are easily removed and potted up.
