Expert tips
The key tip
Diascia rigescens loves slightly enriched soil and regular watering during summer (it's not a drought-tolerant plant). Pinch young stems in June to densify and extend flowering.
The common mistake
Leaving it without water in July-August thinking its delicate foliage makes it drought-hardy: it wilts, stops flowering, and may not recover the following year.
The pro's trick
After the first flowering (July), cut back to half its height: a second abundant flowering appears in September-October.
Care
Exposure
This diascia thrives in full sun for generous and continuous blooming. It tolerates very bright locations and appreciates moderate warmth. Avoid partial shade, which would slow flowering and make the plant less compact.
Watering
Keep the soil constantly moist but well-drained during the growing and flowering periods. Water regularly in case of drought, especially in summer. Reduce watering in autumn. Avoid water accumulation that would promote root rot.
Soil
Prefer rich, light, and well-drained soil. A mixture of quality potting soil supplemented with sand or perlite works perfectly. This plant does not tolerate root asphyxiation.
Pruning and pinching
Pinch young shoots at the 3-4 leaf stage to promote branching and a bushy shape. Remove spent flowers regularly to extend flowering. Light pruning at the end of the season can revive the plant.
Fertilizing
Apply balanced or low-nitrogen fertilizer every 15 days during flowering. Excess nitrogen would favor foliage at the expense of flowers. Stop feeding in autumn.
Health and common problems
Watch for powdery mildew in humid and stagnant conditions. Aphids and spider mites can affect greenhouse plantings. Ensure good air circulation and avoid prolonged leaf wetness to prevent fungal diseases.
Did you know?
Diascia rigescens is native to South Africa and belongs to a genus whose flowers feature characteristic and colored nectary pouches, a remarkable botanical adaptation to attract pollinating insects. Although historically little known to the general public in France, it has gained popularity since the 1990s with horticulturists for its generous flowering and long-lasting ornamental qualities.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
