Care
Light exposure
Trommsdorffia maculata prefers full sun exposure for optimal development and generous flowering. It tolerates partial shade but will produce fewer flowers. Avoid overly shaded areas that would slow growth.
Watering
Water regularly during the growth and flowering period, keeping the soil slightly moist but never waterlogged. Reduce watering in late autumn. Water at the base to avoid wetting the foliage.
Soil
This plant appreciates well-drained, slightly fertile and rather light soil. A standard garden substrate enriched with compost is sufficient. Avoid overly compacted or constantly wet soils that promote rot.
Fertilizing
Apply a balanced fertilizer once or twice a month during flowering to support flower production. Reduced application is sufficient; avoid excess nitrogen which would promote foliage at the expense of flowers.
Pruning and pinching
Pinch young plants to stimulate branching and obtain a more compact and bushy shape. Remove faded flowers regularly to extend flowering and encourage new buds to appear.
Pests and diseases
Watch for aphids and spider mites, particularly indoors or in warm conditions. Good drainage and sufficient air circulation reduce the risk of fungal diseases. Remove any affected plant quickly.
Did you know?
Trommsdorffia maculata is a relatively little-known South African native in Europe, but highly appreciated by Asteraceae collectors for its small delicate flowers with spotted patterns that give it its Latin name 'maculata'. This colourful herb was long confined to botanical collections before gradually reappearing in contemporary gardens seeking original varieties.
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.
