Care
Exposure
Place your stinking aster in full sun or partial shade to encourage generous flowering. It tolerates shaded positions well but will flower less abundantly. Avoid areas that are too hot and dry in Mediterranean climates.
Soil
This plant prefers well-draining, chalky or neutral soil, and isn't afraid of poor or stony ground. Improve drainage in heavy or clay soils to prevent root suffocation. It adapts to lean conditions, making it interesting for rock gardens or dry gardens.
Watering
Water regularly during growth and flowering periods, keeping the soil slightly moist without excess. Once established, the plant tolerates moderate dry periods. Reduce watering in winter when the plant is dormant.
Fertilizer
Enrich the soil with organic matter (compost) at planting time. Light application of balanced fertilizer in spring supports growth and flowering, without excess that could favor foliage at the expense of flowers.
Pruning and maintenance
Remove spent flowers regularly to extend flowering and prevent excessive self-seeding. Cut the clump to ground level in late autumn or early spring. Prune lightly after flowering if you wish to encourage a second flush of blooms.
Diseases and pests
Stinking aster is generally robust and rarely affected by diseases if drainage is adequate. Watch for powdery mildew in overly humid or confined conditions. Monitor for slugs and snails in spring, especially in damp soil.
Did you know?
Stinking aster owes its specific name 'foetida' to the unpleasant smell released by its leaves when crushed, a characteristic common to several Asteraceae species. Despite this unattractive scent, its small butter-yellow flowers attract butterflies and bees, making it an interesting ally for pollinator gardens.
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.
