Care
Exposure
Plant wall fumewort in full sun or partial shade for generous flowering. It appreciates airy areas that prevent stagnant humidity. It adapts very well to low walls, rock gardens and sun-exposed wall crevices.
Soil
This plant prefers poor, rocky and very well-drained soils. It tolerates chalky and rocky soils very well. Avoid rich soils or those retaining water that would promote excessive growth.
Watering
Once established, wall fumewort requires little water. Water moderately during active growing periods, especially during prolonged droughts. In pots, reduce watering in winter and ensure drainage is perfect.
Fertilizer
No fertilizer is necessary on naturally poor soil. Excess fertilizer would make it invasive and reduce flowering. Let it feed on the natural resources of the soil.
Pruning and maintenance
Prune lightly after flowering to maintain a compact shape and encourage branching. Leave some flowers to set seed for natural self-seeding. Remove dried parts at the end of winter.
Diseases and pests
Very resistant, wall fumewort rarely suffers from pests. Powdery mildew may appear in very humid conditions; improve air circulation. Root rot occurs mainly with prolonged excess moisture.
Did you know?
The name "fumewort" comes from the Latin "fumus terrae" literally meaning "smoke of the earth," alluding to the delicate and cloudy appearance of its finely cut foliage. Historically, this plant was reputed in traditional herbalism for various uses, which explains its symbolic presence in medieval apothecary 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.
