Care
Exposure
Mountain clover thrives in full sun or partial shade. It appreciates an open exposure with good air circulation. Avoid dense shade, which would slow its growth and promote stagnant moisture.
Soil
Prefer well-drained and light soil, ideally calcareous or neutral. This plant tolerates poor and rocky soils, making it perfect for rock gardens or difficult spaces. Avoid clay and permanently damp soils at all costs.
Watering
Once established, mountain clover is very tolerant of drought. Water moderately when planting and during the first few weeks. During dry summer periods, occasional watering is sufficient; the plant resists well thanks to its deep root system.
Pruning
No pruning is truly necessary. Remove spent flowers to encourage prolonged blooming. You can lightly cut back the plant after flowering to maintain a compact shape and promote denser branching.
Fertilizer
Like legumes, mountain clover fixes atmospheric nitrogen and needs no nitrogen fertilizer. Naturally fertile soil is quite sufficient. A light application of compost in spring can boost overall vigor but is not essential.
Diseases and pests
This robust species is rarely affected by significant diseases or pests. Powdery mildew may appear in very humid and poorly ventilated conditions, which emphasizes the importance of good exposure. Proper drainage is your best prevention.
Did you know?
Mountain clover is a quiet ally of alpine ecosystems: its nodular roots form a bacterial symbiosis that naturally enriches the soil with nitrogen, benefiting the entire surrounding plant community. Historically, inhabitants of mountain regions have long valued it as a hardy fodder crop for high mountain herds.
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.
