Care
Light exposure
Choose a sunny or partially shaded location for optimal flowering. This alpine plant appreciates light but tolerates partially shaded areas well in hot climates. Avoid dense shade, which reduces flowering.
Soil and drainage
Clinopodium alpinum prefers well-drained, light soil that is slightly chalky or neutral. Poor substrate suits it well, mimicking its natural mountain habitat. Avoid overly rich soils, which promote foliage at the expense of flowers.
Watering
Water moderately, especially during the growing period. This alpine plant tolerates drought well once established. In pots, let the soil dry at the surface between waterings; in the ground, little supplemental watering is needed except during very dry summers.
Fertilizing
No fertilizer is necessary if the soil is of reasonable quality. A very modest application of compost in spring is sufficient. Excess nitrogen promotes dense foliage at the expense of flowering.
Pruning and maintenance
Prune lightly after flowering to maintain a compact shape and encourage branching. In late winter, remove dead or damaged stems. A simple spring cutback is usually sufficient for this low-maintenance plant.
Diseases and pests
Very robust, Clinopodium alpinum mainly fears stagnant moisture and poorly drained soils, which can promote root rot. Pests are rare. If problems occur, improve drainage and aerate the base of the plant well.
Did you know?
Alpine Calamint is one of many aromatic plants in the Lamiaceae family, traditionally used in herbal medicine in mountainous regions. Its Latin name "Clinopodium" literally means "foot bed" in ancient Greek, a curious denomination whose exact origin remains debated among botanists. This small, discreet but charming herbaceous plant has long interested alpine plant collectors for its remarkable hardiness.
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.
