Mountain anemone: complete guide

Mountain anemone grows best on well-draining soil rich in minerals and sand or gravel. It abhors heavy clay and permanent root moisture, so drainage attention is crucial for success. Position the plant in full sun to half-shade locations receiving at least four hours of direct sunlight daily. It also tolerates alpine shade beneath trees or rocky outcrops well. The ideal soil pH is neutral to slightly alkaline (6.5 to 7.5), so add lime to acidic soils if necessary. Mountain anemone is extremely cold-hardy to USDA zone 3 (down to minus 40 degrees Celsius), so even in severe continental climates the plant survives provided drainage is excellent. Water sparingly except during active spring growth; in summer and autumn the plant is naturally quite dry. Fertilization is rarely needed in nutrient-poor alpine soils; excess feeding causes more foliage and fewer flowers. A single application of slow-release mineral fertilizer in March suffices. Do not deadhead faded flowers unless you wish to prevent seed dispersal; many gardeners leave seed heads for botanical interest and self-seeding next season. Plants may be divided in early spring when new foliage emerges, though mature clumps prefer being left undisturbed as they dislike frequent disturbance. Use a sharp knife or spade to carefully separate the rootstock, ensuring each division carries at least two growth points or eyes. Transplant divisions immediately to their new prepared locations.
