Coin-leaf willow

Coin-leaf willow (lat. Salix nummularia) is a miniature, creeping shrub species belonging to the Salicaceae family. Known for its prostrate growth habit, this plant is highly valued in horticulture for its ability to form dense, living carpets that mimic the natural alpine meadows of its origin.

The native range of this species extends across the harsh climates of Eastern Siberia, the Russian Far East, and parts of North America. It has evolved to thrive in tundra conditions and high-altitude rocky environments, where its low profile provides protection against biting winds and sub-zero temperatures throughout the year.

Botanically, the plant is characterized by creeping stems that root at the nodes. The leaves are small, rounded, and coin-shaped—a feature that provides its common name. The foliage is typically a vibrant green on top, often showing a glaucous, bluish-white tint on the underside, which adds texture to any garden design.

Cultivation requirements involve providing well-draining, moist soil that is slightly acidic. Being a sun-loving species, it requires ample direct light to maintain its tight, compact growth habit. Proper moisture management is critical; while the willow needs consistent water, it must never be allowed to sit in waterlogged soil, which invites root decay.

Economically and aesthetically, the coin-leaf willow is primarily used in rock gardens, scree slopes, and as a ground cover in alpine-style landscaping. Maintenance is relatively simple, focusing on weed control and occasional monitoring for pests like aphids or fungal issues like leaf rust, which can be mitigated through good air circulation and appropriate fungicide applications.

• Excellent winter hardiness.
• Fast propagation through stem cuttings.
• Low-maintenance growth habit.
• High aesthetic value in rock landscaping.
