Grey willow

Grey willow (Latin Salix atrocinerea) is a deciduous shrub or small tree belonging to the Salicaceae family. It is recognized for its robust growth habit and ecological resilience, making it a valuable crop for sustainable land management and renewable energy production.

The species is native to Western and Southwestern Europe, including the Atlantic coastal regions. It thrives in temperate, oceanic climates and is typically found in damp, marshy habitats, riparian zones, and nutrient-rich peaty soils, demonstrating a high tolerance for waterlogged conditions.

Botanically, Salix atrocinerea is identified by its greyish-hairy young shoots and elliptic to obovate leaves. The lower leaf surface is characteristically pubescent, which provides a distinct visual contrast. Like other willows, it is dioecious, producing catkins in early spring that serve as a crucial nectar source for early-season pollinators.

Cultivation requirements focus primarily on water availability. While the plant is undemanding regarding soil nutrient content, it performs best on moisture-retentive, slightly acidic soils. Agrotechnical management involves dense planting configurations using high-quality cuttings, followed by systematic coppicing cycles to maximize biomass yield for industrial or aesthetic purposes.

The economic utility of the grey willow spans from traditional basketry and weaving to modern bioenergy applications. Because of its vigorous root architecture, it is also extensively employed in landscape engineering for bank stabilization, erosion control, and the purification of contaminated wetlands through phytoremediation processes.

• Excellent tolerance to anaerobic soil conditions.
• High potential for short-rotation coppice (SRC) biomass.
• Effective erosion control in riparian zones.
• Significant value for early spring biodiversity.
