The fresh bark of all members of this genus contains salicin[9], which probably decomposes into salicylic acid (closely related to aspirin) in the human body[8]. This is used as an anodyne and febrifuge[9].

Stems are very flexible and are used in basket making[10][11]. The plant is usually coppiced annually when grown for basket making, though it is possible to coppice it every two years if thick poles are required as uprights. Trees can be planted in shelter-belts for protection against the wind[3]. The extensive root system of this plant is good for binding sandy soils[2].

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - must be surface sown as soon as it is ripe in late spring. It has a very short viability, perhaps as little as a few days. Cuttings of mature wood of the current year's growth, November to February in a sheltered outdoor bed or planted straight into their permanent position and given a good weed-suppressing mulch. Very easy. Plant into their permanent positions in the autumn. Cuttings of half-ripe wood, June to August in a frame. Very easy.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Succeeds in most soils, including wet, ill-drained or intermittently flooded soils[1][2], but prefers a damp, heavy soil in a sunny position[7]. Rarely thrives on chalk[7]. Very wind-resistant, tolerating maritime exposure[3]. Hybridizes freely with other members of this genus[7]. Although the flowers are produced in catkins early in the year, they are pollinated by bees and other insects rather than by the wind[2]. Closely related to S. daphnoides[7] and considered to be a part of that species by some authorities[2][4]. Some named forms have been developed for their ornamental value[6]. There are also named forms cultivated for basket making[10][11]. Plants in this genus are notably susceptible to honey fungus[7]. Dioecious. Male and female plants must be grown if seed is required.
