Cultivation Details

Succeeds in most soils, including wet, ill-drained or intermittently flooded soils[, ], but prefers a damp, heavy soil in a sunny position[]. Rarely thrives on chalk[].
Hybridizes freely with other members of this genus[]. Although the flowers are produced in catkins early in the year, they are pollinated by bees and other insects rather than by the wind[].
Plants in this genus are notably susceptible to honey fungus[].
The root system is rather aggressive and can cause problems with drains[]. It is best not to grow this species within 10 metres of buildings.
A dioecious species - both male and female forms must be grown if fruit and seed are required.

Edible Uses

Growing in harsh and difficult environments, as many willows do (they can be found within the arctic circle, on mountains and even in the desert), Salix species have often been utilized as an emergency food source. They are, indeed, often a highly favoured food source for birds and mammals and, whilst few species would lay claim to culinary excellence for humans, the young shoots and inner bark are both edible eaten either raw or cooked[].
We have no specific information for this species, but the inner bark can be eaten fresh or it can be dried, ground into a powder and then added to cereal flour for use in making bread etc. It has a very bitter flavour, The young shoots are also somewhat bitter and not very appetizing - unless you are really hungry of course![].

Medicinal

The bark, twigs, leaves, leaf buds, and flower buds of all Salix species contain phenolic glycosides, particularly salicin and salicortin (which breaks down when the plant material is damaged to produce salicin). The quantity of these compounds can vary greatly between species, and even within geographical races of the same species. Taste is a simple test to ascertain levels of these compounds - the more bitter the flavour, the more compounds it contains[].
Salicin has several valuable medicinal properties. In particular it is an effective antiinflammatory and pain reliever, and is also a valuable febrifuge[].
Modern medicine has used salicin as a pathway to producing the common pain reliever aspirin and, until a totally synthetic pathway of producing the medicine was discovered, several Salix species were harvested on a commercial basis to obtain salicin.
Many Salix species have a history of traditional use (not always documented). All parts of the plant can be used, but the bark is more commonly employed. Their pain-relieving and antiinflammatory properties make them useful in the treatment of verious conditions including headaches, neuralgia and joint pains, whilst they can also be very helpful in the treatment of fevers[, ].

Other Uses

The stems are very flexible and are used in basket making[, ]. 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.

Propagation

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. This is a hybrid species and it will not breed true from seed.
Cuttings of mature wood of the current year's growth, late autumn to late winter 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, early summer to August in a frame. Very easy.
