Salix alaxensis

(Andersson) Coville

Salicaceae


The genus Salix, as recognised in 2019, is comprised of probably more than 300 distinct species (over 500 if you also accept hybrid species). Many of these species are very similar, sometimes being separated as much by native range as by any other characteristic. Hybridization between species is common, when this is coupled with the high genetic and morphological variability within many species, and different levels of ploidy, the complexity of this genus is clear.
Misidentification of specimens is not rare, even amongst botanists, and many records of plant use will often equally apply to one or more related species that were not seen as distinct when the report was made. Equally, several species not included in the database will be found to have a range of these uses. In general, all species in the genus have medicinal uses, especially as antiinflammatories, analgesics and febrifuges, they can all serve as emergency foods, many of them have flexible stems and can be used in basket making, and many of them can be planted in moist to wet conditions in order to stabilize the soil and improve wildlife habitats.

Cultivation Details

Salix alaxensis is a very cold-hardy plant, able to tolerate temperatures down to around -35°c when fully dormant.
Salix species generally require a sunny position and abhor dryness at the roots. This species typically occurs in slightly acidic to mildly alkaline mineral soils that are aerated, relatively nutrient-rich, and well to moderately well drained[

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[

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[

Propagation

Willow seed is very small and light, and has a very short viability, perhaps as little as a few days in some species. It must be surface sown as soon as it is ripe. In nature the seed only germinates in disturbed soils in an open situation. In nursery conditions, sow the seed in a tray in a moderately sunny position and keep the soil moist. Germination is usually quite rapid - prick out the seedlings into individual pots when they are large enough to handle and grow on until large enough to plant out. Plants generally establish better if planted out whilst quite small.
Cuttings of mature wood of the current year's growth or older can root at almost any time of the year, though late autumn is considered best as this produces a better balance of root and stem growth the following spring[
