Swiss willow

Description

Salix helvetica, the Swiss willow, is a scrubby willow species found in the Alps (from 1700 to 2700 m) and the Tatras portion of the western Carpathians (from 1600 to 2000 m). It is a naturally dwarf, erect shrub, growing to 50 cm (20 in) tall and broad, with silvery undersides on the leaves, and silvery catkins appearing with the leaves. It has gained the Royal Horticultural Society's Award of Garden Merit. The willow genus or willow genus (Salix) is a genus in the willow family, and grows as trees, shrubs, rice or herbaceous dwarf shrubs. The trees in the genus are usually called willow trees, while the more shrub-like species are usually called willow. Otherwise, arrows are usually called the species that have flowering and leaf splitting at the same time, while species that bloom on bare twigs are called willow. The genus has over 400 species. The grayish bark of the wood is smooth or rough and with a wood that often has ridges under the bark. Its winter buds have a bud scales and the leaves are strewn, simple and notched or finely sawn. The willow is a two-story building with flowers gathered in axillary pendants. Fertilizers of willow species have been found in tertiary strata in Europe, Asia and in Arctic regions, and these older species are often close to now living tropical willow species with many stamens. In older Quaternary deposits, modern northern varieties of willow are beginning to emerge. Traces of willow have been found in Italy and in Europe's pre- and postglacial peat layers of several today alpine and arctic species such as dwarf willow, net willow and polar willow. Willow occurs mainly in temperate areas in the Northern Hemisphere. In 2009, according to the Swedish Board of Agriculture, there were 36 willow species in Sweden, most in the north. The most well-known species in Sweden are willow (S. caprea), gray willow (S. cinerea) and willow (S. fragilis). Knowledge is difficult to determine the species when hybrids occur. Several cultivated species have been naturalized, such as white willow (S. alba), red willow (S. purpure) and basket willow (S. viminalis). Locally, planting willow dikes has been common, mainly in Skåne where the trees are a hallmark of the landscape. In Skane, there is band willow, Salix amygdalina (district target:green willow) and band willow, Salix lanceolata.
