Botanists have long been known that some of the trees are growing a variety of forms, including shrubs and even a miniature variety.One such species is the dwarf willow.
More precisely, it is not the name of the species, and many other wonderful trees, which we'll talk today.
Most of them grow in the Arctic Circle and at high altitudes.In the Alps, the dwarf willow was found at an altitude of 3.2 km.This tree is found even in the archipelago of Svalbard.
In the United States grows up to Labrador.All of this family of willow different attachment to wet places they prefer to grow along the coast, sometimes even in areas that are regularly surf rolls.
Almost all of their representatives so beautiful that immediately gained recognition among landscape designers.In particular, they are recommended to apply for green Alpine hills and rocky areas.
dwarf willow excellent resistance to freezing and the snow for a long stay because of its small trunks stelae close to the ground.
Buds oval up to 6 mm firmly pressed to the shoots.One shoots develop no more than 3-4 leaves.Stipules not.
The leaves of most species are characterized by their form broadly, they round the tip, or with a small recess, their length is rarely more than 25-27 mm.
In addition, young leaves are distinguished by the presence of "fuzz" on both sides, while the grown counterparts, it is saved only along the leaf cuttings.
Despite the love of good hydration, dwarf willow is very common on the rocky slopes, often grows on the border of rock fractures, especially preferring limestone rocks.Not bad makes acidification (and salinity, as we have said) soils.Lowered to the ground instantly shoots rooted.
In species that grow in different climatic zones, there are serious differences in the growing process.In mid-April buds dwarf willows in the Alps, and the beginning of May start other kinds of vegetation.
Despite the resemblance, these plants are very different from each other in the degree of pubescence of the leaves and young shoots, as well as the size of the trunk.So, S. reticulata, which grows in the Northern Urals, has a rather long shoots up to 25 cm and dark green leathery leaves.
Khibiny By the plants are dwarf willow spherical, shoots which do not reach a significant size.Alpine species even more petite.They retain the fluff on the underside of the sheet for a long time.
These shrubs grow very bad, so rooting best to use only the young shoots as stiff little root.It is best to take root and grow plants from the Northern Urals.For three years they reach the same magnitude as the Khibiny copies in 11 years.
Regardless of the species, the dwarf willow (which has a photo in the article) is extremely resistant to pests, frost and lack of nutrients in the soil.
