NEW DECORATIVE FORM OF SIBERIAN SPRUCE (Picea obovata Ledeb.)
The description of decorative shapes of spruce used for landscaping in the Russian Federation made. It is noted that copiesof the evergreen species of the genus Picea allow you to create not only avenue planting, but also to shape the landscape groupsof various sizes. High polymorphism of spruce (Picea abies (L.) H. Kast) enables the use trees with the original crowns in planting.Has proven himself in the greenery plantings such forms as: P. abies Acrocona, P. abies Virgata, P. abies Cranstonii, P. abiesPendula Major, P. abies Frohburg , P. abies Formanek. Great interest for gardening are dwarf forms spruce P. abies Barryi,P. abies Push, P. abies Wills Zwerg. Significantly smaller form diversity characterized Siberian spruce. Siberian spruce has beenmuch less polymorphism and has only two described forms – blue Siberian spruce (P. obovata var. Coerulea Malyshev) andPechora spruce (P. obovata ssp. Petchorica Govor), which are not widely used in the practice of gardening. Therefore, considerableinterest is detected new decorative form of Siberian spruce discovered on the territory of Yegorshinskoe forestry of theSverdlovsk region. The observed tree is unusual for eating habit and has a columnar shape of the crown, the branches numerousshoots are firmly pressed against the trunk, directed downward spiral. Because the shape of Siberian spruce, discovered in theUrals region, has no name, we propose to call it the outline of the crown and at the place of discovery. For example, Siberianspruce Fastigiata Ural (P. obovata var. Fastigiata Uralica Opletaev).
Siberian spruce, form diversity, vital form, narrow columnar shape of the crown, drooping crown shape, spiral branching, Picea obovata Ledeb. Fastigiata Uralica Opletaev.
