One of the most popular plants used in landscape design is the prickly spruce "glaucus globus". This plant has been known since 1937, when it was bred selectively from the seeds of spruce spruce. In 1955, the plants first went on sale, after which they became regulars in city parks, gardens and squares.
Spruce "glauka globosa" is widely used for decorating
city landscapes by landscape designers of Russia, Poland, Ukraine, Belarus, Lithuania, Estonia, Latvia. It is often an adornment of the central and honorable places of the city - alleys and parks of Glory. The blue beauty, unlike
deciduous trees, pleases the eye of urban residents throughout the year, giving the scenery splendor.
The prickly spruce "glaucus globus" is a dwarf tree, in the first years of life it is a plant with a spherical crown. It does not have a distinct trunk. Only after about 12-15 years, the main shoot appears, which forms the triangular shape of the spruce "glaucus globosa", and it changes the spherical view to a pyramidal. If the plant is not trimmed, then in its entire life it reaches growth of no more than five meters, has a triangular crown up to three meters wide at the base. However, it is the shape of the ball that is most popular and most often used in landscape design. This form is easily achieved, since the prickly spruceous “glaucus globus” spruce perfectly lends itself to a haircut, for which it is loved by designers.
Considering that the tree grows very slowly, growing about 8-9 centimeters per year, the shape that was given to it during cutting will remain for a long time. This plant lives up to 500 years. The needles about one centimeter long are very densely located on the shoots, so the tree not only has an elegant blue color, but also very fluffy. Elongated cones form on the branches, which resemble New Year's decorations and give spruce additional elegance.
Landing and care
Considering that this plant is an excellent decoration even for small household plots, spruce prickly “glaucus globosa” is always on sale in specialized stores. The tree is not particularly demanding on the soil. The crown of such a decorative Christmas tree does not break under the weight of snow. Spruce is frost-resistant, resistant to city dust, dirt and soot. Seedlings are best purchased already prepared for planting, but you can grow a tree yourself by planting seeds. However, there is a possibility that the grown plant will lose its magnificent silver-blue color - it remains only in half of the seedlings grown from seeds. The tree does not require special care and top dressing, but it is still recommended to clear the crown of snow in winter in order to avoid the formation of ice on needles, as well as wash the plant during the summer period from dust in order to maintain its decorative blue appearance. Prickly spruce "glaucus globosa" can be attacked by pests such as spruce aphids, spider mites, bark beetles, spruce leaflets. Special means of protection and constant preventive treatment of the plant will help to get rid of them.
