What is thuja?

Thuja, genus of evergreen coniferous trees of family cypress (Cupressaceae). Two species are from the North America, three - from East Asia. In dense forest it stands differ with the narrow pyramidal crone and can reach impressive height. Squamous microphylls, redolent at trituration, densely cover applanate plumose branches. Some decorative sorts with compact crone and slowed down growth, including dwarfish, weeping and poecilophyllous, are deduced.

Now passing along the street we quite often see very attractive and slender trees growing near the houses. They differ from well-known for us fur-trees and larches. So what are these trees? It is THUJA.

Thujas represent evergreen trees or bushes, with sweepingly-pyramidal crone form. All species of Thuja are psychrophile, but are not always cold-resistant. Seeds ripen in autumn in a year of flowering. At spring crops seeds are stratified within a month or presoaked in water within 12 hours, or held in damp sand, until turning up. Garden forms of thuja are cloned only with lignified and green shanks as the becoming of the garden forms is very insignificant by seed reproduction. Green shanks are taken with a heel from the young, well grown plants. Thujas are easy for buying and it successfully grows in the rich watered soils, need shading, especially at young age. Thuja takes scraping well out, therefore it is used in green hedges, avenues, in topiary art and in creation of boskets.

Thuja as a sort of trees, can transfer replanting enough well. Thuja possesses high gas-resistance. It allows to bed it out on especially air polluted plots. Thuja can often be seen on garden plots, near city houses. It is often created with thuja so-called live wall, allowing to be fenced off from city vanity and noxious fumes.
