The paper assesses acclimatization success for 18 North American woody deciduous plants growing in the arboretum of Mountain-taiga station of the Far Eastern Branch of the Russian Science academy. according to N. a. Kokhno methods, acclimatization numbers are determined, which are the sum of growth indicators, generative development, winter hardiness and drought resistance. 13 species have an acclimatization number of 80-97 points and undergo full adaptation. 7 of them have an accelerated acclimatization, 6 species have a normal and slower acclimatization. 5 species have an acclimatization number of 72-76 points and are characterized by medium adaptation. All investigated plants are ornamental in different phases of seasonal development. The paper also shows an expedience of further works on reproduction and introduction of the studied ornamental plants of the North American flora into the culture.
