Western thuja (Thuja occidentalis L.) as a representative of evergreen coniferous species is of particular importance in the landscape gardening of urbanized territories in Siberia. An integral assessment of the introduction prospects based on the study of winter hardiness, regularity of shoots growth in height and other parameters showed that Western thuja in the soil and climatic conditions of Krasnoyarsk belongs to a promising taxon (86 points out of 105). For the purpose of widespread use of the introduced plant in the landscape gardeningpractice, a method for increasing the rooting capacity of Western thuja green cuttings is proposed. Soaking green cuttings in a solution of indolyl-3-acetic acid with citric acid and adding nanoparticles of biogenic ferrihydrite doped with aluminum increases the rhizogenesis of the cuttings material by 10-20%.
