The success of plant introduction (transfer to new environmental conditions) is largely determined by their various biological features. This article analyzes the results of the introduction of several hundred species of herbaceous plants into the southern taiga of the Middle Urals (Ekaterinburg) and Western Siberia (Tomsk), as well as into some other introduction points of the taiga zone. The influence of the specificity of geographical distribution of species (chorological and zonal groups), their life forms, the pattern of seasonal development and phenorhythmotypes on the success of introduction was studied. General biological features of the species have been identified that contribute to their successful introduction into the southern taiga subzone, which suggests the stability and reliability of the established patterns. It has been shown that species distributed throughout Europe (except Southern Europe) and in Northern Asia are promising for introduction into these conditions. The introduction of forest (boreal and nemoral) species is proceeding successfully. The result of the analysis of the life forms of introduced species showed that hemicryptophytes are the most promising (according to the classification of K. Raunkier), herbaceous long-rhizome and creeping plants (according to the classification of I.G. Serebryakov) characterized by a high intensity of vegetative propagation. Species that regrowth early and begin flowering early during the growing season are also promising. The least successful introduction into the southern taiga is typical for Mediterranean and South-West Asian species, as well as for those distributed in the subtropical zone. Species with the life form of chamephytes (according to the classification of K. Raunkier) and subshrubs (according to the classification of I.G. Serebryakov) are of little prospectivity, as well as species characterized by late times of spring regrowth and the beginning of flowering.
