The author presents the results of the ecological, biological and ornamental assessment of lilac species of different ecological and geographical origin (ARRIFCB arboretum) in the changed conditions of the north of the Central Chernozem Region of Russian Federation. The species have been selected which are the most resistant ones to the winter period unfavourable factors – S. amurensis, S. velutina, S. vulgaris, S. josikaea.

Phenological phases of the lilac development depend on climatic conditions as well as on the biological peculiarities of plants themselves. The researcher has established the sums of positive and effective temperatures in the main phonological phases.
