Objective – to identify and characterize the state of ontogenetic plant species of the genus Heuchera L. in terms of introduction. Material and methods. Investigated the ontogeny of int roduced plants H. chlorantha Piper, H. grossulariifolia Rydb., H. villosa Mich., H. sanguinea Engelm., which grow in the area of collectible National Botanic Garden behalf M.M. Gryshko NAS of Ukraine. Results. In the first year of life, the development of the studied species of this genus occur on a similar scheme. The differences at the species level appear in the calendar maturity developmental phases, their duration and morphological parameters vegetative organs. Plants polycarpic inherent in the development cycle, long-generative period in which they enter the second year of life. The longest age – a condition in which the plants are on the second, third and fourth year of vegetation – adult generative individuals. Starting from 5-6 years vegetation, the plants show signs of aging. In the 7-8 year plants come into subsenilе ontogenetic state. Conclusion. It was found that under conditions of Forest-Steppe of Right-Bank of Ukraine plants of the genus Heuchera species inherent latency, pregenerativе, generative and senile periods of individual development.
