Ontomorphogenesis of Scopolia carniolica Jacq. in natural conditions in Ukraine and also in conditions of culture in M.M. Gryshko National Botanical Garden is investigated. Features of the structural organization of shoot’s system, forming of shoots, location of flowers and forming of hypogeal rhizome of individuals of S. carniolica are described on different phases of ontogenesis. Big vital cycle of investigated species probably lasts more than 30 years and includes 4 phases and 9 age states. Specified diagnostic features of age states are presented. It is founded that individual of pregenerative phase differ morphometric parameters of shoot’s system, young, mature and old generative individuals – different namber of metamers of vegetative zones, the degree of branching of floral zone, capacity of development of aboveground and underground sphere. Phases of morphogenesis of individuals are determined: the primary shoot → primary (uniaxial) sympodium → diffusely branched sympodium, loose bush → autonomous particle as a part of diffuse clone.
