The research objective was to study the fea-tures of cultivation of the genus Dracocephalum moldavica L, new to Central Yakutia for further in-troduction as a medicinal and ornamental plant. In Yakutsk botanical garden the samples of the plant of Dracocephalum moldavica L, family clear water, new to Central Yakutia, were tested. Dracocephalum moldavica L. is the plant applied in medicine of different countries, possessing anti-inflammatory, antibacterial, antifungal, immunomodulatory, sedative effect. The melliferous plant is applied in decorative gardening. Two sam-ples received from the areas with different climatic conditions were tested: Dnepropetrovsk (Ukraine) and Turku (Finland). The tested samples differed from each other in the duration of vegetative peri-od, in particular the period from shoots before blos-soming. Among them Dnepropetrovsk sample an-nually passes a full cycle of development of shoots in new conditions, forms well ripened seeds with high sowing qualities. The samples propagated by self-seeding, which shows high capacity for intro-duction into a new environment. In the sample from Finland the period duration from shoots up to blos-soming is 10-15 days more. As a result the seeds of this sample ripe not every year. The habit of plants of Dnepropetrovsk sample also differs: its height of shoots and flowers is higher resulting in high decorative properties. The sampling for culti-vation of D. moldavica in Central Yakutia needs to be made taking into account the duration of vegeta-tive period. In our experiment in more thermophilic sample the dissatisfaction of its requirements to temperature conditions leads to the decrease in rates of development during critical periods, to lengthening of the period "sowing - blossoming". As a result the sample does not manage to pass all cycles of development, to create full-fledged seeds in the conditions of a short vegetative season and drops out of the experiment.
