The article describes some bioecological features of the hyssopus (Hyssopus officinalis L.) species introduced to the Karshi oasis of Uzbekistan. The growth and development of the plant, introduced for the first time to the conditions of the Karshi oasis, were studied. In the present study, information about the stages of ontogenesis of the hyssopus and their description is given, and the period and stages of ontogenesis are highlighted. The results of the study showed that the studied species goes through the stages of seedlings, juvenile, immature and virginal in the first year of ontogenesis. The juvenile stage lasted 14-16 days, and the virginal stage lasted 132-138 days. It was revealed that seed germination was 82% in laboratory conditions and 76% in field conditions, so it was recommended to sow seeds in open areas in March. It has been determined that in the first year of life, the plant develops branches up to the third order, and it enters the generative phase in the second year of life. In the conditions of the Karshi oasis, it was observed that the hyssopus plants did not enter the subsenile stage in the three experimental years and also in eight years from the original plant from which seeds used in this experiment derived.
