Abstract
The article is devoted to the study of the growth and development of medicinal annual Cota altissima (L.) J. Gay and two-year-old Arctium tomentosum Mill., Silybum marianum (L.) Gaertn. belonging to the Asteraceae family in the soil and climatic conditions of the city of Bukhara. The germination of seeds in laboratory and field conditions was determined. Due to unfavorable weather conditions and late spring, the seeds were sown in May. The growth and development of plants was observed one month later. Despite these species, they continue to grow. Cota altissima formed buds and flowers, and Arctium tomentosum and Silybum marianum remained in the virginal age state. All species adapt to the unfavorable conditions of the city of Bukhara.

Summary
The Republic of Uzbekistan is rich in species diversity of wild flora plants (4380 species). To meet the needs of the republic for medicines, an important task is the rational use of wild medicinal plants and the introduction of promising species to ensure the raw material base of pharmaceutical production. Rakhimova glycosides and other substances with valuable pharmacological properties [2] In this regard, there is a need to study the peculiarities of growth and development in the conditions of culture in different soil and climatic conditions of the republic. There is a need to study the peculiarities of growth and development in the conditions of culture in different soil and climatic conditions of the republic These species are being studied in unfavorable soil and climatic conditions of the city of Bukhara. Scientific research on the study of ontogenesis in various environmental conditions has not been conducted until recently
