This article presents the results of the study of two growing seasons (2022–2023) of Origanum vulgare L. (common origanum), O. vulgare ssp. virens (Hoffmanns & Link) letsw., O. vulgare “Severnoe Siyanie”, O. vulgare f. aureum. The characteristics of the onset of phenological phases, biomorphological indicators, the yield of green mass of a plant during the flowering phase were studied, the success in the conditions of cultivation in the northern forest steppe of the Bashkir Urals (Ufa) was evaluated. Studies on the biological characteristics of the above mentioned taxa of oreganum were carried out in the South Urals Botanical Garden-Institute of UFRC RAS at the collection site “Aromatic Garden”. Oreganums are perennial, rhizomatous, long-lived, summergreen plants with winter dormancy. According to the flowering period, they belong to the group of average summer plants with a flowering period of one month (a group of long-flowering plants). It was found that under the conditions of cultivation in the Bashkir Urals, the studied oreganum plants undergo a full cycle of life development, including flowering and seed formation (except for O. vulgare f. aureum). All studied forms of common oreganum grow well, develop well, form a well-developed above-ground mass. When evaluating the success of the introduction, the oreganum plants proved to be very resistant to the local climate, which makes it possible to recommend them for widespread use in the creation of herb gardens in the Bashkir Urals.
