The results of studying Hemerocallis minor during introduction in the forest-steppe conditions of the Novosibirsk region are presented. The features of seasonal development taking into account the temperature factor are considered. It was found that in the conditions of the forest-steppe zone of Western Siberia, the flowering of H. minor occurred at the sum of positive temperatures of 703.5-828.0 °C. Information about the organogenesis of monocarpic shoot is given. It is shown that the generative shoot is laid in the year preceding flowering. In the pre-winter period, its condition is characteristic of the sixth-seventh stages of organogenesis. The life form of H. minor in the conditions of introduction belongs to short-rooted perennials, with a monopodially increasing axial shoot system of the rosette type and erect elongated generative shoots. The adventitious root system is formed by two types of roots: feeding and storing. The morphological description of seeds, their germination and productivity is presented. It is noted that seeds after 25-day stratification at a temperature of 5-6 °C germinate faster than without stratification. It was found that the coefficient of seed productivity had a value of 47.7 %. Xeromesophytic features in the anatomical structure of the leaf blade are revealed. Ulicny apparatus tetrazine type. The number of stomata on the lower epidermis of the leaf is 1.5 times greater than on the upper one. A well - developed mechanical tissue, the conducting sclerenchyma and the xylem and phloem.
