The work presents results of introduction study on the Allium flavum in the conditions of culture in the Ufa Botanical garden institute. Bio-morphological parameters, seasonal rhythm of development, ontogenesis, features of reproduction and stability of species in culture are studied. According to phenotype and rhythm type it is a species with a long vegetative period, green in summer and rest in winter. Real seed productivity on one generative shoot makes up 195 pieces of seeds, potential seed productivity accounts for 516 pieces, umbrella reproduction coefficient makes up 38.4%. Allium flavum spread by seeds and by vegetative way. Allium flavum is very perspective species in culture.

Key words: Allium flavum, biology, introduction, germination, biomorphology, ontogenesis, seasonal rhythm of development, phenology, vegetation, seed productivity.
