Morpho-biological features of the development of 5 species of the genus Hemerocallis in the conditions of the forest-steppe zone of Western Siberia are studied. The results of ontomorphogenesis are presented. 8 ontogenetic states are described. It is noted that the pregenerative period of ontogenesis lasts 2 years. The generative period of ontogenesis occurs at 3 years in plants developed from seeds. The species specificity in the formation of generative organs in autumn (H. minor, H. citrina, H. lilio-asphodelus) and the spring growth period (H. fulva) was establish. A palynomorphological analysis of pollen grains of 4 species (H. citrina, H. minor, H. middendorfii, H. fulva) was carried out. The implicitly polycentric type of biomorph is determined. Complete morphological disintegration is characteristic of underground organs. The possibility of ex situ conservation of species by seed and vegetative reproduction is noted.
