Annotation The article presents the results of the introduction of 20 species and varieties of Hostain the forest-steppe zone of Western Siberia and describes the morphological features of the leaf and flower structure. The article studies the rhythm of the growth and development of the introduced species: Hosta albo-marginata, H. fortunei, H. decorate, H. lancifolia, H. plantaginea, H. sieboldiana, H. undulata, H. ventricosa, H. crispula, H. kikutu, H. rectifolia.The author describes the following varieties: France, Golden Tiara, White Beauty, Night before Christmas, Pacific Blue, Stiletto, Gould Tune. It is established that according to long-term data, the beginning of the Hostaregeneration in the forest-steppe zone of Western Siberia was observed on May 15–30, when the daily temperatures exceeded +15 оСand the soil warmed up to 10 о C. The duration of the vegetation period from regrowth to resistant frosts made up 98–112 days. The duration of flowering of one generative spring was 35–45 days. On average, the decorativeness of all types of Hostalasted from July to September until the onset of sustained autumn frosts. Six types of morphological structure of the leaf blade were identified: rounded-ovate, ovate-oblong, sagittate, cordate, lanceolate, linear-oblong. The flower color varied from white to purple, including different shades. There were from 10 to 55 pcs. in the inflorescence. All types of Hostaadapt well in the forest-steppe zone of Western Siberia, despite the fact that it is a heat-loving culture. The article describes the Hostacharacteristics. As a result of introductory testing, all types of Hostaare recommended for landscaping as plant indicators of urban and rodeside conditions.
