The aim of the study is to investigate the phenological characteristics, morphological traits, and evaluate the ornamental and biological qualities of the Hosta cultivars Golden Tiara, Francee, Night Before Christmas, Pacific Blue Edge, Stiletto, White Beauty, and Wide Brim, cultivated in the forest-steppe zone of the Novosibirsk Region. Flowering of the cultivars occurred when the sum of positive temperatures was 786–1224 °C. The growing season lasted 102–120 days. The studied cultivars had a summer-vegetating phenological rhythm type, an average level of cold hardiness (2–3 points), but had high viability in terms of frost resistance (5 points). In terms of plant height, they varied from miniature (20–22 cm) to giant (77–85 cm) sizes, and had an abundance of vegetative reproduction (10–13 ramets). Densely vertically rhizomatous and densely and loosely horizontally rhizomatous biomorphs were identified. A comprehensive methodology for assessing hosta biodiversity based on eight ornamental (100-point scale) and seven economic-biological (50-point scale) criteria was developed for the first time. The results of the evaluation of the ornamental qualities of Hosta varieties were 50–81 points, and the economic and biological qualities were 34–43 points. The introduction potential according to the comprehensive varietal evaluation under cultivation conditions was 90–126 points. The group of highly promising varieties included: Night Before Christmas (126 points), Wide Brim and White Beauty (113 points), Pacific Blue Edge (109 points), Francee (104 points), Stiletto (103 points); the promising variety Golden Tiara (90 points). The effectiveness of the practical use of Hosta varietal diversity as borders, flower beds, monogroups, mixborders, and solitaires in Siberian flower beds is based on the originality of the structure and color of the leaf surface, the productivity of vegetative propagation, and the assessment of the introduction potential according to a comprehensive criterion of decorative and economic-biological characteristics.
