The research objects are the plants of 3 species and 1 variety of Deutzia in the Botanic Garden-Institute of VSUT (Yoshkar-Ola, Mari El Republic). Plants aged from 38 to 45 years grow in the exhibition “Fruticetum”. The study was conducted in 2015-2019. The height and diameter of plants crowns, their winter hardiness for the period from 1981 to 2019, the morphometric indicators of leaves and inflorescences, the possibility of vegetative propagation by herbaceous cuttings, and the size of annual plants were studied. According to the study results, the most hardy is Deutzia of Amur, which forms the highest shrubs. The long-leaved Deutzia has the longest leaf blades, Deutzia scabra ‘Plena’ has the smallest leaves. The long-leaved Deutzia has the largest inflorescences, Deutzia of Amur and Deutzia scabra ‘Plena’ have the smallest ones. Deutzia magnifica and Deutzia scabra ‘Plena’ have ornamentality advantage over other species due to the double flowers. For the maximum display of ornamental qualities, the plants need a successful overwintering. The greatest ability to reproduce by herbaceous cuttings is noted for Deutzia scabra ‘Plena’.
