It was held the vegetative reproduction of species subfamily Sedoideae Berger (Crassulaceae DC.) in the spring period. Top, middle, basal parts of shoots of first order and lateral shoots in full (40-50 pcs. of each sample) were used as cuttings. Optimal length of cuttings for most types is from 1.5 cm up to 2.5 cm, which consisted of 2-15 metameres depending on length of interstices. For successful reproduction of Sedoideae in spring the cuttings should be pre-rooted within 1-2 weeks before planting them in open ground. It is revealed that the roots of the cuttings of the top shoots and lateral shoots formed faster. It was noted the high percent of survival rate (up to 100%) of apical grafts and cuttings of lateral shoots, except for type of Ph. spurius var. variegatum (52,3 %). It is established that the survival rate of the cuttings of the medium and basal parts of shoots varied in different species and it was lower in comparing on with apical cuttings (50 %).
