Introduction In determining the monocarpic phenomenon, the authors, as a rule, tend to pass over in silence the mention of what part of the plant is monocarpic . As an example, most frequent are cited the annuals and perennial plants that bloom once during the period of his life and die. Sometimes the authors stipulate that monocarpic may be such perennials as “ agave , palm trees and other “ [1] . Material and methods The long-term observations of succulents from the collection of the Botanical Garden showed that this thesis  is not quite right and it is not limited only with  the annual and biennial plants and agaves . But even if we are talking about monocarpic phenomenon of representatives of the genus AgaveL., it is necessary to distinguish monocarpic plants and plants with monocarpic shoots. The main object of this work is an analysis of the monocarpic succulent plants and a defi nition of the term “ monocarpic plant “. Results and discussions The term “ monocarpic plant “ supposes the death of the whole plant after  ending  the generative period and reproduction only by seeds . The term “ monocarpic shoot “ suggests that the generative period  of plant is spreading over a time due to the fact that the infl orescences or fl owers are formed on only one or a few shoots of plants that die after fl owering , but the plant itself continues to grow due to the younger shoots. Among the perennial succulents the monocarpic phenomenon is typical for representatives of the families : Agavaceae, Crassulaceae, Dracaenaceae . Most we observe monocarpic shoots instead of the monocarpic plants, both in the woody and herbaceous representatives. In general, the list of genera , which are characterized with monocarpic phenomenon, is, as follows . Agavaceae. Agave L. - perennial monocarpic plants and plants with monocarpic shoots. Furcerea Vent. – perennial plants with monocarpic shoots. Crassulaceae. Aeonium Webb.et Berth. - perennial monocarpic plants and plants with monocarpic shoots. Aichrison Webb.et Berth. - the majority of representatives are the biennial plants , but some species are perennials with monocarpic shoots. Kalanchoe Adans. - within the genus occur both  typical biennials ( monocarpics  and perennials with monocarpic shoots. Greenovia Webb. et Berth. - Monocarpic plants Crassula L. - most members of  representatives of the genus are polycarpous plants  and some species - monocarpic plants and plants with monocarpic shoots. Dracenaceae. SansevieriaThunbg. - All members of the genus are plants with monocarpic shoots. Thus, in three families with succulents are represent different survival strategies of perennials : perennial monocarpic plants and plants with monocarpic shoots. The second type is typical for most woody plants: low shrubs and dwarf trees and contributes to a more widespread of species. The combination of seed and vegetative reproduction is typical for both woody and herbaceous plants. Conclusions The observation of growth and development has shown that the monocarpic phenomenon of perennial succulents is present. There is necessity to distinguish monocarpic plants and plants with monocarpic shoots.
