This article includes the study of the biological cycle of red hot pokers under the climatic conditions of the Republic of Moldova. The following species served as research subjects: Kniphofia uvaria (L.) Hook., K. ensifolia Baker, K. tukii Baker, K. nelsonii Mast., K. sarmentosa (Andr.) Kunth. The research was conducted during 2008-2017, in the collection of non-traditional perennial plants of the “Alexandru Cibotaru” National Botanical Garden (Institute). The phenological study and correlation between the onset of phenological phases in the introduced plants and environmental factors (T °) was analysed according to the classic methods. The red hot pokers, introduced into a new environment, have kept their seasonal pace of development as in the area of origin (South Africa). However, the calendar dates for the onset of phenological phases and their duration have changed.
