Phenological development of perennial plants in the "Shadow garden" of Botanical Garden of the Petrozavodsk State University

Data on the phenological observation of 44 herbaceous plants taxa of the exposition «Shadow Garden» at the Botanical Garden of Petrozavodsk State University (South Karelia) for the period 2016-2018 are presented. The contrast of weather conditions during the studied vegetation periods allowed us to assess the limits of variation of the phenological phases and the fruiting characteristic, for a number of taxa - the relationship between the development of the generative sphere and temperature. The studied species are evaluated as promising and well-adapted for cultivation in the conditions of Southern Karelia.
