53 taxa of perennial plants were planted in heavy degraded black earth in the fall of 1996. During the winter of 1996-97 the minimum air temperature of -20.9 deg C was recorded on December 29, 1996. During the winter of 1997-98 the minimum air temperature of -15 deg C was recorded on December 17, 1997. 25 taxa survived winters with no losses (100 percent survival). Among them ware plants, such as Artemisia stelleriana, Azorella trifurcata, Draba bruniifolia, Phlox subulata 'Maischnee', Sedum spectable 'Brillant', Thymus xcitriodorus 'Golden Fleece' and Veronica incana, which usually perform best on light, sandy and dry soils. These taxa can be considered as able to adapt to diverse soil conditions. Taxa which did not survive winters inncluded Doronicum plantagineum, Echinops ritro, Euphorbia polychroma and Papaver orintale
