The article discusses contemporary bio-ecological conditions of Taxus baccata L. in its natural distribution area of Georgia, particularly in Batsara National Preserve. Contemporary bio-ecological conditions of Taxus baccata L. spread in decorative gardening of eastern Georgia have also been studied based on the samples of the collection (47 pieces) of Tsinandali Arboretum. We have studied the periods of bud opening, vegetation ending, starting and finishing of cambium action, sprout woodening process, time and rate of growing in height, and regularities of accumulation-transformation of storage carbohydrates. The studies revealed that the Yew growth duration is affected by the snowless winter and frequent droughts increased in the last decades as they cause the lack of water in soils and badly affect the plant growth. Regularities of accumulation-transformation of storage carbohydrates and the studies of sprout woodening and cambium action peculiarities prove the strong ability of frost-resistance. In order to conserve this endangered species (Taxus baccata L.) it’s needful to introduce it widely in decorative gardening.
