Hardy Trees And Shrubs For Special Environmental Condition
There are about 2,800 woody species in the flora of the FSU (Sokolov, 1965). Most of them are shrubs and semi-shrubs, only 20 % species are true trees. Ornamental trees and shrubs were described in many Russian publications and some are listed in recommended reading in this book. Species, which were mentioned in the Part 1 and unknown or poorly known in cultivation, are described below. Many of them are not present in the "Hortus, III" (marked as "New" in the list) nor in "Hillier's Manual of Trees & Shrubs (fifth edition)." All the species listed can be used in unusual areas where extreme environmental conditions prevail, such as very cold winters, very hot summers, or a small amount of precipitation, or in polluted areas. The brief information given for each species includes the Latin name of the species, the family name, a short description, the geographical distribution and habitat and the practical use. Most of these species are very attractive plants.
