ORNAMENTAL PLANTS OF HORTICULTURE VALUE
Hardy trees and shrubs for special environmental conditions
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
"Hillierís 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.
Brief descriptions follow and include:
- Latin name of the species.
- English (if any) name of the genus.
- Family name.
- Short description of the plant and special peculiarities.
Z - most appropriate USDA hardiness zone
New - new to cultivation
The accompanying Recommended Literature provides further information for
ornamental species native to the FSU.
