Abstract

The small dendrological garden in Glinna (about 5.5 ha) near Szczecin (northwest Poland) is well known for growing a lot of unique trees. The local mild microclimate in combination with the Atlantic climate of West Pomerania produce favorable conditions for growing many varieties of trees and shrubs which go freeze in the central and eastern Poland. The garden’s collection amounts to 750 taxons of trees and shrubs, representing 220 species. What is valuable in the collection of the arboretum is that the cultural varieties of the plants make only 14%. The special collection of the Garden are species of Chinese origin (200 taxons) and maples (65 taxons). Basing on the data from the literature, over 147 taxons used in conventional and unconventional medicine as well as in country medicine were distinguished, among which plants of Asian origin (mainly from China) predominate. This work presents the characteristics and the crop obtained from trees and shrubs rarely grown in Poland that possess medicinal properties, among others: Cunninghamia lanceolata, Torreya sp., Acer davidii subsp. grosseri, Asimina triloba, Broussonetia papyrifera, Clerodendrum trichotomum, Chaenomeles cathayensis var. wilsonii, Diospyros kaki, Eleutherococcus sp., Eucommia ulmoides, Lindera benzoin, Magnolia officinalis var. biloba, Phellodendron sachalinense, Poncirus trifoliata, Sassafras albidum, Symplocos paniculata, Zanthoxylum piperitum, Zanthoxylum simulans.
