Botanic gardens and arboreta and their collections of woody species possess an enormous scientific and educational value. The selected pictures below were taken in the Botanic Garden of the University of Fribourg (Switzerland), in the Botanic Garden of Lyon (France), in the Botanic Graden Berlin-Dahlem (Germany) and in the Arboretum of Kornik (Poland). Our iconographic collection grows constantly and contains more than 3,000 photographs of trees and shrubs from ex-situ cultures.
