In Saint-Petersburg the earliest cultivation of trees and shrubs is connected
with Peter the Great and goes back to the first years of existence of the new capital of Russia. It is also connected with his personal physician Robert Erskine, a nobleman from Scotland, who signed the edict on establishing
the Apothecary Garden on 14 February 1714 (now the Botanic Garden of the Komarov Botanical Institute of the Russian Academy of Sciences, BIN). Using
the main literature sources beginning with the first Catalogue of J. Siegesbeck (1736), it seems to be that more than 5,000 woody taxa have been tested here during three centuries. Another important dendrological collection in the city
is the Arboretum of the State Forest-Technical University, FTU (established
in 1833). More than 2,000 taxa are present in St-Petersburg’s parks and 63 gardens today.
