The Saint Petersburg Botanical Garden, also known as the Botanic Gardens of the Komarov Botanical Institute or the Komarov Botanical Garden, is the oldest botanical garden in Russia. It consists of outdoor and indoor collections situated on Aptekarsky Island in Saint Petersburg and belongs to the Komarov Botanical Institute of the Russian Academy of Sciences. It is 18.9 ha in area, and is bordered by Aptekarsky Prospekt (main entrance), Prof. Popov Street (second entrance), as well as the embankments of the Karpovka and Bolshaya Neva rivers.
The garden was founded by Peter I in 1714 as a herb garden in order to grow medicinal plants and re-established as a botanical institution under the name Imperial Botanical Garden in 1823. Ivan Lepyokhin was in charge of the botanical garden from 1774 until 1802. Beginning in 1855, Eduard August von Regel was associated with the garden, first as Scientific Director and then as Director General (1875-1892). Regel had a particular fascination with the genus Allium, overseeing collections of these plants in the Russian Far East and writing about them in two monographs.
More than 60 of the alliums he identified bear his name, e.g., A. giganteum Regel and A. rosenbahianum Regel. Many alliums can be viewed in the Northern Yard of the garden. In 1897, Konstantin George Alexander Winkler(14 June 1848 - 3 February 1900), became head botanist at the Garden. He then reorganized the herbaria and greenhouse collections. Around 1900, Boris Fedtschenko beacame head botanist and he organised investigations of various Russian regions including Siberia, Caucusus, Middle Asia and Asiatic Russia. All published in various volumes and books.
