Yerevan Botanical Garden that almost every plant species native to Armenia was represented in an area of approximately 16 hectares. At the same time, large rose and lily gardens were also created. In addition, there were more regions represented: the Caucasus, North America, Europe, Siberia and East Asia. The majority of the species in the collection belong to the plant families Cupressaceae, Pinaceae, Fabaceae, Caprifoliaceae, Oleaceae and Rosaceae, and the genera Juniperus, Quercus, Syringa and Clematis are particularly well represented. Plants grown in the park which are typical of the Caucasus include Quercus castaneifolia, Hedera helix, Corylus colurna, Juniperus sabina, Parrotia persica, and
