This beautiful garden is located close to the Central Stadium and the Arboretum. Its centerpiece, the Friendship Tree, is a unique experiment started by horticulturalist Fyodor Zorin in 1934. It is a wild lemon tree, onto which branches of other citrus trees, including orange, grapefruit, and tangerine trees, have been grafted. The tree has branches added by people from more than 160 countries, some of them famous politicians, scientists, astronauts, and cultural figures. The landmark celebrates internationalism and peace. The garden has a museum where various gifts to the Friendship Tree are collected.
