Avenue Foch 140 meters wide. In addition to the four thousand trees that line that avenue, the garden was originally planted with 2,400 different species of trees and plants, making it, as Alphand wrote, "a kind of arboretum." Many of the original trees can still be found in the gardens, including a chestnut tree from India, 4.7 meters in circumference; from 1852, an elm tree from Siberia, 3.8 meters in circumference (1852); and a giant Catalpa tree 3.5 meters in circumference (1852). The gardens contain a monument to their creator, Jean-Charles Alphand, designed by architect Jules Formigé, with sculpture by Jules Dalou.
