The Ginkgo tree, indigenous to central China, can reach a height of 40 meters, and live as long as 100 years. It is a highly adaptable plant and can grow in almost any temperate or Mediterranean climate. It prefers rich, sandy soil, and has one or several main trunks and spreading branches. The leaves are petiolate, glabrous and bilobed. The Japanese call this species "I-cho" meaning "tree with leaves like a duck's foot". Each lobe is triangular with fine, fan-like radiate veins. The leaves turn yellow in autumn. The female trees produce a fleshy fruit with an edible kernel if there is a male tree nearby. These have long been a source of food in Asia. As Ginkgo Biloba is resistant to pollution and pests, the male ginkgos are very popular in cities.
