Spring Grove Ginkgo is a dwarf tree with an upright pyramidal shape. It will mature to a height of 6 feet and width of 4 feet in 15 years and has a dense compact form. The leaves of 'Spring Grove' are bright green in color and grow in a whorled arrangement around the branches. This is a male clone and will not produce the distinctive strong smelling fruit. 'Spring Grove' has the typical outstanding golden yellow Ginkgo fall color, and with its dwarf size makes a nice accent in a smaller garden space. Like all Ginkgoes it is one of the most pollution-tolerant trees and works well in the city. Ginkgo is sometimes called the maidenhair tree due to its beautiful fan shaped leaves that resemble a maidenhair fern frond. The Ginkgo is an ancient deciduous conifer and evidence has been found which shows this tree coexisted with the dinosaurs. This cultivar was discovered as a witch's broom mutation on a male Gingko in Spring Grove, Ohio.
