An ancient tree (on Earth 150 million years), Ginko biloba is well known for its medicinal qualities. It is also a beautiful ornamental tree in its own right with an open upright growth habit with massive branches at maturity. The foliage is fan shaped and a pretty lime green in the summer and a stunning golden yellow in the fall. Few trees compare to this one for fall color. Select male clones, as the female fruity is malodorous.
Alternate, simple, 1 to 2 inches long (in clusters on spur shoots on second-year twigs). Fan-shaped with forking, parallel veins. Leathery texture. Fall color is an excellent yellow-gold. :Bright yellow in fall
Buds are mounded, with distinct form and leaf scars.
