Ginkgo -- Determining Sex
The only way to determine the sex of a ginkgo tree is to wait until the plants bloom. Male trees will produce an abundance of pollen in the spring.
Female flowers will have a single pistil in each flower.
Many trees produced at nurseries are grafted male trees. Buds are removed from male trees and grafted on to the rootstock of a seedling ginkgo, eventually becoming the top growth. Tree will usually be marked as "grafted male trees".
