(Maidenhair ) An extremely hardy tree, resistant to pollution and disease. Very attractive fan-shaped foliage. In the West, the male tree is preferred because the female produces a foul-smelling fruit. However, the fruit contains a delicious nut which is a delicacy in roasted or added to rice dishes. Medicinally, ginkgo is rapidly gaining a reputation as a brain tonic. According to recent European studies, the leaf extract increases blood supply to the brain and improves neural functioning and memory. Seeds take 3 to 12 months to germinate.
