Ginkgo biloba

Ginkgo biloba is a deciduous conifer, and one of the best known examples of a living fossil, having remained unchanged for millions of years. It's grown in gardens for its attractive shape and the curious fan-shaped leaves, which turn yellow in autumn. Female trees produce small plum-like fruits with rancid flesh, though the kernels are edible. The nut-like gametophytes found inside the seeds are a traditional Chinese food, believed to have health benefits.

For best results grow Ginkgo biloba in well-drained soil in full sun. It rarely suffers disease problems and is attacked by few insects, making it an excellent urban street tree.
