Ginkgo Tree

__________________________________________________________________________





 My favorite tree, ginkgo, is a tree frequently unnoticed until it drops its leaves. What an unusual shape for a leaf and it is such a beautiful and brillant yellow shade in the autumn!  It's leaf is fan-shaped or "duck-feet" shaped. The fruit is produced only by the female tree.

Arborists prefer to plant male trees due to the cheesy scent of the fruit produced on the female tree.

Rarely, a ginkgo tree with fruit is found. I was happy to capture these photographs of a female tree with ripe fruit at the Arboretum. The Arboretum is a great place to see a broad spectrum and diversity of trees.

Two traits appreciated by ginkgo lovers are the golden fall color and in just 1-2 days the leaves fall to the ground making cleanup quick and easy.

If you would like to see something very old and something very beautiful, watch an ancient tree growing next to the Gu Guanyin Buddhist Temple in the Zhongnan Mountains, China. 1,400 year old ginkgo drops it's leaves (link no longer available).
