Ginkgos were once
native throughout the Northern Hemisphere, but were rendered extinct in
North America and Europe during the Pleistocene Ice Age. They survived in
eastern China where they still grow today. The common name refers to the
leaf shape which is similar to that of the maidenhair fern. The ginkgo
is a drought-resistant, adaptable species, and is very cold hardy-thriving
from zone 3 to 9. It is very pH adaptable, tolerates air pollution and salt
pollution, making it ideal for adverse urban conditions. Male cultivars
are preferable: the odor of the fallen seeds unpleasant, and the abundant
crops can be very messy. |
