Ginkgo trees are said to have been introduced to Kentucky by Henry clay. Mr. Clay was given som ginkgo trees by the Japanese. Known to have been in existence since the Age of Reptiles, the ginkgo species is one of our oldest. Considered sacred among Buddhist priests, the seeds are eaten or pressed for oil in the Orient. Here we avoid them because they smell like rancid butter and when touched the smell lingers on the hands. The seeds can cause water blisters on some people. Although they are widely planted in the Bluegrass, male trees should be selected to avoid the smelly fruit produced by the female. The problem is determining the sex of the ginkgo, because it does not produce fruit until it is well over twenty years old. We must feel that they are worth the trouble, because whole Lexington streets are lined with beautiful fan-shaped yellow leaves in the fall.
