Ginkgo

I had the privilege of walking by a ginkgo tree as it was shedding it's leaves today. Apparently, they shed all their leaves in a very short time span (sometimes in 1 day).
We walk by the tree almost every day, but today was different. There were all of a sudden so many leaves on the ground that you couldn't even see the sidewalk. The leaves emit a very strange odor.
I've been walking at lunch around the same area for a few years now and this was the first time I was able to witness this event. We stopped for a while and looked up at the magnificent tree and watched the leaves streaming down around us. Just seemed kind of cool.

Ginkgo trees fascinate me.

Here are a few interesting facts:

The Ginkgo tree is the sole surviving species of the family Ginkgoaceae and is the world’s oldest living tree. In fact it is so old that the Ginkgo tree links us to the plant world of over two hundred million years ago. For this reason it is often referred to as a ‘living fossil’ The Ginkgo is the sole living link between the lower and higher plants, between ferns and conifers.

During autumn, the leaves turn a bright yellow, then fall, sometimes within a short space of time (1–15 days)

Extreme examples of the Ginkgo's tenacity may be seen in Hiroshima, Japan, where four trees growing between 1–2 km from the 1945 atom bomb explosion were among the few living things in the area to survive the blast (photos & details). While almost all other plants (and animals) in the area were destroyed, the ginkgos, though charred, survived and were soon healthy again. The trees are alive to this day.

There are no native ginkgoes living in the wild. All wild trees were wiped out hundreds of thousands of years ago but human intervention has saved the modern tree.

Gingko biloba is most effective as a concentrated extract, found in either liquid or tablet form. It has beneficial effects on the circulatory system, particularly among the elderly. Studies have shown it can help in treatment of their short-term memory loss, headache, tinnitus (ringing in the ears) and depression by improving blood flow in the arteries and capillaries
