In my sister's yard grows, for our climate, an unusual tree ... GINKO. It was planted by her son more than fifteen years ago. I knew almost nothing about that tree ... but there's google and you find out everything. It is the oldest plant in the world, so Darwin called it a living fossil. Ginkgo originates from China, where there are trees as old as 4000 years, and it was brought to Europe in the eighteenth century. It is considered the most vital plant species in the world, and it amazes with its resistance to toxins from the environment. I only photographed a part, I didn't manage to photograph the whole tree ...
