This is the plant that produces those memory-enhancing extracts you see in the health food aisle of the drug store – the one that long-lived Chinese monks reputedly tended for thousands of years, brought from Japan to Europe by Dutch traders.

The picture came from the marvelous Old Book Illustrations site, which is an absolutely gorgeous resource. The encyclopedia engravings are just the beginning.
