Ginkgo biloba, like dawn redwood (Metasequoia glyptostroboides) is one of only a handful of deciduous conifers.  Ginkgo leaves have an unusual pattern of parallel veination - one can almost imagine a time many thousands of years ago when perhaps ginkgoes had needles instead of leaves and over time and evolution those needles fused together to create this most unique leaf.  According to legend, once fall temperatures drop ginkgo loose all of their leaves within a 24 hour period.  Too bad too - fall color alone is good enough reason to plant ginkgo.  The fraternity Xi Sigma Pi holds an annual raffle predicting when the leaves will fall.  For details, check out their table on the second floor of James hall.

In terms of landscape use ginkgoes are pretty tough customers, withstanding polluted city conditions, a myriad of pests and exhibiting a reasonable tolerance to salt.  When selecting a gingko it is best to opt for a male tree as the female trees bear a rather messy, foul smelling fruit.  Most nurseries are careful to offer only males.

Ginkgo biloba has been used in Chinese medicine for many years to enhance memory, learning capacity and help the respiratory tract. During the past two decades, hundreds of studies have confirmed many of ginkgo's ancient traditional uses. Modern clinical use focuses on ginkgo biloba's positive effect on circulation and its effects as an antioxidant.  Recently, ginkgo extract has been included in clinical therapeutic treatments for memory deficits including Alzheimer's disease, poor concentration, depression, dizziness, tinnitus (ringing in the ears) and headaches.

The ginkgo pictured here is growing in the courtyard between Morrill and James halls.
