Maidenhair tree, Ginkgo biloba
1762
One of the oldest trees at Kew is a male maidenhair tree which dates back
to 1762 - less than 40 years after the first specimens had
been introduced to Europe from China. It is one of the few
trees at Kew remaining from the first botanic garden started
by Princess Augusta, George III's mother, in 1759. Its hardiness
was unknown, so it was planted against the wall of the Great
Stove glasshouse for protection. This was subsequently demolished
in 1861, which left the ginkgo standing alone. It is a multistemmed
tree, probably due to the transplanting and moving early
in its life which may have accounted for it losing its growing
point. Past curators of the gardens recall the tree being
grown against the wall of the great stove where it 'was trained
like a fruit tree'. Other instances of Ginkgo trees being trained in this
way have been reported. Several Ginkgo were planted at Kew in 1773 under
the direction of Sir Joseph Banks.
In 2002 it rightly became one of the 50 “Great British Trees” in
a scheme run by the Tree Council to celebrate the Queen’s Golden Jubilee.
Maidenhair trees are the only surviving members
of the ancient group of plants which was widespread at the
same time as the dinosaurs, 180-200 million years ago. Together with the
conifers, cycads and Gnetum, they are classified as gymnosperms (plants with naked
seeds). They have only been saved from extinction through cultivation.
The male trees have pollen-producing catkins, whilst female trees bear
the rather smelly seeds. In China, these seeds are used in bird's nest soup,
as a digestion aid, and as a hangover cure. Leaf extracts are used to treat
circulatory problems, such as tinnitus and Reynaud's disease (also called
white-finger), and are included in some after-shave lotions.
