| The forebears of the Ginkgo family (Ginkgoaceae) were found all over
the world about 160 million years ago. Gradually, the family members declined and
only the Ginkgo tree that we know today survived, in a couple of
provinces in Eastern China.
Originally designated as a conifer, although it evolved separately from
these trees, it remains technically under this heading. It is now the oldest
living tree species. It has
withstood two ice ages and even atomic blasts can’t discourage it:
standing proud within a mile of the Hiroshima epicentre are several
large Ginkgo trees, and Alfred Vogel noticed some very fine specimens
near Nagasaki when visiting Japan.
Ginkgo trees take
a long, long time to mature, with one Chinese emperor waiting for most
of his lifetime for the fruit of his transplanted Ginkgo tree to grace
his meal table.
Vogel planted a Ginkgo tree in his garden in 1973 and
it is doing well. Kew Gardens received a specimen from Japan in the
1760s, and it is now noted as one of the best ancient trees in the UK.
‘Ginkgo’ means silver nut or apricot, and the word ‘biloba’ refers to
the bi-lobed leaf shape.
The trees are venerated in
Asia, often found planted near to Buddhist temples. The oldest known
specimen, over 1,000 years old, is found at a temple in South Korea.
Diseases
and insects attack these trees to no avail. Modern day atmospheric
pollutants seem unable to deter them from strong growth. They genuinely
appear able to weather all storms. This may be due to the amount of
antioxidants found in the plant itself, which in turn makes it of
benefit to those who supplement their diet with extracts from the tree.
