Curiosities

The Ginkgo is a very primitive tree. Its origins are in the Mesozoic as fossils demonstrate. The survival of this species is due to the Buddhist monks who planted Ginkgos around their monasteries in the belief that they protect against fires, considering them sacred trees. Ginkgos are dioic trees which means that there are female and male trees. The female ones produce a false fruit because it’s an ovule which, if there is no male tree nearby, remains unfertilized. In street plantations the male ones are preferred because the ovules that fall to the ground ferment and produce a nauseating odour. The edible seed, uncooked or toasted, has a similar flavour as the chestnut.
