The Ginkgo Tree is the only living exponent of an order of ancient seed plants, the Ginkgoales, which is standing between today conifers and deciduous trees. It comes from China, but today it is planted in parks worldwide. It can become over 1000 years old. There are female and male trees. Usually male trees are planted, because ripe fruits of the female trees have a smell like rancid butter, anyway they are used for food in Asia.
The two shrub-like Ginkgo, each with multiple stems, in the first 13 photos are growing on the edge of a plot of land slated for redevelopment, where an older high-rise building had been demolished. They have very large leaves, up to 18 cm wide, that are deeply divided (a variety? which I couldn't find in Roloff/Bärtels 'Flora der Gehölze' nor in the internet). Presumably they were already planted before the high-rise was demolished. There are no Ginkgo trees nearby.
