The trees in the foreground are dawn redwoods in Jubilee Park – an island of greenery amidst the skyscrapers of Canary Wharf. The dawn redwood is a fascinating tree. It was believed to be extinct and known only from ancient fossils, until a small stand was discovered in 1944 in the forests of Central China. (I allude, of course, to discovery by science; the tree was well-known to local villagers, without whose the help the botanists may never have discovered it.) The tree's morphology has not changed for 65 million years, which means that the trees in Jubilee Park are essentially identical to those in Cretaceous-period forests, when Tyrannosaurus roamed the earth.

The dawn redwood is also one of a very few conifers which shed their leaves in autumn. If it were evergreen, as most conifers are, the two photos above would have looked very similar.

The building in the background belongs to a law firm where I worked for four years.
