black  Poplar

Lombardy Poplar      old black poplar

              The black poplar is one of the native trees, i.e. it arrived in Britain, naturally, before the English channel formed. It has fewer branches than the London planes, but what branches there are, are more powerful. The leaves are triangular or pear shaped. In the case of the trees at Joseph Grimaldi park, they are large, but generally their size is proportional to the size of the tree.

              It used to be a much more common tree in Britain, hence it is featured in Constable's famous painting: the Hay Wain. It is rare in central London, because it likes to grow by water, but there are three large ones and a small at Joseph Grimaldi park.
