ONE OF THE characteristics of a living organism is the ability to reproduce itself. Pollination of plants is an important stage in maintaining the survival of a species.

Yesterday (the 15th of May 2024), we saw a curious tree at Kew Gardens. It looked as if it had both green and white leaves. It is a Handkerchief tree (Davidia involucrata). The white appendages are not leaves but bracts. They form for about a fortnight each year, and serve to increase the chances of the tree’s flowers being pollinated.
