The plane trees of France. Apart from Paris, one of my first memories of la France was as a teenager, driving down to the French Riviera. It took two or three days as we drove through tiny villages, stopping for long lazy lunches in the sun. There were no autoroutes in those days.
Narrow country roads, lined with plane trees - I've never forgotten - the beginning of my love affair with France.
Here's one of those wonders in the Jardin Biovès in Menton.
