Thirteen trees, each different but each recognisably the same.  The branches of each tree sweep upwards and outwards, then droop towards the tip in a spray of butter yellow leaves.

These trees, in Square Saint-Bernard-Saïd-Bouziri, are all specimens of Tillia cordata, a species of lime or linden tree from the Black Sea region.  Planted in 1964, the trees have been allowed to grow in their natural form, without pollarding or pruning, lending a gentle elegance to this small, neighbourhood park.
