The stony ground around the tombs in Père Lachaise cemetery is free draining and dries out quickly.  Cracks and crevices provide limited root space and favour plants that can flower and seed quickly.   In the dappled shade of the main avenues ivy leaved toadflax (or ruin of Rome) decorates the monuments and herb Robert (Geranium robertianum) fills abandoned urns.

On this sunny slope red valerian (Centranthus ruber) is seeding freely and spreading a bright carpet of colour among the graves.   When I visited this morning a hummingbird hawk moth (Macroglossum stellatarum) was working busily from flower to flower, sipping nectar through its long, curved proboscis while hovering in mid air.   A memorable sight, but beyond the capacity of my photography!
