I may resist the assumption that french food is always better than British. Or that french cheese is necessarily superior to local cheeses over here. (if you can find somewhere to buy them, that is...)
But windowboxes and balconies - the french do better.
I first saw window boxes with cactus and these succulent-type houseleeks in Barcelona - tumbling, sometimes for 4 or 5 storeys, down the side of the building.
I love the way these complement the colour of the paintwork around the window, against the peachy colour walls.
This next one I like because the plants are so wantonly unkempt.
