When Colette is in Paris, invariably she goes to gardens and parks (while I hang out in museums). I've tried unsuccessfully to get her interested in blogging about them, but to no avail.
So I'm starting this category myself and will do my best to substitute for her.
I have no data, but if memory serves me her list of favorite places would look something like this:
The Park Monceau
The Buttes Chaumont
The Andre Citroen
The Georges Brassens
The Parc Floral at Vincennes
The Rosarie in the Boulogne
