My love of botanical gardens started with the greatest of them all, Kew. This is a much smaller…read moregarden in Paris, which I give 5 stars to as it is really beautiful. Please read the excellent reviews in French. I am not surprised they note that many Paris folk do not know about it. After I visited, I told all my friends, many have lived in Paris 50+ years, and they never heard of it! The new greenhouses surrounding court Simonne-Mathieu of Roland Garros are the unique attraction. Though when I visited there had been significant vandalism, so 2 of the sides were closed. All the traditional buildings are in a terrible state. Let's hope the Mairie de Paris spends money on restoration, but go anyway. You can enter most of the hoses, and they are lovely. As noted by one French review, the cactus house is fabulous.
