Yes, the entire country participates on the same weekend. Planning an outing is made easy with booklets and a beautiful web-site for each of the regions. Add in a little patience as the gardens often seem to be in the middle of nowhere, but what a way to pass through new countryside. Every stop will prove to be worth the adventure for one reason or another.
This year Tom and I headed south to the Midi-Pyrenees region. Our goal was 4 gardens Saturday and 3 on the return Sunday. We ended up making 3 and 3 as each garden was so spectacular in it's own individual way and time just ran out.
I apologize that these photos do not give justice to any of the gardens. There was no way to capture the spirits of the gardens with my little instant camera and the glaring mid-day sun didn't do anything to help.
My suggestion would be to check out all that was offered this year and put the weekend on your calendar for next year. Most of the gardens are ones that are normally open to the public, but by finding your way to one or two private gardens this will turn into a magical experience not to be missed by avid gardener's- well anyone that loves a good ramble.
