Celebrating an anniversary in France led us to a small town in the Bourdeaux region where I found this planter. I've wanted to use it all this summer and voila here it is 3 days before the equinox and I finally figured out how to use it. I put a sedum in it then lit it up. Do you see the glow? I ran out every two to three minutes as the light took itself away. The three triple AAA batteries (are they called that in France) played the green in the night.
