I think that's one of our rain barrels.
It's a strange little space stuck between the patio and our grape vine. It used to collect junk until we cleaned it up and put in this little raised garden. The ground around the little morning glory garden is covered in mulch and flagstone since we have to get in there and move around quite a bit.
Here's the grape directly to the right of it. We got 7 large bowls of grapes from it this year and there are now six gallons of wine bubbling away from those grapes.
