It’s only a small pond – just a washing up bowl sunk into the corner of a raised bed.
The plant in the corner is Water Mint. Most of the rest is gravel or bricks, which form steps to get out if anything falls in.
I think I’ve told you all this, but as you can see from the main picture we had our first dragonfly, a Southern Hawker. Not sure if it’s a coincidence or if the “pond” really worked.
