This is the first one I saw last summer. It’s a beauty to look at.
You can buy it now in the U.S. at Amazon for $140.
It was (and is) being sold by the UK garden retailers, like Primrose.
It’s made of wood, assembles in minutes, and holds up to 4 plants. Is it as good as the picture? The one U.S. Amazon review is negative, but the 6 reviews on Primrose are more positive.
The reviews note this “potato barrel” doesn’t have a bottom. Instead, it’s a grow bag with wooden slats (connected by wire) that wrap around to form the barrel shape.
