This larger version of our bestselling willy the terracotta worm is on a mission to ensure that plants and flowers the world over remain well-watered.

As willy and the soil start to dry out he changes to a lighter color, letting gardeners and houseplant enthusiasts know that it's time to fetch the watering can. 16cm terracotta water sensor.
