Most people automatically think of a sundial, but you can also try a clock. Outdoor clocks are waterproof, and some even light up at night!
They add a touch of class to a patio or summerhouse, and create a focal point on a fence or wall. Alternatively, opt for a station clock to mount to the wall for a vintage feel.
Not only will they look great but it’ll help you to keep track of time when you’re out and about gardening. Some even have thermometers or humidity gauges too to make them even more handy.
