When you walk out to your garden at night, everything looks a bit ominous. Shadows hang on everything, and if you’re tired, a bush can look like a wild cat waiting to pounce on you (this definitely isn’t speaking from experience). While you could always put out solar lamps, they’re usually just a tad too much light.
If you want something that will help you see without being too obtrusive, then the Glow In The Dark Pebbles might be of some use. This set of 100 pebbles will soak up the sun all day, and will provide two to three hours of glow once it’s dark out. This can illuminate a path, define specific flower beds, or be used as decoration in a fountain. They only cost about $10, and would give your garden a bit of a magical feel. Just make sure you don’t have any pets that might think these are treats for some reason.
