Finally, a solution for keeping houseplants hydrated that doesn't involve stuffing upside down plastic water bottles into the soil. These handblown glass vessels from Kikkerland are designed to allow a slow drip of water to potted houseplants over the course of several days. Head to the beach without worrying over parched plants.
Above: Each Water from a Stone vessel holds 7.5 ounces of water; $13 each from Kikkerland.
Above: Tucked into a potted plant, the glass plant waterers provide irrigation without overpowering the pot or plant. If you're as bad about remembering to water as I am, they're innocuous enough to leave around even when you're not away for the weekend. Lazy gardeners, unite.
