Urban Gardening From busy metropolises like Paris, Tokyo and New York sprouts the idea of kitchen gardens cultivated in tiny backyards, on rooftops and even within private flats. Big cities’ residents want to enjoy the food they have grown themselves. This spring, Holmegaard meets all design-loving plant enthusiasts with the self-watering plant glass Gaia. Its innovative, user-centered design was created by US glassware designer Aric Snee. Gaia Plant glass gives you a helping hand to ensure your fresh herbs will get the exact amount of water they need.
