Dahlias love the sun. In fact they need at least six hours of sunlight a day, so what better excuse is there for you to relax in the garden with endless tea in your Dahlia 1/2 Pint Mug? Dishwasher safe. Lower temperature wash and liquid detergent recommended to maintain appearance. Not recommended for use in the microwave. Earthenware pottery can sometimes get hot in the microwave so it's recommended that you do not put Emma Bridgewater pottery in the microwave. Not oven safe.
