Grey green makes complete sense in the context of a temple wall or a mossy stone path. In North America people sometimes ask if the plant is sick. The Grey Green Monch Aster is a ceramic wall flower, 5 inches across, one screw, no water. It holds the quality of something placed deliberately in a space that was thought about. The aster has been asked about fertilizer. It has no plans to change. The glaze has been there longer than the question and will be there after the question stops being asked.
