No pots, just plants floating in air

From afar, they look like hairy grapefruits floating in midair. Up close, they're your introduction to kokedama. It means "moss ball" in Japanese, and it involves embedding plants in mud balls, covering them in moss, and suspending them from the ceiling for display. Despite the heavy sound of it, it's a lighthearted amalgam of many things - bonsai, the Japanese art of growing small trees in dishes or pots; terrariums; hanging gardens; and other forms of living sculpture.
