Carol examines the intricate biology of the iris and looks into its intimate relationship with bees, using an endoscopic camera to reveal how the insect uses ultraviolet vision to see each flower. She also explores its cultural significance to mankind over thousands of years, learning of the importance of some species in the funeral traditions of Islam and its use in perfume manufacture in Florence. Plus, Carol meets an enthusiast rebuilding the iris collection of artist Cedric Morris
