Ground-elder is also known as bishop's weed. Ajwain (also known as carom seeds or bishop's weed), is an uncommon spice except in certain areas of Asia. It is the small seed-like fruit of the Bishop's Weed plant, (Trachyspermum ammi syn. Carum copticum), egg-shaped and grayish in colour. The plant has a similarity to parsley. Because of their seed-like appearance, the fruit pods are sometimes called ajwain seeds or bishop's weed seeds.
