The Bishop Flower or Bishop Weed (Ammi Majus) is a hardy, upright annual with large domed, umbrella shaped, umbels that are densely packed with beautiful white flowers. With its bright and attractive foliage, this flower makes a fantastic foliage filler. Blooming over a reasonably long period, from early summer until fall, Ammi Majus remains a lovely cold season thanks to its dried flower heads. Bishop's flower is great for inexperienced gardeners and those that like low maintenance gardens.
