Love-in-a-mist Nigella damascena 'Albion Green Pod' - pure white flowers with a prominent boss of stamens are framed by a collar of wispy foliage, creating a beautiful, ethereal effect. As the flowers fade, fantastic green seedpods develop, and both these and the flowers make wonderful additions to fresh or dried arrangements
Ammi Majus (Bishop's flower) has lacy, white flowers, like a more delicate form of cow parsley. Ammi Majus is the best white filler-foliage plant you can grow and spectacular arranged in a great cloud on its own. It forms larger, more prolific plants from an autumn sowing.
