Angelica hendersonii

Found on the coast of Western North America this has branching stems to 1.5m or more, topped by splendid rounded umbels of creamy white flowers in summer. Foliage is relatively thick textured, woolly underneath, and consequently the whole plant has the look and feel of a coastal species. Hardy and perennial. These are derived from stock originally from Oregon and tend to flower at 60cm high in my experience.
