This is the largest flowering sea holly and definitely the most dramatic. Gun metal blue stems and equally blue thistle-like flowers with a conical flowerhead and intricate, feathery bracts. Graham Stuart Thomas rates this species “exceptional” in beauty and as a garden plant. No need to disagree! This peculiar genus from the carrot family is found around the world but with its centre of diversity in South America. There are also a number of European species.

Some sea hollies are native to rocky and coastal areas, but the majority are grassland plants.
