What is the bluest eryngium
“Lots of eryngiums are strikingly blue,” say Brian and Kathy Pike. ‘The x group has some of the bluest. Look out for ‘Big Blue’ and ‘Forncett Ultra’.” The late great gardener Christopher Lloyd, who created the Great Dixter garden, considered x the best blue and said that the colour of eryngiums is bolder in full sun. Other gardeners report that dry conditions can also amplify the intensity of sea hollies’ blue colouring.
