‘Big Blue’ Sea Holly is an amazingly different color addition to the well-drained garden. It has silvery green thistle-like foliage which is topped by glowing blue stems and flowers. The blooms in June look like tiny blue artichokes, and are held well above the leaves. The more sun this plant recieves the more intensely colored the blue flowers will be. Eryngium ‘Big Blue’ withstands salty, coastal winds and sandy soil so a very good choice for seaside plantings.
