Eryngium giganteum
Miss Willmott's Ghost
Plant Type:
BIENNIALEryngium giganteum - Miss Willmott's Ghost flowers with large thistle-like flower heads in a silvery green to blue-green shade from branched stems upon the upper third of the inflorescence. Each flower has an inches tall pine cone-like structure rather like a giant thimble rising up from the center surrounded by spiny bracts at the base providing the fascinating foil for their bold and fascinating garden posture. These arrive in late spring and continue into summer from tufts of green serrated spade-shaped leaves at ground level. The flowering event lasts well into summer and is a magnet for all manner of flying insects: bee flies, bumble bees, honeybees and those wasps that prefer nectar to predatory forays. The Giant Sea Holly is a bold biennial that when happy will self-sow in part shade to full sun. A colony is memorable. Miss Willmott can haunt our landscape wherever she wishes. Once seen it is anticipated in all coming seasons. Might be best interred in spring for northern customers. Established plants from seed.
