Discuss Eryngium giganteum (Miss Willmott's ghost) with other Shoot members.
I have always wanted this plant and am thrilled with the one I purchased in a pot earlier this year. It is flowering well. But I was very disappointed to find it described in this month's Gardeners World magazine as a "biennial" which will die after flowering. Your database describes it as a perennial. Can you reassure me it should be there (and hopefully improved!) next year?
"Shoot's extensive plant A-Z is second to none. Highly recommended!"
