The Q&A Archives: Sea Holly

Question: I had 3 very healthy sea hollys. After my husband watered the garden, one sea holly wilted;then the other one followed suit and both died. The remaining sea holly is doing well. Last year, the same thing happened. Any ideas why and how to prevent from happening again?

Answer: This (Eryngium maritimum) is generally considered a tough garden performer as long as it has full sun and very well drained soil. In my experience it also does best in a soil that is not terribly rich. It is possible that the drainage is less than perfect and they in fact "drowned", especially if you have a heavy soil. If the survivor happens to be in a slightly raised position or in a spot that receives less water, I would suspect drainage. A related plant, E. giganeum is actually a biennial and would die shortly after blooming, so that might be another possible explanation. I'm sorry about your plants!
