Eryngium giganteum 'Silver Ghost' problems — and how to fix them
Eryngium giganteum 'Silver Ghost' (Eryngium giganteum 'Silver Ghost') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in wet soil
Winter wet and poor drainage rot the crown. Grow in sharply drained, dry ground and avoid waterlogging.
Floppy or weak stems
Caused by shade or rich, moist soil. Provide full sun and lean conditions for self-supporting stems.
Aggressive self-seeding
Sows itself prolifically and can become a nuisance. Remove faded heads before seed sets if you want to limit spread.
Short lifespan / monocarpic decline
Plants die after flowering and setting seed. Allow a few seed heads to mature so replacement seedlings continue the colony.
