Moroccan Sea Holly problems — and how to fix them
Moroccan Sea Holly (Eryngium variifolium) is generally low-drama, 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 winter wet
The evergreen crown is vulnerable to sitting in waterlogged soil over winter; always plant in sharply drained soil and consider a protective gravel collar around the crown in wet climates.
Tap root disturbance failure
Transplanting or dividing established plants severs the taproot and plants frequently fail to recover; disturb as little as possible and propagate by root cuttings rather than division.
