Ivory Sea Holly problems — and how to fix them
Ivory Sea Holly (Eryngium eburneum) 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.
Root rot in sustained winter wet
Although more moisture-tolerant than other species, prolonged waterlogging in cold weather can still rot the crown; ensure surplus water can drain away freely in winter.
Wind damage to tall stems
The tall candelabra stems, sometimes reaching 180 cm, can snap or topple in exposed positions; stake in late spring or site against a sheltered wall.
