Rattlesnake Master problems — and how to fix them
Rattlesnake Master (Eryngium yuccifolium) 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
The leading cause of failure is heavy or poorly drained ground, especially winter wet; plant in sharply drained, lean soil.
Flopping when overfed or shaded
Rich soil and low light topple the stems; grow lean in full sun for self-supporting plants.
Resents transplanting
The deep taproot dislikes disturbance; site it permanently and propagate from seed rather than moving established clumps.
Sharp leaf margins
The rigid, finely toothed leaves can scratch; wear gloves and site away from paths and play areas.
