Rattlesnake Master (Eryngium yuccifolium)

Rattlesnake Master (Eryngium yuccifolium)

Rattlesnake Master is the prairie's most otherworldly plant — its yucca-like spiky leaves rising in a bold rosette, its spherical white flower heads hovering on branching stems like something from a science fiction landscape. It is a plant that makes people stop and ask "what IS that?" — and the answer is one of the most ecologically significant and culturally storied plants of the North American prairie.

Prairie Movement & Ecological Role

Rattlesnake Master's spherical flower heads are among the most important pollinator resources in the prairie, attracting an extraordinary diversity of native bees, wasps, beetles, and flies — over 100 insect species have been documented visiting its blooms. It is a host plant for the Rattlesnake Master Borer Moth (Papaipema eryngii), a specialist moth found only where Rattlesnake Master grows. Its name derives from its traditional use by Indigenous peoples as a snakebite remedy — its roots were chewed and applied to bites, and it was carried as a protective talisman. The Meskwaki, Omaha, and other nations used it medicinally for a range of conditions.
