Rattlesnake Master
Eryngium yuccifolium
Rattlesnake Master is a native tallgrass prairie perennial with stiff, sword-shaped, bristle-edged leaves resembling yucca and tall flowering stalks topped with small, spiky, globe-shaped flower heads in summer. It grows a deep taproot and does best in dry to medium, well-drained soil, tolerating drought and poor ground once established, though it resents transplanting after that point. The globular blooms are a strong draw for butterflies and other pollinating insects.
