Rattlesnake Master (Eryngium yuccifolium)

from $8.00

Rattlesnake Master is one of the most architectural and otherworldly plants in the tallgrass prairie. With its stiff, sword-like leaves and bristly, globe-shaped flower heads, it looks more like a desert yucca than a member of the carrot family. It adds a unique "silver-blue" cool tone to the garden.
