About Rattlesnake Master

Rattlesnake Master is one of the most unique and architecturally striking plants of the American tallgrass prairie. Standing 3 to 5 feet tall, it features tough, blue-green, yucca-like leaves with small spines along the margins, giving it a distinctly desert-like appearance. In mid-to-late summer, it sends up sturdy stalks topped with spherical, bristly white flower heads that look like miniature planets. These flowers are an absolute magnet for an incredible diversity of pollinators, including rare wasps, bees, and butterflies, and it serves as a host plant for the Rattlesnake Master Borer Moth. Native to prairies and open savannas of the central and eastern United States, it thrives in full sun and is remarkably drought-tolerant once established due to its deep taproot. Because of this taproot, it is best to plant it in its permanent home rather than attempting to transplant it later. Rattlesnake Master is a conversation starter in any garden, offering unmatched structural interest and exceptional ecological value.
