Eryngium yuccifolium
Eryngium yuccifolium

A distinctive, native tallgrass prairie plant with attractive yucca-like foliage that is upright and toothed; tall stalks of showy greenish-white flower heads in summer that fade to brown in fall; tolerates hot dry sites; great in mass plantings

Ornamental Features

Rattlesnake Master features showy clusters of white ball-shaped flowers with light green overtones at the ends of the stems from early to late summer that fade to brown over time. The flowers are excellent for cutting. Its attractive serrated sword-like leaves remain bluish-green in color throughout the season.

Planting & Growing

Rattlesnake Master will grow to be about 24 inches tall at maturity extending to 4 feet tall with the flowers, with a spread of 3 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
