Rattlesnake master

Rattlesnake master, named for the erroneous belief that it could cure a rattlesnake bite, is a native prairie plant with medium grayish-green leaves and white globular flower heads that bloom throughout the summer. This perennial grows best in full-sun habitats with dry to medium soil and works well for more naturalize planting areas or massed in sunny borders. This flowering plant produces an abundance of pollen and nectar used by insects, including butterflies and bees. This species also supports the endangered rattlesnake master borer, a moth whose larvae bore into the plant’s stem and roots in order to pupate.
