Rattlesnake master gets its name from being utilized by Native Americans as an antidote for rattlesnake bites. This deep tap rooted perennial is native to the eastern half of the United States. It can grow to a height of 2-6 feet when growing in full sun, which it prefers. Tolerant of many different soil types it prefers dry to medium soil moisture levels in prairie and open woodland habitats, but will grow in wet soils as well. Blooming from June-September, the white spherical heads are made up of many tiny flowers with bracts that give the flower a prickly appearance.
