Rattlesnake's master is a common name for several plants in the Aster family, including Eryngium yuccifolium, which is also known as button snakeroot, and Eryngium aquaticum, which is called water eryngo or rattlesnake master. These plants are native to North America and are known for their spiky clusters of tiny flowers that resemble a prickly ball. Other synonyms for rattlesnake's master include corn snake root, Texas toothpick, and adder's tongue. These names are based on the plant's traditional use in Native American medicine to treat snakebites, fever, and other conditions. Rattlesnake's master is also popular among gardeners as an ornamental plant because of its unique appearance and tough, drought-resistant nature.
