Rattlesnake Master - Eryngium
The Rattlesnake Master plant was used by American Indians and pioneers who thought the roots could be used as an effective antidote for a rattlesnake bite. However, there is no true medical benefit for snake bites.
Eryngium Yuccifolium seeds benefit from a pre-treatment with 3 - 4 weeks of cold-moist stratification when planted in the spring. If planting Rattlesnake Master seeds in the fall, the winter cold is sufficient. Directly sow the Eryngium seeds in a weed-free seedbed and rake the flower seeds under 1/4 inch of soil.
Rattlesnake Master plants add a unique display to flower beds with their unusual compact flower clusters and flower seed heads, and they can be a wonderful focal point. Eryngium Rattlesnake Master can be used for roadside plantings, prairie restoration, prairie landscaping, wildlife cover, and also in wildflower gardens. There are approximately 7,500 seeds per ounce.
