Eryngium yuccifolium - Rattlesnake Master

  • This is a unique plant best known for its bristly, round flower heads. It is named for its silvery blue-green spiky basal foliage which strongly resembles the yucca plant. This plant will stand out in any garden, individually or in groups. Attractive to a variety of pollinators, the highly textured flowers and leaves are unpalatable to both deer and rabbits. 

    It is a member of the carrot/parsley (Apiaceae) family, but is very different-looking from the usual umbel flowers and fine-cut foliage of plants in this family.  It is one of the host plants of the Black Swallowtail. 

    This plant is native to the eastern United States and considered a "near-native" to Ontario.
