Do you recognize this tallgrass prairie plant?

Well, it is a member of the carrot family.


Early European settlers thought its roots could provide an antidote to rattlesnake bites.

They were wrong.


The plant somewhat resembles yucca (soapweed), except that it’s flower is very different.


It’s probably easier to identify from the flower…

In a crowded field of distinctive and unique prairie wildflowers, rattlesnake master holds its own. Its spiny leaves and characteristic round white flowers help it stand out, even in prairies, roadsides or flower gardens loaded with many other showy species.  Pollinators seem to appreciate its blooms, and many different insects gather nectar and pollen from them.  Rattlesnake master just barely occurs in Nebraska – reaching into the very southeast corner of the state – but is common in more eastern tallgrass prairies.

  1. We have a small patch at Homestead NM of America (near Beatrice, NE). It is located on the hillside where the CCC planted the prairie sod in the late 1930’s. The sod was harvested just a few miles from here. It would be interesting to know if it came with that sod or if it was from seed that was purchased and thrown out. Either way it is a very cool plant to encounter.

  2. One of my favorite plants! It’s not native here in Vermont, but does occur in the wild in extreme southwestern New England (Connnecticut). I learned it as a child in Illinois and loved its common name. In my garden, it’s very popular with mud dauber wasps, small native bees, and hover flies. It’s attractive in all seasons, from the rosette of strap-like leaves in the spring, to the heads of white flowers beginning in July, to the rigid stalks and bristly seed heads that stand above the snow all winter.
