Rattlesnake Master
Pale globes and swordlike leaves make this carrot-family plant look as if it belongs to a completely different botanical neighborhood.
Artwork inspired by Marvin Cone
Tiny flowers crowd into prickly-looking heads visited by a broad guild of wasps, bees, beetles, and flies. The common name reflects historical medicinal claims, not evidence that the plant safely treats snakebite.
Look in unplowed or well-restored prairie and verify the bracted flower heads plus parallel-veined basal leaves. Do not repeat the snakebite claim as medical advice, and never dig the deep root.
