Rattlesnake Master is a warm season perennial native forb which grows well on wet or dry mesic prairie soil. Plants grow 2 to 6 feet tall from a short, thick rootstock. The bluish green basal leaves are up to 2 feet long and 1 1/2 inches wide. The leaf bases clasp the single, erect stem. Flower heads are on stout peduncles at the tip of the stem. Each nearly spherical flower head is from 1/2 inch to 1 inch in diameter and is made up of small flowers.

Whitish bracts stick out sharply from the flowers, which give the flower head a rough, prickly feel and appearance. The heads have a honey like scent and are in bloom June to September. Individual fruits, which mature in the flower head, are less than 1/10th of an inch long.

The root of Rattlesnake Master has been used medicinally by American Indians and pioneers.
Eryngium is Greek for "prickly plant" and yuccifolium is Greek for "yucca leaves".
