Eryngium yuccifolium - Rattlesnake Master
Rattlesnake Master is a warm season perennial native wildflower that grows well on wet or dry to 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. Eryngium is Greek for "prickly plant" and yuccifolium is Greek for "yucca leaves".
