9 Rattlesnake master
ERYNGIUM YUCCIFOLIUM, ZONES 4 TO 9
Ominously named, this plant is known for its 1-inch, orb-shaped clusters of many small flowers. Whitish bracts stick out sharply from the flowers, giving the head a rough, prickly look and feel. This warmseason perennial grows best in dry prairie soil.
Why we love it: The heads give off a honeylike odor when in bloom from June to September.
Host to: rattlesnake master borer moth
9 Viceroy butterfly
