Eryngium yuccifolium
Rattlesnake Master is a native species to the tall grass prairies. Leaves of rattlesnake
master are parallel-veined, bristly-edged, sword-shaped, medium green leaves (to 3'
long) resembling those of yucca. Flowers are greenish-white and tightly packed into
globular, 1" diameter heads resembling thistles. The flowering heads attract many
kinds of insects
Rattlesnake master prefers dryish, sandy soils, but tolerates clay and shallow-rocky
soils. Plants tend to open up and flop in overly fertile soils or in anything less
than full sun. This is a taprooted plant which transplants poorly and is best left
undisturbed once established.
Use rattlesnake master in a xeriscape garden, perennial border, or native garden.
