Striking rattlesnake master at home on prairie, in backyard
If you are fortunate enough to come upon an unusual plant that looks like a cross between a yucca and a thistle, odds are that you have found a prairie native called the rattlesnake master (Eryngium yuccifolium).
This striking, deeprooted plant belongs to the carrot family, as evidenced by the scent of crushed leaves. Tall, 2- to 5-foot stems arise from a base of powdery green, yuccalike leaves with spiky edges. The stiff plant branches out mid-to-late summer, bearing conical greenish-white flowers whose sweet honey fragrance draws a large variety of pollinators.
Rattlesnake master is low-maintenance, like most prairie natives. It has few or no pest problems, deer leave it alone, and its taproot allows excellent drought tolerance. Though it thrives in a variety of soil types, it is best grown in welldrained conditions.
Transplanting is difficult for taprooted plants, so gardeners should plan ahead when considering where the plant can be established with little disturbance. These tall plants might flop, especially in highly fertile soil or too much shade; provide support
by planting several together, or among grasses and other tall plants in full sun.
Remove flowerheads in the fall to control its spread or leave them on for winter interest. Fresh or dry, they also make excellent cut flowers.
Uses
The plant’s name might come from its alleged use as an antidote to rattlesnake venom, the efficacy of which is debatable. Native Americans and early settlers used dried roots of the rattlesnake master to treat venereal diseases and digestive disorders.
Archaeological evidence from cave sites in Missouri, Kentucky and Arkansas show that its fibrous leaves were used by prehistoric tribes to make rope, string, bags, shoes and clothes.
Today, its most important use is in restored prairie habitats, roadside plantings, rain gardens and as an ornamental in home gardens. It is a pollinator magnet that attracts bumblebees, sweat bees, honey bees, beetles, moths, butterflies, skippers and many fly and wasp species. It also is a host plant for some moths.
Plant it as an accent plant or en masse. Either way, this exoticlooking plant will add a delightful dimension to your garden.
