  • $ 5.25

Rattlesnake master (Eryngium yuccifolium) is a unique wildflower with leaves like a yucca, and unique golfball-like flowers. It makes an excellent focal point in the garden when planted individually, or in groups. Native Americans brewed a tea from the root as an antidote to rattlesnake venom when roots are chewed and put on the bite as a poultice. 

From PFAF -The plant is diaphoretic, diuretic, emetic (in large doses), expectorant and febrifuge. A decoction of the roots has been found useful in cases of exhaustion from sexual depletion, with loss of erectile power, seminal emissions and orchitis. A tincture of the roots is used in the treatment of female reproductive disorders. The pounded roots are used as a diuretic. An infusion of them is used to reduce fevers. Chewing the root increases the flow of saliva.


Other common names include Button Snakeroot, Yucca-leaf Eryngo, Corn Snakeroot, Rattlesnake Flag, and Rattlesnake Weed.

How to Grow:

Lightly cover in tray.  Keep moist.  Germination is uneven and occurs in 5-90 days at 70 degrees.  You may mix with damp sand and place in the refrigerator for 60 days prior to sowing to even out the germination rate.  Prick out seedlings and transplant into their own pot or cell.  Move to their desired location after reaching at least 6 inches and hardening them off.  Keep moist in the garden.
