Rattlesnake master (Eryngium yuccifolium) has a long history of use in prairie restorations, meadow plantings, rain gardens and naturalistic combinations. As a taller, summer blooming perennial with very striking form and flowers, it is finding its way in to water-wise landscape mixes and deer resistant plantings. This is an excellent component as an accent in a wildlife garden with its valuable nectar. The spiky, blue-toned leaves are also an ornamental feature and provide both contrast of form and texture with surrounding plantings. I’m a huge fan of the spherical, hovering flowers of this amazing perennial in the garden!
