We were given Eryngium pandanifolium by the San Antonio Botanic Garden many years ago and have tested it to make sure it is winter hardy. It remained evergreen for four of those years and then died back at 10° F only to emerge from the roots in spring. This commanding plant grows on the pampas of Argentina. The bloom spike gets 6-8 ft. here forming a candelabrum of small reddish umbels. The basal clump has 3-foot sword-shaped leaves with spiny margins.
Late summer. 6-8 ft. x 6 ft.
Red Brown flowers
