Eryngium-Yuccifolium 1C

Scattered along the stiff upright stem of this unusual perennial are tough blue-green yucca-like parallel-veined leaves. Smooth rigid stem bearing thistle-like flower heads made up of small greenish-white florets mingled with pointed bracts. The individual greenish-white flowers cluster into unique globular heads. These occur on branch ends atop the 6 ft. plant.
