ERYNGIUM. Widespread, particularly in South America. A large group, mostly of perennials, with a variety of ornamental features. The leaves are often presented in attractive basal rosettes and are variously shaped and colored. The flowers are tiny and carried in conelike clusters, often with circles of showy bracts beneath. Many are tough and easily grown, given a variety of exposures, soils and watering regimes. The following should be hardy to 10^oF or less.

pandanifolium. This would be easily mistaken for a yucca or agave when not in bloom. It has crowns of narrow, pointed leaves 4-6’ long in older specimens, bluish green in color. The flower stems rise several feet above the foliage, widely branched in zigzag fashion and bearing many small, nearly bractless floral cones. They are spectacular in floral arrangements, and provide bold features in a large landscape.
