Nursery contributed plant descriptions

An interesting combination of the prehistoric and the refined, this evergreen Eryngium is known for its large-coned, luminous flowers. Linear leaves emerge from a basal rosette with widely spaced spines along their margins. A dramatic collar of upturned, unequal steely green bracts, some reaching the striking breadth of 5 to 6 in. across, serves up central, sea-green flower heads reminiscent of a Protea. Ideal for dried arrangements, this exotic Mexican perennial demands a warm, sunny site with well drained, fertile soil. Give it a blue pot on the patio or another prominent location to bring its remarkable show in-to full view.

Another spectacular new Sea Holly with flowers that do indeed look like a metallic silvery Protea, hardiness is untested but I suspect it is on the tender side here, on the other hand I thought that of agavifolium and it wintered just fine. ZONE 4

Architectural botany. This Mexican Sea Holly brings the exotic right into your garden. From a basal rosette of spined leaves arise tall stems bearing silver-white flowers reminiscent of Proteas. These last for a couple of months and are great dried. Fertile well drained soil.

A rare, STUNNING Eryngium from Mexico that bears very large, silvery white, Protea-like blooms on erect, multi-branching stems, 3’ to 5’ tall. Lustrous, jagged-edged, silvery foliage, too. Thrives in poor, dry, well-drained soil & fab in a container. Incredible cut flower fresh or dried.
