Rattlesnake Master Eryngium
Eryngium yuccifolium Also called Button Eryngo.
Shimmering globe-thistle-like 1" greenish-white flowerheads with feathered silvery-green bracts on smooth stiff stems surrounded by sharply cut leathery foliage. Emits a subtle honey-like scent during the heat of the day.
Exhibits a rare and beautiful silhouette wherever it grows. Fabulous for cutflower production—an excellent bouquet-builder, providing good structure for arrangements.
Attracts numerous types of long- and short-tongued bees, wasps, flies, butterflies, moths and beetles.
Plant 18–24" apart in full sun and well-drained sandy soils. Self-seeds freely over time. Plants tend to open up and sprawl if grown in rich soils or in anything less than full sun. Forms a taproot and is best left undisturbed once established. Native to prairies of eastern North America. MOFGA certified-organic. Grown at Ripley Farm. 3-6' tall. Z3. Maine Grown. (bare-root crowns)

Herbaceous Perennial Plants
When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. If they are slightly dry, add a little water or, if they are going to be potted up soon, wet the roots. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If you cannot pot them up immediately, store them in a cool (35–40°) location for a short time.
Do not plant bare-root perennial plant crowns directly outdoors.
Pot up the rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers.
Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°. Wet and/or cold conditions for an extended period may cause rotting.
Transplant outside once they show some top growth and the danger of frost has passed.
