3–6' tall. This North American native exhibits a rare and beautiful silhouette wherever it grows. 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.
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; a good resiliency plant for pollinators as our Northeast summers trend toward hotter and wetter.
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. Plant 18–24" apart in full sun in moist well-drained soil. Z3. (bare-root crowns)
