Butterflies and native bees flock to its abundant nectar in late spring through early summer. Blue-green foliage on attractive silver stems forms a substantial vase-shaped clump. This North American native thrives in challenging conditions and tolerates poor soils. Once established, this plant becomes nearly carefree due to its drought tolerance.
