Blue Mistflower
Conoclinium coelestinum
Blue Mistflower is a fast-spreading herbaceous perennial that forms loose colonies from creeping rhizomes and self-sown seed. Flat-topped clusters of fuzzy, sky-blue to violet flowers cover the plant from mid-summer into fall, drawing butterflies and other late-season pollinators in large numbers. It thrives in consistently moist, fertile ground in full sun to partial shade, tolerating occasional flooding, and spreads readily enough to need room or a barrier to stay in bounds.
