Summary
How to Grow Blue Mistflower
Mistflower (Conoclinium coelestinum) is a fast-spreading perennial which creates a soft drift of fuzzy, blue-purple flower heads in fall. This plant grows best in average to moist, well-drained soils and can spread rapidly to form large masses. Plants can grow 2-3’ tall. It grows best in full sun to part shade. The blossoms of mistflower brighten the garden from September through October producing a lovely contrast in the late season garden. There are many companions that bloom at the same time and require similar conditions including great blue lobelia (Lobelia siphilitica), Fireworks wrinkle-leaf goldenrod (Solidago rugosa ‘Fireworks’), New England aster (Symphyotrichum novae-angliae), Bluebird smooth aster (Symphyotrichum laeve var. laeve ‘Bluebird’), black-eyed Susan (Rudbeckia fulgida), and New York ironweed (Vernonia noveboracensis). Formerly known as Eupatorium coelestinum. Zones 5-10.
