description Mistflower Overview
Mistflower, Conoclinium coelestinum, is a perennial wildflower native to eastern and central North America. Its compact flower heads contain many fine blue to violet tubular florets, creating a soft, fuzzy appearance similar to that of ornamental ageratum. It grows in moist meadows, woodland margins, stream banks, and disturbed ground, and its late-season flowers provide nectar for butterflies and other pollinating insects.
help Mistflower FAQ
Is mistflower the same plant as annual ageratum?
No, native mistflower is Conoclinium coelestinum, a perennial native to eastern and central North America. It resembles the bedding plant Ageratum houstonianum because both produce fuzzy clusters of blue-violet florets.
Does mistflower attract monarch butterflies?
Mistflower provides nectar for monarchs and other butterflies during its late-season bloom. It is not a monarch host plant, however, because monarch caterpillars feed on milkweeds in the genus Asclepias.
Will mistflower spread through a garden?
Yes, it can spread by rhizomes and self-seeding, particularly in moist soil. A single planting may develop into a broad colony if the surrounding ground remains consistently damp.
Where should mistflower be planted?
It grows well in sun or partial shade with moist soil, making rain gardens and stream margins suitable sites. Established plants commonly flower from late summer into autumn.
