Blue Mistflower: Conoclinium coelestinum
Blue Mistflower
Conoclinium coelestinum
A beautiful native perennial with fluffy clusters of lavender-blue flowers that bring a soft haze of color to late-summer and fall gardens. Blue Mistflower is an excellent choice for rain gardens, moist meadows, pollinator gardens, and partly shaded areas where you want to support native wildlife.
Its delicate, fuzzy flower clusters create a striking display when planted in groups, attracting butterflies, bees, and other pollinators when many other plants are beginning to finish flowering. Its spreading growth habit can help fill garden spaces, making Blue Mistflower a wonderful addition to native plantings designed to provide late-season color and valuable resources for pollinators.
Growing Conditions:
Sun: Full sun to part shade
Soil moisture: Medium to wet
Soil: Moist, fertile soil; tolerates periodically saturated conditions
Height: 1–3 ft
Bloom time: Late summer to fall
Flower color: Lavender-blue to pale purple
Native range: Eastern and central North America
Wildlife Value:
Provides nectar for butterflies, bees, and other pollinators
Offers valuable late-season flowers when other nectar sources may be declining
Attracts a diversity of flower-visiting insects
Adds floral diversity to moist native gardens and meadow plantings
Don't Worry If It Doesn't Flower Right Away:
Native perennials don't always flower their first year, and that's completely normal! Young plants often put much of their energy into developing a strong root system and establishing themselves in their new environment. Depending on the species, you may see limited or no flowering during the first growing season, with more substantial flowering beginning in year two and beyond.
Watering for Establishment:
For the best results, water your new plants regularly during their first 6 weeks after planting, particularly during periods of hot or dry weather. Blue Mistflower grows best in consistently moist soil and can tolerate periodically wet conditions. Once established, it may spread through underground stems and self-seeding, particularly in favorable growing conditions.
Plant for the future: The first year is about putting down roots. Give your native plants time to establish, and you'll be rewarded with stronger, more resilient plants in the seasons ahead.
Garden Use:
Great for rain gardens, moist meadow plantings, pollinator gardens, pond edges, and partly shaded native perennial beds. Its soft blue-purple flowers pair beautifully with goldenrod, asters, and other late-season bloomers. Plant in groups to create a more noticeable display of color and provide pollinators with a concentrated source of nectar.
WNS Note:
Conoclinium coelestinum is a valuable native perennial for extending the flowering season into late summer and fall. Its spreading growth habit makes it useful for filling moist garden spaces, though it can expand readily in favorable conditions. Give it room to spread or plant it where its growth can be managed alongside other native species.
Sourcing:
Seeds were sourced from a wild population in Erie County, New York, supporting the use of locally sourced native plant material from the region.
