Blue Mistflower

About this plant

Blue Mistflower, also known as Conoclinium coelestinum, is a cheerful and resilient perennial that brings a refreshing splash of true blue to the garden when many other plants are fading. Its fluffy, ageratum-like flowers emerge in dense clusters, offering a stunning visual display and a vital nectar source for pollinators during the waning days of summer and well into autumn. This vigorous, yet non-invasive, plant forms attractive mounds of dark green foliage that provide a lush backdrop for its captivating blooms. Its airy texture makes it an excellent choice for weaving through beds, naturalizing open areas, or adding a soft, ethereal quality to informal borders. Whether you're looking to extend the season of color in your garden or create a haven for butterflies, Blue Mistflower is an exceptional choice. Its easy-going nature and stunning floral display make it a must-have for both novice and experienced gardeners alike.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Blue Mistflower is a low-maintenance perennial. Cut back spent foliage in late winter or early spring before new growth appears. Can be divided every 2-3 years in spring to maintain vigor. Pinching back in early summer can encourage a bushier habit.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
