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.

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.
