Eupatorium coelestinum Seeds (Purple Mistflower)
Eupatorium coelestinum, commonly known as “Mistflower” or “Hardy Ageratum,” is a herbaceous perennial native to North America. It features fluffy, powder-blue to lavender flower clusters, resembling ageratum blooms, atop robust stems. Thriving in USDA hardiness zones 5-9, it prefers moist, well-drained soil and partial to full sun. Mature plants typically grow to heights of 1-3 feet, forming dense clumps. Eupatorium coelestinum seeds are available for propagation, making it a popular choice for pollinator gardens. It attracts butterflies and bees with its vibrant, late-summer to fall blossoms and adds a delightful pop of cool-toned color to the landscape.
