Eupatorium coelestinum 'Blue'

Eupatorium coelestinum 'Blue'


Common name: Blue Mist Flower, Wild Ageratum


For an impressive pollinator attractor, look to Blue Mist Flower. In late summer and fall, it's covered with ageratum-like blue flowers that pollinators adore. Note: It can make a pest of itself when conditions are right. Dead-heading helps contain re-seeding.


Our perennials come nestled in a 4" square CowPot with a free metal plant ID marker. Learn more about why we think CowPots are so awesome here.

  • How To Plant

    CowPots are made from composted cow manure. As the pot decomposes, it feeds the roots of the plant helping it get off to great start. We like to say the perennials think they're delicious and nutritious! :-)

    You will plant the pot along with the plant! No need to put holes in the pot or remove the bottom. It decomposes faster than all other non-plastic pot options and the roots easily push through.

    Place the plant in the hole so that the top of the soil in the pot matches the soil line in the garden. Ensure that soil is pressed against the pot on all sides and the bottom. Keep the area inside and outside the pot moist (but not soggy) for 3 to 4 weeks until the plant is established.
