Native Pollinator Power for the Smallest Gardens
Baby Joe Pye Weed (Eutrochium dubium 'Baby Joe') shrinks the beloved native butterfly plant down to a tidy 2 to 2.5 feet, making its monarch-magnet flowers available to even the smallest garden or container. Dense, dome-shaped clusters of mauve-purple bloom from midsummer into fall above dark green foliage, swarming with bees and butterflies. Compact and well-behaved, it's perfect for tucking into sunny borders and rain gardens in Edina, Eagan, and Apple Valley.
