Eutrochium purpureum

This is a very large perennial forb that would make an excellent addition to a shady pollinator or butterfly garden. Large, rich mauve-colored blooms top this clump-forming plant by mid to late summer and draw butterflies, moths, skippers, and long-tongued bees with its abundant nectar, in addition to some other solitary bees that collect pollen. A handful of caterpillars feed on the leaves and other parts of this plant, and many other insects (flies, leaf miners, aphids, etc.) also use this plant for food.

This is the largest of the common Eutrochium spp., growing up to 7 feet on sturdy stems that may droop under the weight of the large flower heads. This also prefers more shade than the other species and has fewer whorled leaves (only 3 to 4) per node. Staking may be required if not grown among other tall, robust plants like Cutleaf Coneflower or Tall Thistle. If you have room for it, this plant is stunning when planted in groups.
