Joe Pye weed (Eutrochium purpureum) is a late-blooming wildflower that’s native to eastern and central North America. It generally grows in upright clumps that reach several feet tall. Its thick stems have lance-shaped, serrated dark green leaves that can be up to a foot long. And in the midsummer tiny mauve flowers bloom in large clusters atop the stems. These flowers have a sweet vanilla scent and are especially attractive to butterflies and other pollinators. Joe Pye weed is best planted in the spring after the threat of frost has passed. The plant has a fast growth rate.
There are no serious issues with pests or diseases. Powdery mildew is the most common problem that arises, a fungal disease that causes the foliage to become discolored with white splotches. Warm, dry climates and poor air flow can trigger it. Apply a fungicide promptly to prevent the powdery mildew from spreading, and remove infected portions of the plant.
Joe Pye Weed Care
Joe Pye weed is a fairly low-maintenance plant, and it’s quite rewarding to grow due to its notable size and fragrant blooms. It does need space when you first plant it to accommodate its height and spread. But it can look great planted along borders, in wildflower gardens, and at the back of plant groupings to provide height.
Joe Pye weed grows best in full sun to partial shade. Too much shade can impede growth and cause the plant to flop over. Shady conditions also can make the plant susceptible to disease. However, Joe Pye weed typically will appreciate some protection from hot afternoon sun, especially in the summer months. Too much strong sun can cause yellowing of the leaves.
Joe Pye weed is fairly hardy both to cold and to heat within the climates of its growing zones. Frost will cause the plant to begin dying back to the ground for the winter. Humidity (or lack thereof) typically isn’t an issue as long as the soil remains moist.
