Description

Eutrochium purpureum is a tall, clumping perennial that is sure to create an impression in the garden. Growing up to 8', the stems are erect, sometimes branched, and can be distinguished form other Joe-Pyes by the purplish hues at the nodes. The leaves are large, up to 6' long, pale-green, and whorled around the stem in groups of 3 or 4. The terminal flower clusters are also large, and very showy. Bloom color may vary, but is typically pale shades of pink or purple. In fall, the flowers give way to attractive, fluffy seed clusters that will persist into winter. Both the foliage and the flowers emit a light fragrance reminiscent of vanilla, hence the common name sweetscented Joe Pye weed.

Cultivation

Easy to grow and adaptable, Eutrochium purpurium is more shade tolerant than other Joe Pyes. It does best in part-sun to part-shade, and prefers moist to mesic, rich, well-drained soil. It can be grown in typical garden conditions, and is worry free. Given its size, it should be given enough room to grow, however, it is not an aggressive plant, and its shallow fibrous root system will not interfere with other garden perennials. It can also be used to dramatic effect planted in masses in naturalized areas. The blooming period lasts about a month, between mid-summer to early fall. Zones 4-8

Propagation

Propagate from seeds in fall. They should be sown thick because germination rates are low. Softwood cuttings can be made in spring. Root division should be done when the plant is dormant, either in early spring, or fall.

Additional Notes

Eutrochium purpureum is often confused with E. maculata which has purple stems. It can also be confused E. fistulosum which has hollow stems.
