Sweet Joe Pye Weed (Eutrochium purpureum), also known as Gravel Root, is a large clumping perennial that injects architectural interest into the late summer landscape. This robust wildflower has multiples of sturdy stems with whorls of attractive foliage. In mid-summer, plants are topped with a frothy crown of rounded rosy pink flower clusters. The vanilla scented blooms are frequented by butterflies.
It is native to northwest, eastern and central North America. Many people think of Sweet Joe Pye Weed as a weed found in the ditches along the side of the road. But is a stunning perennial in the back of a border or cottage garden, and particularly in meadows or native plant gardens. It just needs space to grow as the stand can reach heights of up to 10 feet (3 m) and widths of up to 5 feet (1.5 m). It also works great in rain gardens, or even at the edge of ponds or streams.
In the Language of Flowers, Sweet Joe Pye Weed is said to mean Delay. It is sometimes cultivated and has escaped from cultivation in parts of New Zealand.
