About

Eutrochium is a North American genus of herbaceous flowering plants in the family Asteraceae. They are commonly referred to as Joe-Pye weeds. They are native to the United States and Canada, and have non-dissected foliage and pigmented flowers. The genus includes all the purple-flowering North American species of the genus Eupatorium as traditionally defined, and most are grown as ornamental plants, particularly in Europe and North America.

Uses

All of the Joe Pye weed species except E. steelei are widely cultivated as ornamental landscape plants. Cultivars have been developed for a more compact habit (e.g. E. dubium ‘Little Joe’, E. dubium ‘Baby Joe’, E. maculatum ‘Little Red’) and varied flower color.
