Eupatorium is a genus of flowering plants in the family Asteraceae, commonly known as the aster or daisy family. This genus includes a variety of species, many of which are native to North America and Asia. Eupatorium plants are typically characterized by their clusters of small, tubular flowers and can be found in diverse habitats, including wetlands and meadows. Some species of Eupatorium, such as Eupatorium purpureum (commonly known as Joe-Pye weed), are valued for their ornamental qualities and attract pollinators like butterflies and bees. These plants often thrive in moist soil and can grow to significant heights, making them popular choices for garden landscapes and naturalized areas.
