Inula helenium Ann Arbor Natural Area Preservation

Roadsides, fields, trails and clearings in forests; occurs in both dry and wet ground. Apparently native to central Eurasia, but widely spread as an escape from cultivation, as it is both ornamental and medicinal. First collected in Washtenaw Co. in 1861.

This is a robust, large-headed perennial, up to 2 m tall. The massive root has long been revered for its medicinal properties, and the enormous leaves may at first glance be mistaken for those of Silphium terebinthinaceum.
