Round-leaf Boneset (Eupatorium rotundifolium) aka Round-leaf Thoroughwort - 2015-8-24 Newark, DE

This might be confused with White Snakeroot (Ageratina altissima) but where A. altissima has long petioles (leaf stems) E. rotundifolium has sessile leaves.

The plants database shows 4 subspecies of Eupatorium rotundifolium:

Eupatorium rotundifolium var. ovatum
Eupatorium rotundifolium var. rotundifolium
