Title: Identity of plant with white flowers and serrated leaves in creek bed
Answered by: Nan Hampton

QUESTION:

I have a wild fall blooming plant, white flowers, serrated leaves. Growing abundantly in my dry creek bed. Any thoughts?

ANSWER:

My best guess is that it is either Ageratina havanensis (Havana snakeroot or shrubby boneset) or Ageratina altissima var. altissima (White snakeroot).   Here are more photos and information about A. havanensis from the School of Biological Sciences, University of Texas and Flora of North America and here is more about A. altissima var. altissima from Native and Naturalized Plants of the Carolinas & Georgia and Flora of North America.

If neither of these looks like your plant and you have (or can take) photos of it, please visit our Plant Identification page to find links to several plant identification forums that will accept photos of plants for identification.
