Would it be possible to identify the flowering white plants in the two included photos. These have appeared for the first time this year. We have recently cleared some plants from this tree line in our back yard and it now gets more sunlight than before. I just want to make sure they are neither invasive nor harmful. We used to have a lot of wild honeysuckle here but have tried to eradicate it. This does not look like honeysuckle to me but I have no idea what it actually is. Thanks for your help.

the shrub is White Snakeroot, Ageratina altissima. The following website will provide more information on this orally toxic North American woodland perennial.
