Virginia Buttonweed (Diodia virginiana)
I hate this stuff. Sure, it may look all sweet and innocent in the photo, but this weed is a tenacious lawn-destroyer. It likes wet areas and started growing next to my birdbath a few years ago. Not realizing how evil it was, I did nothing until last year. By then it had spread out over several feet, and even started growing in a completely separate section of my yard.
I used Bayer’s Weed Control spray last summer, which destroyed everything above ground level but didn’t kill the roots. The buttonweed is back this year and I’ve been trying to remove it by hand, which I read is the preferred method of control.
