Thought I'd post a photo of what these nasties look like from a distance. I hope it will help you identify them.
The garlic mustard is the tall, spindly looking stuff with white flowers. You can click the photo to enlarge it.
Now that I'm watching for it, I realize that this stuff is everywhere. It's along a lot of the roadsides around here, and there is a tree farm on my way home that has been completely taken over by it.
I have cleared everything along our driveway, which amounted to a garbage bag full. I still have this patch to go, and I need to get deeper into the woods to see if it's back in there. I'll try to get to that tomorrow, and to check the north woods. I don't recall seeing any back there, but I haven't been back to where it meets the fields, which is where it will start.
Another tidbit: The garlic mustard not only shades and crowds out all natives, it also exudes compounds from the roots that prevent both native wildflowers and young trees from growing. It truly is an evil, evil weed.
