On my way to and from work I see this weed: it resembles dill, angelica, etc. in that the flower is a cluster, umbel. The color of the whole plant, flowers and all, is a lime green/yellow-green. I've done searches for all the plants I know that might look like what I see, but the color is what's throwing me off. Nothing that turned up in my searches matches what I see as far as color. As far as I can tell, in size it ranges from two feet to maybe four feet tall. Hard to say since I'm usually traveling 50mph when I see it.
Unfortunately, since I see this plant from the car on a busy road I can't describe the leaves or even take a picture. I'm hoping that someone will read this and recognize it right off the bat.
