Could be money plant? The ones in my yard have just shut down and set seed, but I still see some blooming around the area. You often see them in waste areas or growing under large shrubs where mowers can't reach.

Although I've not seen them (I try to keep to the back roads), I'm going to bet it's dame's rocket - which is considered to be invasive although I love it.

I had some for a while then it disappeared. I noticed a patch today at work and thought maybe I'd take a clump to try to get it started again.

NJ Tea - you might be right, I hadn't thought of that.

Dame's rocket it is. I read that it is an ornamental gone wild and is very invasive in New Jersey. But it sure is pretty, isn't it?

Thank you!

I'm in Metuchen and commute to Hunterdon County, and have noticed them, too!

My favorite is along Rt. 78, between 287 and Lebanon. They have beautiful purple and white wildflowers, that kind of look like poppies, growing all along the median. They haven't started blooming yet, but it's nice to see them!
