Well, a lot of herbaceous weeds will grow out of cracks but not bust them open, so that term should be used selectively but would apply here. I also use the more neutral term crackplant.

I was so wrapped up in focusing on the Saltmarsh Goldenrod and Eastern Baccharis the first time I visited this site that I didn't even notice that the Tree of Hell (Ailanthus altissima) was a giant crackweed just off to the side. In my defense, there were cars there the first time. #WeedTrees

I thought we were past blooming season for Bastard Indigo (Amorpha fruticosa) but I guess that isn't exactly the case, as I shot this today along the Delaware River.

I think I have around a hundred shots of Chicory from this same median with the skyline. There are usually a few plants there & they keep getting cropped & growing back. There are currently 3 versions up on Redbubble. #2 is my favorite. www.redbubble.com/shop/ap/1836...

It was rough to get a shot that worked, the shadow/light contrast was so severe.
