Native to China, it is one of (if not the) the most common invasive tree species in Philadelphia. It will grow out of cracks in the side of a building and grows rapidly, often destroying whatever it grows in.

It is, indeed. I love Solanums in general.
In the past, I'd only seen them occasionally in tree-pits, but last year I found two growing out of the sidewalk itself, that one and this little guy that didn't survive the foot traffic.

This adorable little Buffalo Bur (Solanum rostratum) didn't make it. This wasn't surprising with it sitting in a well-trodden spot. I have a few more good shots of it squirreled away for future winter posting.
