Really, the nerve of this thistle! It is growing in a tiny crack between a concrete wall and the asphalt of a parking lot. I have tentatively identified it as a sowthistle (sonchus oleraceus.) If I am incorrect, please let me know.
I estimate that this plant is about 4-1/2 feet in height -- close to the top of the normal height range of sowthistles. It is doing quite well despite the confines of its existence.
Sowthistles are members of the aster family. The flower of this plant does look like an aster bloom. The tenacious and prolific ways of the sowthistle have put it on the noxious weed list in 20 U.S. states and 5 Canadian provinces.
