I found this list of weeds with known medicinal/magickal properties on my hard drive. They are all known to grow in urban settings (here on the west coast, at least, I’ve found most of them).
I can’t remember where I found this list, but it’s not entirely of my own compilation. (I’ve added a few things.) The file is over 3 years old. If it looks familiar let me know and I’ll credit it.
You’re welcome. 🙂
