Cannabis sativa

Something I did not expect to see on a field trip at a conference. Guess this stuff can escape cultivation like other crops. There was only this little seedling, but it still left an impression. What craziness would happen if this plant became an invasive species?

Growing in Capitol Square tulip beds.

With urtica. Under pop grand/pru serotina. Several plants occurring for at least 3 years. East of section 7 marsh

I've been pulling weeds in public gardens for over a year now but this is a first.
