I reckon if my late mother had been presented with a cannabis plant she would have put in one of her colourful pots, and put it on display for everyone to see, not having a clue what the plant was.
I used to joke that one of our former neighbours must be growing cannabis plants as winter and summer their upstairs windows were closed and the blinds drawn. None of the neighbours had ever been invited into the property during the three years that they occupied the place.
