Is "pot plant" a term you would use for any plant with its roots in a pot

Amazingly enough, yes, TEd

You see, we never call the plant with the interesting and distinctive leaves that you've seen in pictures "pot" - it's "grass" or "weed" or "skunk". Um, I believe.

In resinous form it's "hash" or "dope", although you do get people talking about "dope plants" just to confuse matters.

I've only ever heard USns and misled oldsters (trying to look with it) call it "pot".

waiting to be corrected by Rhuby!
