I do have a patch of weeds in my garden. It is in the dogs area and not easily seen unless you are really looking for something. This is the sign I posted there.
I made one for a friend that says 'Exotic Herb Experimental Station'. She says people often want a start of her 'herbs'. I told her that since most weeds have medicinal properties to sell them a few.
I am a bad, bad person...... but I laugh a lot!
