Can't be sure if this is a product of the Canadian based "Overgrow" campaign....
......but this one is growing in a weedy graveled parking area in a wildoats/dandelion thatch common to northern prairie urban. Had to have been thrown there on the surface of basically what I can only describe as hard-pan soil. It's the second one that popped up there so far.
