My favourite "weed".

       First seen here, in the extra.  I re-found it in '17 and collected seed in August; manage to lose them all and found one plant a year or three later; in a crack in the cement beside "The Wagon".  There's now a second one in a corner of the Border. 
       Any ID I'd be grateful for.  Early on it seemed to be "Nettle-leaved bellflower - BUT - today when I looked I found THIS LOT & thought I'd keep it here.

IF it is an escapee the nearest habitation is, literally miles away.
