The quintessential reseeding annual of northern climes is the poppy. Both
papaver rhoeas (shirley poppy, corn poppy), and papaver somniferum (opium

cold enough, iceland poppy may reseed itself too. (Native to arctic
regions).

Huh? Opium poppies are perennial, n'est-ce pas?

A friend gave me some root pieces in a pot..
planted them years ago...
the *exact same* poppy comes up every year...
not new seedlings.
