Lyn, you may be on to something- that certainly follows the standard logic. You've extended bloom on Ca. poppies by deadheading, right? It is surely worth a try with Papaver rhoeas and maybe Papaver somniferum too. How on earth does one pronounce the genus of Ca. poppy? California Poppy (Eschscholzia californica)- sounds like a cat sneeze when I try to say it! LOL
