Definition of "poppy"

In Flanders fields the poppies blow / Between the crosses, row on row, / That mark our place; […] / If ye break faith with us who die / We shall not sleep, though poppies grow / In Flanders fields.

We cherish, too, the poppy red / That grows on fields where valor led; / It seems to signal to the skies / That blood of heroes never dies, / […] / And now the torch and poppy red / We wear in honor of our dead. / Fear not that ye have died for naught; / We've learned the lesson that ye taught / In Flanders fields.

I thought Sparks were great; they were very poppy for Island Records. They were considered an oddity but you have to remember that at the time Roxy Music, now everyone's seminal band, were seen as very poppy.
