I was interested to know how common wild white poppies are.
OK, that I can work with.
Papaver rhoeas is probably not a UK native, but has been growing here for as long as grain has been farmed. Which makes it a synanthropic archaeophyte.
As a cornfield 'weed' it has become scarce, primarily through better automated seed cleaning even though the use of selective herbicides can't have helped.
Pure 'wild' forms probably no longer exist, with pollen transfer from garden selected colour forms contaminating all 'wildflower' mixes.
White poppies occured in Flanders Fields often enough to be visible. But you would only need one white one in a field for it to show up.
In an urban environment, as is your example, there is a high probability that they, or their parents, are from horticultural stock, so colour variants are even more likely.
