Little Weed?

A lazy day after yesterday spent in the garden. I've been waiting for this poppy to flower for days, and today it obliged.

The poppy first appeared out of nowhere many years ago, and self seeds every year. It is gradually 'walking' round the garden, and this year has seeded itself in the veggie patch. One definition of a weed is a plant in the wrong place, hence my dilema. However, it is such a pretty flower, so I think I'll let it stay put!
