unidentified herbal object: Volunteer sorrel?

[Mrs J B]

I planted cabbages and sorrel for the first time last year. Fell on my head and wasn't able to take care of garden, so some things didn't happen. Didn't see any sorrel come up in the jumble, but this year I have a wintered-over cabbage and what appears to be a sorrel. Leaves look more or less right for a sorrel, and it has a mild lemony taste. I thought sorrel had a little more of a kick. Thanks to the ridiculous growing season we've had so far, the sorrelly-looking thing already had flower buds on it. Anybody experienced with sorrel please give me the benefit of your experience.

Sorrel is a perennial, so it could be. The lemony taste is right, and it is more mild when the leaves are young, should become stronger as they get bigger. Mine has disappeared, I am planting more this year myself, I love sorrel.
