So, this might just be my ignorance (and the ignorance of the internet after an as thorough as I could be bothered search), but I used to believe that there were two types of parsley around. Then I planted both flat and curly leafed parsley for this year and, well, got what seems to be three varieties. Apart from the oddly shaped leaves and a higher, less bushy growth it looks, and tastes, like parsley. So, any ideas of what variety it might be, or is it just an odd mutation of some sort? (It would, of course, be the leaves to the left of the image, the ones that do not belong to the flat or curly leaf plants.)

Thanks!
