If it doesn’t smell like parsley compare to Bidens bipinnata L. – Spanish needles http://plants.usda.gov/java/largeImage?imageID=bibi7_008_avp.tif

Forgot to include…Black swallowtail caterpillars love parsley and I’ll be you will see them or the butterflies coming around if it is parsley.

Thanx a lot. I’ll smell it.

It could be a flat leafed parsley, but there is a lot of things that could look like this. A lot of caterpillar activity could signal that it is indeed parsley. Smell, parsley smells very grassy, like a fresh mowed lawn. Hope this helps.
