Elementary botany, series A.
The leaves of wild carrot (Daucus carota), caraway (Carum carvi) and yarrow (Achillea millefolium) are quite different from one another. Check it out for yourself:
Pic: The leaves of carrot, caraway and yarrow - but which is which? And no, they're not in the mentioned order.
The yarrow has been used as a culinary herb, but frankly, if you can find anything else even remotely edible around, pick that instead.
The caraway leaf is delicious. Caraway is native to Finland, but I grow it in my garden; that way, I'm guaranteed an abundant supply of lush large green caraway leaf throughout the season. It tastes of parsley at first, but if you leave things (breadspreads, for instance) in the fridge overnight, it gets a hint of caraway, too.
Dunno if you can use the leaf of wild carrot. I know that some make a soup with the greens of normal carrots, but I haven't done that, myself, either.
