Parsley is an annual and sometimes biennial herb in the
celery and
carrot family commonly grown as a garden vegetable and as food for black
swallowtail butterfly caterpillars. The root is also harvested as a
vegetable, the flavor of which becomes sweeter if left in the ground to
endure a hard frost.
Parsley root is a particular favorite root crop in German cuisine, where
it is fried, roasted, mashed or simply tossed into soups and stews.
Dried parsley root can also be decocted as tea or tinctured in alcohol
or vinegar.
