Dill seed

The seeds have a much more potent flavor, similar to a combination of anise and celery. The flat, yellow flower umbels of late summer give way to the seeds in fall. These can be used in breads, stews, rices, root vegetable dishes and most notably, the making of pickles. These seed heads, when combined with vinegars, garlic, sugar, salt, and pepper produce the dilled pickles that have that wonderfully puckery quality.

Medicinal Uses: So whether it is used to cure hiccups and colic, fight aphids in the garden, or turn a fresh side of salmon into a tasty Scandinavian appetizer, dill remains a delicate, calming addition to the home gardener.
