Organic Dill Seeds Heirloom Herb. Organic dill seeds produce a plant that should be a part of any herb garden. Seeds grown from the plant and foliage can be used to flavour foods and are especially important in the flavouring of vinegar and pickles. Dill is regularly used in gardens as a quick growing attractant for beneficial insects such as lady wings, lady bugs, hover flies and parasitic wasps as well as a food source for butterlies and other pollinators.
