Mammoth Dill Seeds

Mammoth Dill is the classic giant dill variety prized for its towering growth, abundant aromatic foliage, enormous flower heads, and heavy seed production. Often growing 4 to 6 feet tall under favorable conditions, Mammoth Dill is one of the most productive and impressive culinary herbs that can be grown in the garden.

This heirloom favorite produces masses of finely divided, feathery blue-green foliage with the distinctive fresh dill flavor cherished in pickles, seafood dishes, soups, sauces, salads, potatoes, and vegetable recipes. As the season progresses, plants develop huge umbrella-shaped clusters of bright yellow flowers that are highly attractive to pollinators and eventually mature into abundant seed heads.

Mammoth Dill is considered one of the finest varieties for pickling because both the leaves and seeds can be harvested. The large flower heads are traditionally used in homemade dill pickles, while the seeds are collected for seasoning breads, soups, sauerkraut, spice blends, and countless culinary dishes.

The impressive flower umbels also make Mammoth Dill one of the best herbs for supporting pollinators and beneficial insects. Bees, butterflies, hoverflies, parasitic wasps, and other beneficial garden insects flock to the nectar-rich blooms. The plant is also a favored host for Black Swallowtail butterfly caterpillars.
