Growing Mammoth Long Island Heirloom Dill

‘Mammoth Long Island’ is an heirloom dill prized for its vigorous growth, large flower umbels, and abundant seed production. Tall productive plants are especially useful for gardeners who want generous quantities of both fresh dill foliage and mature seeds.

Ready to begin harvesting in about 70 days, cut fresh foliage as needed or allow the large umbels to mature for seed harvest.

Aromatic, vigorous, and productive, ‘Mammoth Long Island’ is excellent for pickling, drying, fresh cooking, and seasoning.
