Long Island Mammoth Dill, Heirloom Seeds

Grow a classic pickling dill with fragrant, feathery leaves and broad yellow flower heads. Long Island Mammoth brings fresh dill flavor to cucumber pickles, potato salads, fish, soups, cheeses, and omelets. Let some plants flower for pickling heads and mature seed, while harvesting foliage from younger sowings for everyday cooking.

Why Grow Long Island Mammoth Dill?

• Three useful harvests: Pick leafy sprigs, gather immature flower heads for pickling, or wait for ripe seed to use as a spice.
• Fragrant kitchen-garden foliage: Snip just what you need for sauces, salads, and warm dishes.
• Upright garden presence: Fine-textured leaves and yellow umbels add height to herb beds and vegetable gardens.
• Open-pollinated heirloom: A traditional dill selection grown for leaves and seed heads.

Growing Notes

Direct sow around the last frost date in full sun and loose, well-drained soil. Cover seed about ¼ inch deep and keep the seedbed evenly moist until seedlings establish. Germination usually takes about 10–14 days in suitable conditions. Thin to 12–18 inches apart, allowing extra room for flowering plants. Direct sowing avoids disturbing the developing taproot.

Sow small batches every 2–4 weeks while conditions are suitable to extend the supply of tender leaves. Flowering reduces leafy growth, so keep some plants for foliage and others for flower heads or seed. Fall sowing is an option where the remaining season allows plants to establish before severe cold. Water during dry spells and support tall flowering stems if exposed to wind.

Harvest Details

• Leaf and flower harvest: Approximately 60–70 days from sowing for developed plants; light leaf picking can begin once plants are well established.
• Ripe seed: Allow additional time after flowering. Gather heads when seeds turn brown, before they shed.
• Plant habit: Upright annual with feathery foliage and yellow flower umbels; commonly about 24–36 inches tall, potentially taller in favorable conditions.
• Seeds per packet: Approximately 200+ seeds, as currently listed.
• Packet weight: 0.1 g, as currently listed.
• Square foot spacing: 1 plant per sq ft, with extra canopy room for mature flowering plants.
• Botanical name: Anethum graveolens.
• Season: Grown as an annual; planting dates depend on local frost and heat.

From Garden to Kitchen

Add fresh leaves near the end of cooking to enjoy their bright aroma. Use immature flower heads for classic dill-pickle flavor, and save fully mature seed for breads, soups, and spice blends. Plants may self-sow if seed falls, but a fresh sowing is the better way to plan the next crop.
