Italian Large Leaf basil (Ocimum basilicum) is a classic sweet basil with big, tender leaves and a rich, mellow aroma. These non-GMO Italian basil seeds produce vigorous, upright plants whose broad leaves are ideal for pesto, sauces, and layering fresh onto pizza. It is the quintessential culinary basil for any kitchen garden.

Who it's for

A must-grow for home cooks and pesto lovers who want large, flavorful leaves and gardeners looking for a reliable, productive summer herb.

How & when to plant

Start indoors 4–6 weeks before your last frost, or direct-sow once soil is warm and nights stay above 50°F. Sow 1/4 inch deep, spacing plants 10–12 inches apart in full sun (6+ hours). This tender annual grows well in USDA zones 4–10; keep soil evenly moist and pinch growing tips to build a full, bushy plant.

Harvest

Leaves are ready to pick in about 60–75 days. Harvest from the top by pinching stems just above a leaf pair, taking up to a third of the plant at a time. Removing flower buds as they appear keeps the leaves tender and the plant producing into fall.

Benefits & uses

The large, sweet leaves are perfect for pesto, tomato sauces, caprese salad, and fresh garnishes. Plant generously for a steady kitchen supply, or succession-sow for fresh basil all season.

FAQ

Italian Large Leaf Basil produces big, tender, sweet leaves that are perfect for pesto, Caprese salad, and layering onto pizza and pasta. Its large leaf size means fewer leaves fill your bowl faster.
Plants grow about 24 to 30 inches tall with a bushy, upright habit and leaves that can reach 3 to 4 inches long. Regular pinching keeps it full and productive.
Start indoors about 6 weeks before the last frost or sow outdoors when the soil is warm, at least 65 to 70 F. Sow seeds about 1/4 inch deep in full sun and keep evenly moist until they sprout.
This is a generous packet of roughly 4,050 seeds, far more than most gardeners need in one season. Sow what you need and store the rest cool and dry for future plantings.
Thin or transplant seedlings to about 10 to 12 inches apart. Good spacing gives each plant airflow and room to build the large leaves it is known for.
Harvest from the top down and pinch off flower buds as soon as they appear, since flowering signals the plant to slow leaf growth. Frequent picking keeps it bushy and productive right up to frost.
Yes. Its large, sweet, tender leaves make it an excellent choice for pesto, sauces, and fresh Italian dishes.
