  • Overview

    Italian Large Leaf Basil is a classic heirloom herb prized for its broad, tender leaves and intensely aromatic, sweet basil flavor with subtle hints of anise and pepper. Reaching maturity in approximately 74 days, this variety produces robust plants suited for full sun to partial shade conditions. The large leaves make it exceptionally practical for culinary applications—ideal for fresh use in pesto, Italian dishes, and salads. Unlike compact basil varieties, its generous leaf size reduces preparation time while delivering the authentic, complex flavor profile that defines traditional Italian cooking.
