Fennel

In the garden of herb names, Rosemary and Basil are perennials and Sage is a new upshoot, but Fennel is a real rarity. The aniseed-tasting plant, used to add flavor to dishes around the world, gets its name from the Latin word feniculum, meaning "little hay". With a wholesome nature feel and a similar sound to Finn, Fennel would be an interesting name to bring to the table.
