The fennel herb (Foeniculum vulgare) has a long and varied history of use. The Egyptians and the Chinese used it strictly for medicinal purposes and their lore was brought back to Europe by early traders. During the Middle Ages, it was believed to hold magical qualities and people hung fennel plants over their doors to drive away evil spirits. Eventually, someone recognized its use as a flavoring for eggs and fish. Today, its crisp anise flavor makes it a favorite of cooks everywhere.
Native to southern Europe, the fennel herb is now naturalized throughout Europe, North America and Australia and grown in gardens all over the world.
You’ll find two methods of propagation when researching how to grow fennel. Plants may be divided, but this isn’t as easy as it is with other garden plants and often proves unsatisfactory.

Fennel is a short lived perennial that blooms best in the second year. It readily re-seeds and while not considered invasive, it has certainly earned its reputation for aggressive growing. Fennel can be cut back early in the season to encourage bushier growth and should be deadheaded for seed harvest and to prevent over seeding of new plants.
Harvest and dry seeds as the flower heads fade. There’s only one restriction to how to grow fennel: don’t plant it near dill. Cross pollination results in strangely flavored seeds for both plants!
Once established, fennel herb doesn’t need much care. It prefers acid soil, appreciates the occasional dose of mild fertilizer and a little additional water if the weather is hot and dry.
In addition to its kitchen contributions, planting fennel will attract beneficial insects to the garden and its leaves are a favorite with the caterpillars of the swallowtail butterfly.
