Fennel (Foeniculum vulgare) is an herb grown both for culinary purposes and for it’s ornamental value. It’s feathery, branching, aromatic, yellow-green foliage and tall stature can be attractive as border plantings, in cottage gardens and more. It is also a good choice for butterfly gardens, as swallowtail caterpillars use it as a food source and pupal site. The plant sports small yellow flowers in the summertime, followed by aromatic seeds that can be harvested along with the foliage. It has a flavor similar to anise or licorice. Fennel is typically planted in the spring and it has a fast growth rate.
