Fennel is widely employed as a carminative, to treat flatulence by encouraging the expulsion of intestinal gas. It is used as a remedy for coughs: has the ability to tone, strengthen, detoxify and heal the liver and increases bile production, thus aiding digestion. It's anti-inflammatory, anti-microbial and has actions against a range of bacteria as well as various fungi and yeasts. It can also help to improve eyesight.
Fennel is a valuable plant both as a nourishing vegetable and a medicine. It tastes great and is easy to grow. Originating from the Mediterranean, it can be grown as an annual vegetable, or as a perennial for its foliage and seed crop harvest.
Direct sowing is best, as the seedlings don’t take kindly to transplanting. Fennel prefers full sun with well-drained loamy soil. Although relatively hardy, plants are liable to die out over the winter if the soil is not well drained or the weather is persistently cold and wet. Root divisions tend to take well at any time through the growing season, although they never seem as robust as seed-sown plants.
Growing up to 10 feet, with its characteristic feathery foliage and yellow flower heads, fennel is a striking addition to any garden, with the added bonus of attracting a wide array of beneficial insects. It is generally a poor companion plant in the garden, inhibiting the growth of nearby plants, especially beans and tomatoes.
Late in the season, it’s easy to harvest dry brown seeds by rubbing them between your hands into a container. Both leaves and seeds make pleasant and soothing tea.
