Foeniculum vulgare Fennel Evergreen perennial (1 Page of 5) The Foeniculum vulgare plant species is found in S. Europe. Naturalized in Britain. It is a member of the Umbelliferae family. Common gardeners may know the plant as Fennel. Some home gardeners know the variety as F. officinale. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Foeniculum vulgare Common Name: Fennel Family: Umbelliferae Author: Mill. Known Hazards: Skin contact with the sap or essential oil is said to cause photo-sensitivity and/or dermatitis in some people[218, 222]. Ingestion of the oil can cause vomiting, seizures and pulmonary oedema[222]. Mature Height: 1.5 Mature Width: 1 Habitat: Found most often in dry stony calcareous soils near the sea[1, 16, 190].
Cultivation Notes: An easily grown plant, it succeeds in most soils but prefers a sunny dry position[4, 16, 37, 200]. It grows well in sandy soils[188] and is drought tolerant once established[190]. Plants often self-sow freely in the garden[K]. Plants can be grown in quite coarse grass, which can be cut annually in the autumn[233].
Although hardy in most parts of Britain, plants are liable to die out over the winter if the soil is not well-drained or the weather is persistently cold and wet[238].
Fennel is often cultivated in the herb garden for its edible and medicinal uses, there are some named varieties[183]. Especially in mild winters, the leaves can be available all year round[K]. It is best to cut a few plants back to ground level occasionally during the growing season, thus ensuring a constant supply of fresh young shoots[4]. In a dry summer make sure that you water the cut-down clump or it might not regrow that year[K]. Fennel is also grown commercially as a medicinal plant and for its essential oil[4, 238].
Fennel is in general a poor companion plant in the garden. It inhibits the growth of nearby plants, especially beans, tomatoes and kohl rabi[14, 18]. It is itself inhibited by wormwood and coriander[14, 18]. However, the flowering plant attracts beneficial insects such as bees, parasitic wasps, tachinid flies and hoverflies to the garden. The presence of these creatures will help to maintain a natural balance of insects in the garden and help prevent infestations by aphis etc[238].
It is best not to grow fenneal and dill (Anethum graveolens) close to each other since hybridisation can occur and the resulting seedlings will be of indeterminate flavour[238].
