Edible Uses
Edible Parts: Flowers Leaves Root Shoots Stem
Edible Uses: Condiment
Leaves and young shoots - raw in salads or cooked in soups, stews etc[2, 5, 8, 12, 27, 37, 115, 183]. The plant comes into growth in the autumn and the leaves are often available throughout the winter[5, 52]. They have a rather strong celery-like flavour and are often blanched (by excluding light from the growing plant) before use[183]. Leafy seedlings can be used as a parsley substitute[183]. Stem - raw or cooked[2, 5, 8, 12, 27, 37, 53, 115]. It tastes somewhat like celery, but is more pungent[17, 244]. The stem is often blanched (by excluding light from the growing plant) before use[183]. Flower buds - raw[12, 52]. Added to salads, they have a celery-like flavour[K]. The spicy seeds are used as a pepper substitute[52, 183]. Root - cooked. Boiled and used in soups, its flavour is somewhat like celery. The root is said to be more tender if it has been kept in a cool place all winter[183].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details
Succeeds in most soils but prefers an open sunny position in a well-drained moisture retentive soil[200]. Hardy to about -15°c[200]. At one time this plant was extensively grown for its edible leaves and stems but it has now fallen into virtual disuse, having been replaced by celery[1, 2, 27, 37, 61, 183]. The seeds are highly aromatic with a myrrh-like scent[245]. A good bee plant. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is fleshy. Thick or swollen - fibrous or tap root [2-1].
