Fabaceae: a downy or hairless perennial to 75cm. found in grassy places but also cultivated. The flowers are purple and are in stalked heads of 5-40, blooming from June-September. The pods are spirally twisted. Trifoliate leaves. A widely naturalised as a relic of cultivation. Native to the Mediterranean.
The leaves and young shoots can be eaten raw or cooked. The leaves can also be dried for later use. Very rich in vitamins, especially A, B and C, they are also a good source of protein. The leaves are a rich source of vitamin K. A very nutritious food in moderation. The plant contains saponin-like substances, and the eating large quantities of the leaves may be potentially harmful. The seed is commonly used as a sprouted seed which is added to salads, used in sandwiches or cooked in soups. The seed is soaked in warm water for 12 hours, then kept moist in a container in a warm place to sprout. It is ready in about 4 - 6 days.
The plant has antiscorbutic, aperient, diuretic, oxytocic, haemostatic, nutritive, stimulant and tonic properties. It should not be used by people with auto-immune diseases such as rheumatoid arthritis.
Plants are very deep rooting, descending 6 metres or more into the soil, and are able to fix large quantities of atmospheric nitrogen. Often grown as a green manure.
A very versatile plant that can adapt to a wide range of climatic conditions from cold temperate to warm sub-tropical. It succeeds on a wide variety of soils, but thrives best on a rich, friable, well-drained loamy soil with loose topsoil supplied with lime. Pre-soak the seed for 12 hours in warm water and then sow in spring in situ. The seed can also be sown in situ in autumn. Easy.
