Lathyrus sylvestris - L.

Common Name Flat pea, Wood pea
Family Leguminosae
USDA hardiness 6-9
Known Hazards All parts of the plant, but especially the seed, contain a toxic amino-acid. It is produced in the plant at about the same time that the seed starts to develop. In small quantities the amino acid is innocuous, and the seeds of several Lathyrus species are eaten as a nutritious part of the diet. However, in larger quantities (the seed should form less than 30% of a balanced diet), it can cause a very serious disease of the nervous system known as 'lathyrism'. Symptoms appear as a paralysis of the muscles below the knees, pains in the back, followed by weakness and stiffness of the legs and progressive locomotive incoordination[65 , 76 , 1309 ].
Habitats Thickets and woods[17].
Range Eurasia - Norway through Britain to Spain, east to Western Siberia, the Caucasus and Greece

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

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

Lathyrus sylvestris is a moderately cold-hardy plant, able to tolerate temperatures down to around -20?c when fully dormant[200 ]. Grows well in full sun and in light, dappled shade, succeeding in most moderately fertile, well-drained soils[200 ]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[1309 ]. Suggested planting locations and garden types: Forest garden, Flower borders and beds Wall-side Borders Cottage & Informal Garden City & Courtyard Gardens. May be attacked by aphids, slugs and snails.
