Marsh pea, Slender Stem Peavine, Lathyrus palustris

marsh peaA good plant for the bog or marsh garden, succeeding in wet soils.

The seed can be eaten cooked. The fully grown seeds are shelled and cooked as a vegetable.

Although no records of toxicity have been found for this plant, the seed of some species in this genus contain a toxic amino acid that can cause a severe disease of the nervous system known as 'lathyrism' if they are eaten in large amounts (although small quantities are said to be nutritious).

Young leaves and stems are  edible cooked.

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.
