Beach pea is a perennial, slightly fleshy, coastal plant growing in gravel and sand in spreading vines. It has alternate, pinnate leaves, each with with 2-lobed stipules at the base, 4-12 ovate leaflets and terminated with a tendril. The inflorescecne is a raceme with 5-12 blue-violet flowers. These are papilionaceous flowers typical of many Fabaceae species (peas, beans etc.). Each flower consists of 5 fused sepals and 5 petals including a broad erect petal at the top of the flower, two fused lower petals that form a boat-like structure surrounding the stamens and pistils, and two narrow lateral petals. Flowers apear in July through September in Nova Scotia. The fruit is a typical legume, with 2 valves that split open along 2 sutures but remain hinged at the base. Beach pea has a circumpolar distribution. In Canada it occurs in British Columbia and from Manitoba to Newfoundland.
