Beach Pea (Lathyrus maritimus) is a legume with many other names: sea pea, circumpolar pea, and sea vetchling. The flowers are broad with a dark purple standard petal and paler purple and white keel and wing petals.
These beach peas were on the shore at Bratahlid, Eric the Red's hillside estate on a fjord on the south western
coast of Greenland. Sea peas have a large worldwide distribution because of the capacity of its seeds to maintain viability in sea water for over 5 years.
