The Beach Pea, or Sea Pea, with its bluish grey leaves and large flower, may be one of the most ornamental beach species. This beauty is only enhanced in the wild: the likeliest place to find it is on sandy and gravelly sea-shores, where it grows as a pioneer some distance from the water line, just out of reach of the waves. Sea pea typically grows in half-open places and can hold its own for quite a long time amidst encroaching vegetation, even on the edge of forests. The fruit is 1 /12 - 2 inches long and is said to be edible when young if properly prepared. L. japonicus was eaten by all sorts of groups that lived along the seashore, from the Eskimo to the Iroquois. Very hardy, all the way up to Alaska. Zone 3a - 8b.
