Lathyrus littoralis
Also called Dune Sweet Pea, Grey Beach Pea, Grey Beach Peavine, Silky Beach Vetchling, Strand Sweet Pea, Gray Beach Pea
A native coastal wild pea of western North American beaches and dunes, forming a low, sprawling perennial with pink and white flowers. It needs full sun, sandy well-drained soil and little water once established.
Lathyrus littoralis is a species of wild pea known by the common name silky beach pea. It is native to the coastline of western North America from southern British Columbia to California. It is a resident of beaches and dunes.
This is a perennial herb which grows a patch of hairy gray-green stems along the sandy ground or slightly upright. The woolly leaves are made up of several oval or oblong scoop-shaped leaflets. There are small, tough tendrils but the plant does not use them to climb. The plant produces dense inflorescences of several flowers each one to two centimeters wide. Each flower is bicolored in dark-veined deep pink and white. The fruit is a dehiscent oval-shaped hairy legume pod. It blooms from late spring to early summer.
