Illustration of Beach Pea (Lathyrus japonicus)

Beach Pea is a trailing vine that grows on sandy ocean beaches, lake shores, and gravel bars across northern North America. Its showy purple-pink flowers are a surprise in the harsh beach environment. It fixes nitrogen, helping build soil on newly formed dunes and shorelines. Bumblebees are the primary pollinators.

Habitat
