Beach pea is a hardy climbing perennial native to Great Lakes and Canadian regions, preferring cool, moist conditions with partial sun and well-drained soil. Provide a trellis or support for its tendrils to climb, and water consistently to keep the root zone moist but not saturated. This species is best suited to naturalized or coastal garden settings rather than formal beds.
