Sweet Pea - Perennial

Perennial sweet pea is a rhizomatous legume that is used extensively as ground cover for erosion control and beautification purposes. It develops tendrils that will allow the plant to climb, though on its own will only grow up around two feet tall. It produces coarse foliage and requires 25-65 inches of annual rainfall per year. The plant roots will grow as deep as twelve inches below the surface, providing significant soil stabilization. Perennial sweet pea is adapted to medium and coarse soil textures, has high drought tolerance, and requires moderate soil fertility. If broadcasted, the seed should be covered with a fine layer of topsoil or mulch, or harrowed in. Successful germination will only result it if is fully encapsulated within the soil. Consider planting this species with a companion grass for better ground cover.
