Use: Use perennial sweet peas on a trellis, fence, shrub, or to cover a rough site or neglected areas. The perennial sweet pea climbs by tendrils and require support or they will readily form a mound by climbing on themselves or other plants. They produce good cut flowers, but they are not scented.
Culture: Perennial sweet peas are easy to grow and need little attention once established. They will tolerate a wide range of soil types and exposures, but grow best in full sun and well-drained soil. The flowering season can be extended by removing spent flowers.
