Notes
'William Willson' sweet pea (Lathyrus odoratus 'William Willson') is a vine for borders, containers, cottage gardens, and privacy screens. It is hardy to USDA zone 2, or down to -50°F (-46°C). This plant likes full sun and average to moist soil. It grows fast and has a broad habit, so give it a trellis or fence to climb. Fragrant flowers appear in spring and again in summer, and butterflies visit them.
Pairs well with Sonja sunflower, Charm peony, and Red fescue.
