Award-winner Lathyrus latifolius, commonly known as Everlasting Pea or Perennial Sweet Pea is a vigorous climbing perennial that produces racemes of 5-11 vibrant rose to white pea-like flowers, 1 in. across (2.5 cm). Blooming all summer, if not allowed to go to seed, the attractive blossoms are borne on winged stems clad with paired, blue-green leaflets bearing tendrils. They will ramble along the ground or climb up nearby vegetation or support structures. Unlike Lathyrus odoratus, the flowers of Everlasting Peas are not fragrant. Easy to grow, Lathyrus latifolius requires little care and enjoys some drought tolerance.
While native to the Mediterranean, Everlasting Peas have been grown in North America since 1700s where they have naturalized to such a point that they are now considered to be invasive in some areas.
