Everlasting Sweet Pea
Everlasting Sweet Pea is a perennial vine that transforms ordinary garden structures into cascading displays of colorful blooms year after year. Hardy from zones 3 to 11, this open-pollinated Lathyrus latifolius reaches 5 to 6 feet tall and produces magnificent flowers that return season after season without replanting. Unlike annual sweet peas that fade after one year, this variety lives up to its name by rewarding patient gardeners with reliable, long-lasting color once established in its second year of growth.

Highlights
Everlasting Sweet Pea produces dazzling, colorful blooms that blanket vigorous 5 to 6 foot vines, delivering reliable flowers from year two onward. The perennial nature means no replanting required; once established, it becomes a permanent garden fixture that climbs fences, trellises, screens, and mailboxes with minimal fuss. Its extreme cold hardiness (zone 3) combined with heat tolerance through zone 11 makes it one of the few flowering vines that truly works across diverse climates.
Common Uses
Everlasting Sweet Pea excels as a flowering vine for vertical garden structures. Plant it to climb and cover fences, trellises, screens, mailboxes, light posts, and banks. The abundant blooms provide cut flowers for arrangements, though the primary appeal is ornamental garden coverage and long-season color.
