Lathyrus odoratus ‘Watermelon’ is a fragrant sweet pea vine with fresh, rosy watermelon-colored blooms that bring soft romance and springtime perfume to the garden. Its ruffled flowers are beautiful on the plant and even better in bouquets, where their scent and color feel wonderfully old-fashioned.

Also known as Watermelon Sweet Pea, this annual climbing vine is perfect for trellises, fences, obelisks, arbors, cutting gardens, and cottage garden plantings. Give it sturdy support and let the twining stems climb, bloom, and create a vertical curtain of fragrant flowers. The warm pink tones pair beautifully with cream, lavender, apricot, navy, burgundy, and other heirloom sweet peas.

Plant Lathyrus odoratus ‘Watermelon’ in full sun to light afternoon shade with rich, well-drained soil and regular water. Cut flowers often and remove seed pods to encourage a longer bloom season. Sweet, graceful, and bouquet-worthy, this fragrant sweet pea is a spring garden treasure. Explore more climbing favorites in our Lathyrus - Sweet Pea collection.
