Twenty-five years in the making by renowned New Zealand breeder Keith Hammett, Lathyrus odoratus x belinensis ‘Erewhon’ is a sweet pea vine that truly turns expectations upside down. Its remarkable reverse bicolor blooms feature blue-purple wings and a pink-lavender banner, creating a dreamy, painterly effect that feels rare, romantic, and completely garden-heart-thumping.

Also known as Erewhon Sweet Pea, this fragrant annual climbing vine is a treasure for trellises, fences, obelisks, arbors, cutting gardens, and cottage garden plantings. Growing up to 8' tall, it brings wonderful vertical interest and produces sweetly scented blooms that are beautiful in bouquets. In hotter inland gardens, a bit of light shade can help bring out the richest flower color and keep the display looking its best.

Plant Lathyrus odoratus x belinensis ‘Erewhon’ in rich, well-drained soil with regular water and sturdy support for climbing. Cut flowers often and remove seed pods to encourage longer bloom. It may self-sow where happy. Explore more fragrant climbers in our Lathyrus - Sweet Pea collection.
