Sweet Pea 'Blue Vein'
Lathyrus odoratus

Blue Vein is one of those varieties that stops you in your tracks. It begins as a soft coral bloom—but as the flower matures, something magical happens: fine blue-purple veining emerges across the petals, like watercolor brushstrokes slowly revealing themselves with time. It’s a bloom that transforms before your eyes.

Bred by Dr. Keith Hammett, this sweet pea may be petite in size, but it carries a beautiful classic fragrance and a uniquely artistic presence in the garden or in the vase.

Because Blue Vein changes so much as it ages—and is notoriously tricky to photograph—I’ve added plenty of pictures to help you get a sense of its metamorphosis. Every bloom tells its own little story.

If you love flowers with movement, nuance, and a bit of mystery, Blue Vein is a must-grow.
