While the flowers may not have an extended lifespan, their stunning appearance is worth the effort. These heirloom poppies are known for their striking presence, growing to a height of 0.9-1.5 meters (3-5 feet), depending on the richness of your soil. Their large, lettuce-like, blue-gray leaves complement the rich color of the flowers, making this variety the highlight of your spring garden. For the best results, harvest these poppies when they are approximately half-open. To prolong their freshness, sear the bottom end in boiling water for 7-10 seconds.
