Species: Lauren’s Grapes ( Papaver Somnefinum) Otherwise know as bread poppies. Excellent for seed harvesting for dressings, breads, and muffins! Beautiful purple flowers! Seeds need cold stratification. For best results, plant in the late fall or early winter. Clear and loosen a patch of soil, and lightly press into the top soil. Thin plants out in the spring for larger flowers. They do not transplant well. Plant in full sun.
