Harvested from the gardens at Monticello! This unusual short-lived yet self-seeding perennial – native to the coastal regions of North Africa, Europe, Britain, and Western Asia – was observed naturalized along the New England coast as early as the 17th century. Thomas Jefferson planted seeds of Yellow Horned Poppy at Monticello in an oval bed southeast of the house in 1807. It has attractive, bluish-gray foliage and bears bright golden-yellow, poppy-like flowers followed by strange, “horned” seed pods.
Sow seeds indoors 10-12 weeks before last frost; keep the seeds at 35-40°F for 3-4 weeks, then move to 65°F. Transplant to 3” pots once they have several true leaves, then harden off and plant outdoors after last frost in well-drained to dry soil. Approximately 20-25 seeds per packet.
