An Old World native, Yellow-horned Poppy was observed naturalized along the New England coast as early as the seventeenth century. Thomas Jefferson planted seeds at Monticello in an oval bed southeast of the house in 1807. This unusual biennial, sometimes a perennial, has curious yellow flowers and strange "horned" seed pods. It also has attractive bluish-gray, or glaucous, leaves that are most ornamental.
Predominately a summer bloom, the Yellow-horned Poppy sometimes flowers in October.
