This rare plant is also known as Horned Poppy. Glaucium 'Burnt Orange' has vibrant orange flowers in early to mid summer. The blue-gray leaves remain attractive throughout the season.
Glaucium corniculatum can be grown as an annual or a biennial, depending on when and where it is sown. In my zone 5 garden, it grows as a biennial, even when the seeds are sown early in the year. Easy to grow. Hardy in zones 6-9.
Sowing Glaucium corniculatum Seeds:
Sow outdoors in spring or late summer. Barely cover the seeds. Full sun.
