About

Argemone albiflora is a biennial or annual plant characterized by its erect growth and spiny, dark blue-green leaves. Throughout the summer, it produces sizable, white flowers reminiscent of poppies, each featuring a center that ranges from yellow to red. When the foliage is damaged, it exudes a milky sap. While each flower has a short lifespan, the plant blooms consistently, ensuring a prolonged display. This species is well-suited for wildflower meadows or gardens designed to attract wildlife.
