Oriental Poppy highlights the garden from spring to early summer. These eye-catching perennials have huge, silky-satin flowers and, when planted in small groups, their bold blossoms give a colorful punch to borders. Growing in clumps 3' tall and wide, the flowers are generally 4-6" wide with purple-black centers atop stems clad with thistle-like, silvery-green leaves. Incredibly showy, the flowers last about 10 days. The attractive seedpods that follow the fading flowers keep the display going for weeks. Poppies can be used in dried flower arrangements or left in the garden for the visual interest they bring.
