Plume Poppy is a vigorous rhizomatous perennial that commands attention in the summer garden with its tall, architectural presence and delicate flower displays.

The plant's large, scalloped leaves with heart-shaped bases create a dramatic backdrop, displaying light green to olive tones on top and silvery gray beneath. Its spreading, spreading habit and low maintenance requirements make it a bold statement plant for gardeners willing to manage its enthusiastic growth.
