Pmacleaya-cordatalume poppy is a rhizomatous herbaceous perennial native to east China and Japan where it grows in woodland margins, along lake and river edges, and within scrub. Plants have lobed and scalloped heart-shaped leaves that are eight to ten inches wide by six to eight inches long and are light to olive green on the top side and whitish gray on the underside. The creamy white flowers lack petals, and have two sepals, and twenty five to thirty conspicuous stamens that give the flowers a feathery appearance. They are carried in branched panicles up to one foot long from mid- to late summer. The plants are vigorous and spread rapidly by both rhizomes and seed. They are an excellent choice for the back of the border where they add a strong architectural element along with valuable texture and color. Both the flower heads and leaves are valued in flower arrangements.
