Celandine Poppy - Stylophorum diphyllum

The Celandine Poppy is native to moist woodlands and streambanks of the southern United States including Michigan. However, it is fully hardy here in Wisconsin. It is affected by invasive garlic mustard and is considered threated in many areas.

The Celandine Poppy grows 1 -1 1⁄2 feet tall and spreads up to a foot across. The 1-2" buttercup-like flowers are bright yellow to yellow-orange in color. They have four petal-like sepals with numerous stamens in the center that surround a yellow-green pistil with a knobby stigma.

The Celandine Poppy blooms early spring and continues into the summer.

Other names: Wood Poppy, Woods-poppy.

The Celandine Poppy looks similar to Greater Celandine that is considered an invasive plant. However, the yellow flowers of the Celandine Poppy are larger that those of Greater Celandine. Also, the flowers of the Celadine Poppy usually overlap; whereas, the flowers of Greater Celandine have petals that are long and narrow and often have space between them. The seedpods of the two plants are also distinctly different. The Celandine Poppy have rounded, dangling seed pods covered in bristles. Greater Celandine have long, narrow seedpods that are upright.
