Wood Poppy (Stylophorum diphyllum)

Wood Poppies And Rain Drops

Wood Poppy (Stylophorum diphyllum)

One of the native plants that bloom in early spring. Native to eastern North America from southwestern Ontario and Pennsylvania, down to Georgia and Alabama, out to Michigan and Missouri.

There are two common names for this plant, Celandine Poppy, and Wood Poppy. There is another Celandine (similar in appearance) that I know of as a highly invasive, non-native plant, Greater Celandine (Chelidonium majus). Since I don’t want that plant with the bad reputation getting confused with the native, I choose to use the common name of Wood Poppy.

Wood Poppy is one of those interesting plants that relies on ants to distribute their seeds in a mutualistic partnership called myrmecochory.

Nature always manages to amaze me.

Farmer Ants

May 20, 2025

These are seed pods and seeds of Wood Poppy. You might be able to see, if you look carefully, that each seed is wrapped with something that looks like a fuzzy white band. This is an elaiosome which is nutrient rich and attracts some ants.

These ants are participating, along with the plant, with seed dispersal in a process called myrmecochory. This is a symboitic relationship in which both the ants and the plants benefit.

The seeds of an amazing number of plants have an attachment called the elaisome which is rich with lipids and proteins. Ants know that their larvae will benefit greatly by being fed these elaisomes, which are brought to them in the nest. After the feeding, the remains of the seeds are placed in the “trash room” of the nest which is a perfect atmosphere for sprouting.

Some of the spring ephemerals that participate in myrmecochory are Trilliums, Bloodroot, Wild Ginger, and Dutchman’s Breeches, Trout Lily, Twin Leaf, Spring Beauty, and Wood Poppy.

Rich Yellow Blooms

April 13, 2025

Wood Poppy (Stylophorum diphyllum) in bloom right now. A marvelous plant native to the east and central United States and southwestern Ontario. Its rich yellow is a color that I adore.

Stylophorum diphyllum has two common names, Wood Poppy and Celadine Poppy. I choose to use the name Wood Poppy since there is another plant with a similar name, Greater Celadine (Chelidonium majus). Greater Celadine has a similar appearance, and is a non-native highly invasive plant. The name Wood Poppy leaves no confusion.

In the wild it is threatened by two invasives that are a concern to many native plants, Garlic Mustard (Alliaria petiolata), and Japanese Stiltgrass (Microstegium vimineum).

Wood Poppy is a flower which only provides pollen for visitors looking for such things, but no nectar. And it is one of those plants that has seeds with an oily appendage called an elaiosome. Ants gather these seeds to provide their larvae a nutritious food source, the elaiosome. They then discard the seeds in their “trash room” where the seeds may eventually sprout. This fascinating process is called myrmecochory.
