cinnamon fern​



Osmunda japonica

Osmunda regalis

The Cinnamon fern is native to both Virginia and Missouri.

Cinnamon ferns reproduce using spores.

They are called cinnamon ferns because they produce large brown fronds that look like cinnamon.

Cinnamon ferns like to grow near water. In mid to late spring, one or more spike-like fertile leaves, nearly as tall as the sterile leaves, grow in the center of the leaf clump. Animals eat it to help with stomach aces. 

Cinnamon Ferns were used by Native Americans as a common food source. They would harvest the fern croziers,  which were less than 8 inches long, and boil them. The cinnamon fern's main modern uses are all medicinal. A decoction of the roots can help internal issues, such as headaches, joint pain, etc.


Unlike most ferns, the cinnamon fern grows only on the east coast, in very wet, shady environments. They also are a good food source and help with stomach problems. Animals will eat the fronds off the cinnamon ferns.

Cinnamon fern is a rather common plant.
