What Is Cinnamon Fern?
The Cinnamon fern is considered one of the most ancient plants.
It is native to tropical regions, like Eastern Asia, South America, and the Eastern United States.
Cinnamon ferns thrive best in wet areas like bogs, swamps, or woodland gardens.
Cinnamon ferns belong to the family Osmundaceae and are botanically known as Osmundastrum cinnamomeum.
These plants are mainly outdoor ones, and people plant them in the garden.
According to the study, these ferns are living fossils as they have been living for more than 75 million years .
Types of Fronds
Cinnamon ferns have two different types of leaves, which are also called fronds.
Fertile fronds grow from the center of this plant.
These leaves have an attractive cinnamon color, which is the main reason for getting the name “Cinnamon.”
This foliage is erected and bears spores.
They lose their greenish colors when the season progresses.
The stems stand upright till the sterile leaves die due to the frost.
Sterile fronds surround the fertile ones.
They are more compound, greenish, and larger than fertile fronds, and can be 5 feet long.
They arise from the base of the Cinnamon ferns and slowly unfold themselves.
These bright green leaves look fascinating throughout the entire summer but turn yellow during the autumn.
