Cinnamon Fern

Osmundastrum cinnamomeum
Español: Adelfa
Called cinnamon fern because of the color of its fertile fronds. In Florida it sends up its fertile fronds in the spring and fall; farther north in its large range, the fertile fronds only emerge in the spring.



Useful as a specimen in moist areas and in rain gardens or bioswales. Its urn shape and orange spore producing fertile leaves make this fern attractive as an individual specimen in areas that have adequate moisture. Large size and grace are its principal appeal. Evergreen in south-central FL. Deciduous in north FL.

Tolerance

Not salt tolerant of inundation by salty or brackish water.



Low/no tolerance of salty wind or direct salt spray

Habitat

This species typically grows on seepage edges of swamps and in the upper reaches of baygalls (bay swamps). It is not found in long-term standing water though it grows well on rotten logs and hummocks in swamps. It is an indicator of seepage conditions.
