Cinnamon fern grows in arching, vase-shaped clumps with dramatic effect in the landscape. Contrasting fertile and non-fertile fronds create an interesting foliar display. It supports larval forms of several pollinator species, rather than serving as a direct source of nectar or pollen for adult pollinators.
