Osmundaceae

Botanical Name

OSMUNDA cinnamomea

Plant Common Name

Cinnamon Fern

General Description

This imposing, clump forming, deciduous fern is native to North America, the West Indies, and eastern Asia. Its silver-haired fiddleheads emerge from thick rhizomes in mid-spring, unfurling to large triangular pinnate fronds. Hummingbirds visit the hairy stems to collect down for their nests. Leafless fertile fronds resembling fuzzy cinnamon sticks arise in late spring, collapsing in summer after shedding their spores.

Cinnamon fern thrives in damp humus-rich acidic soil in partial shade. Plant it in moist shady areas of the garden, or naturalize it in damp woodland.
