Osmundastrum cinnamomeum
Alternative names: Cinnamon Osmunda
French: Osmonde cannelle

Cinnamon Fern is a large, native deciduous fern known for its graceful, arching green fronds and the tall, upright cinnamon-coloured fertile fronds that appear in early summer. Its name comes from the rich cinnamon-brown colour of its spore-bearing structures, which rise like candles from the center of the plant.

The plant also produces fuzzy, felt-covered fiddleheads, which are not edible, but add visual interest in early spring. Over time, this fern forms large, dramatic clumps that are perfect for moist woodland gardens, streambanks, or rain gardens.

Cinnamon Fern prefers partial to full shade and consistently moist soils. It does not tolerate drying out and should be mulched and watered regularly, especially during hot spells. It thrives in rich, organic soil with good drainage.
