The cinnamon fern, Osmunda cinnamomea (syn. Osmundastrum cinnamomeum), forms tight circles of fresh green fronds, which grow into a beautiful upright shuttlecock by midsummer. In the centre of the shuttlecock, tight plumes of cinnamon-brown spore-bearing fronds emerge, resembling flower spikes. It’s perfect for growing in bog garden or the pond edge, where it looks fabulous with other foliage plants such as gunners and rodgersia.
