AGM Deciduous and very hardy fern from North East America with a potential height to 150cm (5 feet)
It prefers moist to wet organic rich soils. In drier soils it will not grow so large but still be an impressive plant when mature. It has a lovely shuttlecock form when mature with large cinnamon brown 'flower' spikes, as seen in the picture of a mature fern.
Recently assigned to a separate genus, Osmundastrum, O. cinnamomea is the only representative in this genus. This fern can be regarded as a living fossil, it has been around for at least 75,000,000 years, maybe longer.
