It is native to Europe, western Asia, northern Africa, and western North America.[1][4] Like some other species in the family Blechnaceae, it has two types of leaves.

The species was first described in 1753 by Carl Linnaeus as Osmunda spicant. It has been placed in a wide range of genera, including Blechnum (as Blechnum spicant).[1] In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the genus Struthiopteris, in the subfamily Blechnoideae.[9]
