Athyrium niponicum, the Japanese painted fern,[1] is a species of fern native to eastern Asia.[2]

This species was redefined as a member of genus Anisocampium in 2011 based on phylogenetic analyses,[3] but the genus has since been sunk into Athyrium.[4]

This deciduous fern has a creeping rhizome and a tuft-shape array of fronds. The fronds are variable in length, generally 30 to 75 centimeters long but occasionally over a meter in length. They have alternately arranged, subdivided pinnae. The spore-bearing sori on the undersides of the fertile pinnae are variable in shape, being "oblong, hooked, J-shaped, or horseshoe-shaped".[2]

The Latin specific epithet niponicum means "relating to Japan (Nippon)".[5]

This is a commonly cultivated fern, especially A. niponicum var. pictum. It thrives in many kinds of shady garden conditions and produces thick colonies of gray-green fronds with reddish midribs.[6] 'Pictum' is also considered to be a cultivar; varieties and cultivars are bred to achieve midribs in many shades of red.[7]

A. niponicum var. pictum has gained the Royal Horticultural Society’s Award of Garden Merit.[8] as has the cultivar ‘Silver Falls’.[9]
