Athyrium niponicum, commonly known as Oriental ladyfern[1] and Japanese painted fern[2] is a species of fern native to eastern Asia.[3]

This species was redefined as a member of genus Anisocampium in 2011 based on phylogenetic analyses.[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".[3]

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.[5] 'Pictum' is also considered to be a cultivar; varieties and cultivars are bred to achieve midribs in many shades of red.[6]

A. niponicum var. pictum has gained the Royal Horticultural Society’s Award of Garden Merit.[7] as has the cultivar ‘Silver Falls’.[8]
