Dryopteris affinis 'Cristata The King' (scaly male fern 'Cristata') is a member of the Dryopteridaceae family. This fern exhibits a bushy growth habit and is characterized by its semi evergreen foliage. It has a hardiness rating of hardy – cold winter (-15 to -10ºc) and is hardy through most of the UK even in severe winters. May not withstand open or exposed sites or central / northerly locations. Many evergreens suffer foliage damage and plants in pots will be at increased risk.
When fully mature, Dryopteris affinis 'Cristata The King' can reach an ultimate height of 1–1.5 metres and a spread of 1–1.5 metres. For optimal growth, it prefers a south–facing, west–facing, north–facing, or east–facing aspect and an exposed or sheltered position. It thrives best in chalk, clay, loam, or sand soil types and should be placed in full shade, full sun, or partial shade.
