Cyrtomium fortunei (Fortune's cyrtomium) is a member of the Dryopteridaceae family. This fern exhibits a bushy growth habit and is characterized by its evergreen foliage. It has a hardiness rating of half-hardy – unheated glasshouse/mild winter (-5 to 1ºc) and is hardy in coastal / mild areas except in hard winters and at risk from sudden (early) frosts. May be hardy elsewhere with wall shelter or good microclimate. Can survive with artificial winter protection.
When fully mature, Cyrtomium fortunei can reach an ultimate height of 1–1.5 metres and a spread of 0.5–1 metres. For optimal growth, it prefers south–facing or west–facing or east–facing aspect and sheltered positions. It thrives best in chalk or clay or loam or sand soil types and should be placed in full shade or partial shade.
