In Australia, A. australis is commonly grown and is a robust species, capable of tolerating some sun if kept in moist soil.[12] A. dregei is a popular garden plant in South Africa, with plants being collected for use from the wild sufficiently often to cause it to become extinct in some areas.[13]

Culture

The silver fern, Alsophila dealbata has become a widely recognised symbol of New Zealand, although it is not an official national symbol.[14]

In the 1971 comedy film A New Leaf, Henrietta Lowell (played by Elaine May) is a botanist whose dream is to classify a new species of fern. On a honeymoon trip, she indeed discovers a new species which she names Alsophila grahami after her new husband Henry Graham (Walter Matthau). She describes the plant as having a vestigial indusium.
