Asplenium antiquum

Japanese bird's-nest fern

A bird's-nest fern of warm-temperate and subtropical East Asia, forming a rosette of undivided, bright green, arching fronds on tree trunks and damp rocks. It is endangered in the wild in Japan and South Korea but common in the nursery trade. It is hardier than A. nidus and grows well as a houseplant in bright, indirect light.
