Asplenium nidus (bird's nest fern)
Bird's nest fern — evergreen epiphyte from the tropics of Asia and Oceania. Does not flower, reproduces by spores; accumulates organic matter in the centre of the rosette and creates its own soil.
Origin and family
Asplenium nidus (bird's nest fern) belongs to the spleenwort family (Aspleniaceae). In the wild it is found in the tropics of Southeast Asia, Oceania and Pacific islands. It is an epiphytic fern: it grows on tree trunks and branches, not parasitizing them but using them as support.
No flowers or seeds
Like all ferns, Asplenium nidus does not flower. Reproduction is by spores, which mature on the underside of the fronds. The plant existed in this way even before flowering plants appeared — an ancient and successful strategy.
The "nest" and self-feeding
In the centre of the leaf rosette, fallen leaves, dust and organic matter accumulate. The fern literally creates its own soil — in the wild this allows it to obtain nutrients high up on the tree.
Who lives in the nest
In the wild the "nest" of Asplenium often hosts insects, small frogs and lizards. The plant becomes a mini-ecosystem and shelter.
Benefits indoors
Asplenium is considered one of the plants that improve indoor air quality (filtering some harmful substances). It is undemanding and does well in warm, humid conditions.
Quick Answer
Asplenium nidus is an evergreen epiphytic fern from the tropics of Asia and Oceania; reproduces by spores, creates its own soil in the rosette centre, in the wild provides shelter for small animals and improves air quality.
