In its natural habitat, it grows as an epiphyte (a plant that grows on trees) in the warm, moist, tropical rain forests. Despite its tropical beginnings, it adapts well to being a house plant. Place your potted fern where it is out of direct sun and away from drafts, which can scorch the fronds. Provide humidity and you'll keep it healthy.
Now I spend most of my time in Thailand I get to find all sorts of great indoor plants growing in the wild and within gardens. This A.nidus is growing in my neighbors garden attached to the tree in the picture (right of page).
Bird's nest ferns ( Asplenium nidus , Asplenium antiquum ) are a fern with fronds that grow up to 2 meters (6.6 ft) in length. If you have good space, the bird's nest fern can make a wonderful indoor plant in a large container. During the warmer months, it can be taken out to the courtyard or patio to cheer up the entertaining space. It has few needs, which are easily met.
