A tropical plant, the bird's nest fern (Asplenium nidus) grows well as a houseplant. The plant's growth pattern forms a funnel shape that resembles a bird's nest. The fronds often reach up to 5 feet in length. The reproductive spores appear on the undersides of the leaves. In U.S. Department of Agriculture zones 9 to 11, the fern can survive outside as a garden ornamental but in colder regions it must be kept indoors.
