Asplenium nidus Birds's Nest Fern1

Edward F. Gilman2

Introduction

Eventually reaching about four feet tall and wide, Bird's Nest Fern is a striking plant to use as a specimen planting, at entranceways, or in containers where it will always attract attention (Fig. 1). The large, stemless, apple green leaves have a black, prominent midrib and unfurl from a tight center, giving a bird nest effect. The spores are borne in prominent brown sporophores on the underside of leaves.

Use and Management

Growing in rich, moist soil, Bird's Nest Fern prefers shady locations. Leaves turn yellow and the plant stops growing in the sun. Like many ferns, drought tolerance is minimal. It can also be copper-wired to tree trunks to grow on a fibrous slab. Plant on two to three-foot centers to create a mass planting.

There is a dwarf cultivar which grows to about two feet tall and wide. It's reportedly cold hardy into the lower part of USDA hardiness zone 8b.

Propagation is by spores or from tissue culture.

Problems include foliar nematodes, scale, slugs, and snails.

Pest and Diseases

No diseases are of major concern.
