Asplenium nidus is an epiphytic fern that normally grows in the wild attached to trees.
They have long, leathery, shiny, apple-green fronds with prominent black midribs. They grow in a dramatic funnel shape, resembling a birds nest, hence the name.
This species requires a warm, moist, microclimate and dappled light for optimum growth. They can take a little direct sun but no more than an hour or so of morning sunlight otherwise the fronds will scorch and die back.
They go well in shady East Coast gardens, greenhouses and conservatories especially alongside orchids and bromeliads.
