Pleated Bird's Nest Fern is an unusual specimen with wide, wavy, solid leaves that arch upwards in a fountain shape. New growth emerges from the center, or "bird's nest," and slowly unfurl. They thrive in more humid environments and can handle lower light, so bathrooms may be the ideal home for them. Try not to water the center of the plant, as water tends to pool in the "nest," possibly causing the fern to rot. Bird's Nest Ferns are efficient air purifiers and are non-toxic to pets and humans alike.
