For those with less brightly lit rooms but yearn for indoor plants, consider ferns as a possible solution. Bird's Nest Ferns are unique, with broad, strap-like leaves that look nothing like fern fronds, and can slowly grow to two feet in length after many years. Pair this bright, apple-green fern with maidenhair ferns or other house-happy ferns in an indoor container, making it an intriguing combination of colors and textures. Most ferns enjoy higher humidity than humans, so keep them away from heater vents and mist often. For those with pets, ferns are a pet-friendly choice for houseplants.
