Ferns make the perfect houseplant and have been popular for many years. Among the group of large ferns, we are all most familiar with Nephrolepis (the Macho Fern). Ferns are very versatile and promote a healthy micro-climate in our homes by purifying the surrounding air and promoting humidity too. As these houseplant ferns originated in (sub) tropical regions, they do like it to be very humid. This makes them ideal for in the bathroom. As a fern also dislikes direct sunlight, these leafy plants will also thrive in a darkish corner.
