Ferns are one of the oldest types of plants on the planet, and they have evolved into an extremely varied family that is found all over the world. The few things that bind ferns together is that, for the most part, they want moist soil, they thrive in more humid climates, and they don't flower.

If you want a beautiful leafy green plant, and you know you love to water frequently, a fern might be a good choice!
