Do you long for a lush green ambiance? Then, growing ferns would have crossed your mind. After all, ferns are one of a kind. They beautify the place they reside and fill it with a peaceful vibe.
Ferns are one of the oldest plants, residing on Earth for 360 million years. The fossils that existed even before dinosaurs depict the historical presence of ferns. Moreover, the sweet touch of tropical rainforests they carry makes them a must-have on the gardening list.
The best part is ferns are easy to grow both indoors and outdoors. The reason is their highly resistant nature towards diseases and pests and adjusts to indoor and outdoor conditions.
Besides unfurling dark green foliage, ferns come in different shapes, sizes, and appearances. Hence, let us discuss the different types of indoor and outdoor ferns to grow (with pictures), so you can give a new kickstart to your gardening skills.
What are Ferns?
Ferns are a special group of plants with dark green foliage. They do not produce flowers and seeds and form the perfect fit for an entirely green garden. They belong to the family of Pteridophytes and fall into the category of perennial plants.
You might wonder how ferns reproduce if not with flowers or seeds. Well, ferns have a unique way of propagation through spores. The spores reside on the undersides of their fronds, which is another name for the fern leaves.
Types of Indoor Ferns
Ferns are popular indoor plants that fill the ambiance with dark green foliage. They go well on your desk or sofa table and provide a peaceful environment. They can grow well even indoors, as they need little maintenance.
However, you are only good to go with planting ferns indoors if you can provide them with the outdoor environment they prefer. Most indoor ferns prefer a shady area with regular misting. Here are some indoor ferns you can bring home.
1. Bird’s Nest Fern (Asplenium Nidus)
Bird’s nest fern is one of the most common ferns grown indoors due to their varying kinds of fronds under different shade conditions.

Button fern is an indoor fern that requires the least maintenance. It has no specific growing conditions and can thrive indoors without requiring moisture or humidity.

The closest a fern can get to moss would be the Rabbit’s Foot. Its name comes from the shape of the fronds, tiny and triangular, like a rabbit’s.
