Ferns are proven to be one of the oldest existence around for over 350 million years. This family of ferns do not produce flowers or seeds, but reproduce through spores and are prized for their fronds, which delicately unfurl to reveal unusual and attractive plants.
There is a vast variety of ferns that have different characteristics and are usually tropical evergreen plants, which can be grown in shaded areas.
They can thrive well in low light indoor conditions, bringing much-needed greenery to the dull corners of your house and garden even in winters.
Most garden ferns can be grown both indoor and outdoor when provided the right care. Still, there are certain varieties that do better as a houseplant than when grown in the yard, and vice versa.
There are 3 categories of ferns, with a complete guide about each fern explained below.
- Indoor Ferns
- Outdoor Ferns
- Aquatic Ferns
