Types of Ferns To Grow Indoors

Many ferns and fern-like plants make wonderful houseplants to grow inside your home. There are so many types of ferns, you might be unsure where to begin when deciding which to grow.

Ferns Unveiled: A Variety Showcase

Foxtail Fern/ Asparagus Fern

Foxtail Fern

Also known as asparagus fern, the foxtail fern is a southern African native often grown as a houseplant in temperate climes. 

Though not a true fern, this plant’s fern-like foliage means that it is often mistaken for one, and has taken on its common name. It is closely related to the vegetable asparagus but is toxic to people and pets, so care should be taken if growing it inside your home.

  • Sun Exposure: Partial sun
  • Soil Type: Well-drained, acidic, or neutral
  • Hardiness Zones: 9a-11a
  • Native Area: Southern Africa

Boston Fern

Boston Fern

Boston fern is, perhaps, one of the most popular ferns to grow indoors. It is certainly a common choice – and with good reason. This is one of the easiest ferns to grow and is a little more tolerant of under-watering than most other ferns that are commonly grown indoors. 

You can grow Boston ferns in any pot, or hanging container, in bright, indirect light, though it will do best in a humid room – like a light bathroom for example.

Lemon Button Fern

Lemon Button Fern

This is a dwarf cultivar, a relative of the ubiquitous and ever-popular Boston fern, perfect for new houseplant parents and those without a huge amount of space for an indoor garden. 

This fern is known for being not only compact but also resilient – less fussy than many other houseplant ferns. It also has fragrant foliage that smells lightly of lemon in the spring and summer months.

  • Family: Nephrolepidaceae

Macho Fern

Macho Fern

A larger relative of both of the above, the macho fern, or giant sword fern is a tropical fern that is popular as a houseplant for its dramatic, large, and impressive foliage. 

This fern is a great choice if you have the space for a larger specimen inside your home.

Kimberley Fern

These epiphytic plants are a little more challenging to grow than many other ferns. But they are increasingly popular with those looking to branch out and give something new a try.

Bird’s Nest Fern

Bird’s Nest Fern

The bird’s nest fern is a popular fern to grow indoors. It has large, banana-like fronds with a crinkled appearance. As the plant matures, fronds naturally curl and turn brown, and the plants’ old leaves look like giant nests up in the branches of the trees on which these epiphytes grow.
