Ferns are one of the oldest and most adaptable plant groups on Earth. They bring a natural beauty to both indoor and outdoor spaces with their rather unique fronds and shapes. They do not produce flowers, but they still add charm to the space with their large and divided leaves.
There are more than 10,000 species of ferns, which vary significantly in size, shape, and habits. Ferns are also beneficial as houseplants because they improve air quality and increase humidity. Here are some of the most popular types of ferns that are suitable for both indoor and outdoor cultivation.
Ostrich Ferns
The ostrich fern gets its name from its fronds, which resemble the feathery plumes of an ostrich. These deciduous ferns are native to North America and can reach up to 4 to 6 feet tall. They are easy to maintain and are mostly tolerant to diseases.
They can be grown in any soil, and work particularly well in wet gardens and areas prone to erosion. These ferns prefer partial to full shade and thrive in USDA hardiness zones 3 to 7. They are best suited to cooler summer climates and won’t perform very well in southern regions.
Western Maidenhair Fern
Adiantum aleuticum is commonly known as Western maidenhair fern, and it is a deciduous or semi-evergreen perennial fern. This fern has bright green fronds that stand very gracefully. It unfolds and spreads like fingers of a hand, which are supported by slender, shiny, purple-black stems.
This fern enhances the look of shaded garden areas or indoor spaces with its airy foliage and natural charm. It thrives best in medium to bright, indirect light with high humidity. It prefers moist and well-draining soil. Maidenhair fern is native to North America and grows best in USDA hardiness zones 3 to 8 in shade or partial sun.
Lady Ferns
This is a popular choice for outdoor gardens, known for its finely textured fronds. They come in a unique range of colours. The Japanese Painted Fern variety is particularly striking for its dramatically coloured foliage, which often comes in blue-greens and silvers. It also features red or purple central ribs, adding to its visual appeal. It grows best when planted in USDA hardiness zones 4 to 9.
Wood Ferns
It is another popular choice among gardeners who prefer growing ferns outdoors. It is an adaptable plant with upright fronds that look abundant and stately in woodland gardens. The autumn fern is a variety of wood fern that turns copper-red in spring. As the season progresses, it matures to a deep green, making it even more beautiful. These ferns work well in zones 4 to 9.
Boston Fern
This is a classic choice for a houseplant because of its easy care requirements. These plants need bright light but must be protected from direct sunlight that can burn their delicate fronds. Once the right location is found, it is better to keep the fern there, as these tropical plants do not handle change well. It should be kept away from drafts and temperature fluctuations.
The soil should stay moist without drying out too much between watering sessions. If the soil gets too dry, the fronds may turn brown and dry. A pot with good drainage is necessary; otherwise, there is a risk of root rot, which can lead to yellow, soft foliage. Boston ferns do well without heavy fertilization; it is best to keep fertilization minimal. It also loves humidity, so daily misting can keep them healthy.
Lemon Button Fern
This is a compact and resilient fern that is a much smaller version of the Boston Fern. It is native to Asia and can reach up to 12 inches in height. It works well for those just starting out with houseplants as long as the growing conditions are appropriate.
The lemon button fern’s fronds have a delightfully fresh lemon scent, leaving the room smelling wonderful. The plant thrives best in USDA hardiness zones 8 to 10, and prefers partial to full shade.
Cinnamon Fern
The cinnamon fern is scientifically known as Osmunda Cinnamomea. This fern produces cinnamon-brown fronds that bear spores amid soft, blue-green sterile fronds. This gives it a cinnamon-stick appearance, and its vase-like arrangement, coupled with chocolate-brown tips, adds to its visual appeal.
It is native to American and Eastern Asia, and it makes an excellent focal point in garden spaces. It thrives best in moist, shaded areas, reaching 2 to 5 feet in height and spreading 2 to 3 feet. It requires partial sun for healthy growth and USDA hardiness zones 4 to 10.
Brilliance Autumn Fern
This fern has a bold appearance with its coppery red colour, making it rather distinct from other types of ferns. It thrives in a wide range of light conditions, from dappled sunlight to deep shade. As it matures, it develops deeply cut, dark green leaves.
It is easy to grow and adapts well to drier soils in cool or shaded locations. It grows up to 24 inches tall and 18 inches wide, preferring partial to full shade. It is best to plant this fern in USDA hardiness zones 4 to 9.
Staghorn Fern
It is one of the most unusual ferns available. Its deep-green, long, antler-like fronds give this houseplant a dramatic appearance. It can also grow quite large, and since it was used to grow on the sides of the trees, it can absorb moisture through both its fronds and roots. The soil should stay moist but not soggy, and best to grow in a draining pot.
This fern can be mounted on wood or other materials; however, it must be submerged in water for approximately 5 minutes once a week. During the growing season, it should be fertilised weekly. The plant needs bright light but no direct sun, and grows best in USDA hardiness zones 9 to 12.
Bird’s Nest Fern
The bird’s nest fern’s scientific name is Asplenium nidus, and it is an epiphytic species that loves humidity. It can absorb nutrients and moisture directly from the air around it. It is native to Asia, Australia, and Africa, and is ideal as a bathroom plant.
The fronds of the bird’s nest fern are spoon-shaped and grow in an upright position. It can grow up to 5 feet tall and prefers partial to full shade. The ideal USDA hardiness zones for this fern are 11 to 12.
Asparagus Fern
It goes by the scientific name Asparagus densiflorus ‘Myersii’. This tuberous, evergreen perennial can brighten any garden year-round with its ornamental beauty. The plant features upright to arching stems densely covered with soft, deep green foliage resembling a foxtail. Its foliages are well-suited for floral arrangements.
During late spring and early summer, this fern produces small, fragrant white flowers, and by fall, the plant will bear red berries. It is native to eastern and South Africa, but has now become popular and invasive in regions like Australia, Florida, Hawaii, and southern California.
The Myersii cultivar is more compact and produces fewer berries, and is not as invasive as other varieties. This cultivar is one of the most preferred varieties due to its ornamental value. The plant grows best in partial sun and reaches a height of 1 to 2 feet with a spread of 3 to 4 feet. It is ideal to plant them in USDA hardiness zones 9 to 11.
Kimberly Queen Fern
The Kimberly Queen Fern is a graceful tropical plant that is popular among gardeners. It has large, upright fronds that are covered in dense, sword-shaped leaves. It is easy to maintain and significantly less messy than the equally popular Boston fern, as it rarely sheds its leaflets.
This fern grows up to 3 feet in height and thrives best in USDA hardiness zones 9 to 11. When it comes to sun exposure, it prefers partial to full shade.
New York Fern
New York fern is a delicate, deciduous type of fern that is also known for its finely textured fronds. These fronds measure between 8 and 25 inches in length and have a distinct elliptical shape. The plant grows in clumps from dark brown soil and spreads rapidly to form dense, lush colonies.
It is native to eastern North America, and works well for planting along streams or ponds with shade or lightly filtered sunlight. It is especially useful to fill the gaps left behind by spring ephemerals in woodland gardens.
This fern does best when grown in USDA hardiness zones 3 to 8, with sun exposure ranging from partial sun to complete shade. It can reach a height of 8 to 2 inches and spread 1 to 3 feet.
Button Fern
The button fern is a charming little evergreen plant with a unique look to it. It has deep green leaves that look like small buttons. It is ideal for small spaces like gardens, patios, or windowsills because of its compact growth.
This plant is native to Australia, and can thrive best in USDA hardiness zones 9 to 11. Since the fern is quite small, it can only reach up to 1 foot in height. It prefers part shade conditions for healthy growth.
Conclusion
These are some of the ferns available, and choosing the right fern depends on several factors. They can add charm to both outdoor and indoor spaces with their natural, lush appearance. Their ease of maintenance makes them a perfect choice of plant for even beginners who have just started gardening.
