Maidenhair Fern vs Peacock Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Maidenhair Fern
Adiantum spp.
Maidenhair ferns are delicate and graceful ferns known for their lacy, fan-shaped fronds and wiry, black stems. They are primarily outdoor plants in their natural habitat, thriving in moist, shaded environments like stream banks and rocky cliffs. People are drawn to their elegant appearance, making them popular as houseplants despite their demanding care requirements. They typically grow to a height and spread of about 1-2 feet, forming a dense, arching clump of foliage. Their delicate appearance belies their resilience in the right conditions.
Peacock Fern
Selaginella willdenowii
Selaginella willdenowii, commonly known as Peacock Fern, is a fern ally prized for its iridescent blue-green foliage. This plant is not a true fern but a spikemoss. The shimmering effect is caused by structural coloration, where light reflects off the leaf surface. It thrives in humid, shaded environments, mimicking its native rainforest habitat. While it can be grown indoors, maintaining the necessary humidity is crucial for its survival. People grow it for its unique and captivating foliage, adding a touch of exotic beauty to indoor spaces or terrariums. It is primarily an outdoor plant in tropical climates.
