About Adiantum macrophyllum
Adiantum macrophyllum, commonly known as Largeleaf Maidenhair Fern, is an elegant and delicate fern featuring pinkish or reddish fronds when young, maturing to a deep green. Its large, pinnate leaflets give it a unique texture and lush appearance. It is ideal for terrariums, humid shaded gardens, or as an indoor plant in a high-humidity environment.
Native range
Tropical America, from southern Mexico to Brazil and Bolivia
Care tips
It requires bright, indirect light or partial shade; avoid direct sunlight which can scorch its delicate fronds. Keep the substrate consistently moist, but never waterlogged; water with distilled or rainwater if possible. It needs high ambient humidity, so it benefits from regular misting or a humidifier. A common mistake is allowing the substrate to dry out completely, which can be fatal for this fern.
