About Maidenhair fern
Adiantum obliquum, or Oblique Maidenhair Fern, is a delicate and elegant fern native to tropical regions of the Americas. It is characterized by its finely divided, bright green fronds with asymmetrical pinnae, which give it its 'oblique' name. It is ideal for terrariums, humid shade gardens, or as an indoor plant in hanging baskets, where its graceful foliage can be fully appreciated.
Native range
Tropical America (from southern Mexico to Brazil and Bolivia), and the Caribbean
Care tips
It requires bright, indirect light, avoiding direct sunlight which can scorch its fronds. Keep the substrate consistently moist but never waterlogged, preferably with distilled or rainwater, and ensure high ambient humidity. Use a well-draining substrate rich in organic matter, such as a fern mix or peat with perlite. A common mistake is allowing the substrate to dry out completely, which can lead to frond desiccation and drop.
