About Maidenhair fern
Adiantum cunninghamii, commonly known as Cunningham's Maidenhair Fern, is a delicate and elegant fern native to New Zealand. It is distinguished by its finely divided, bright green fronds that grow on dark, shiny stems, creating a feathery effect. It is ideal for terrariums, hanging baskets, or as an indoor plant in a spot where its graceful foliage can be appreciated up close.
Native range
Australia and New Zealand
Care tips
It requires bright indirect light or partial shade; avoid direct sunlight which can scorch its fronds. Keep the substrate consistently moist, but not waterlogged, and ensure high ambient humidity through regular misting or a humidifier. Use a well-draining, organic-rich potting mix. A common mistake is allowing the soil to dry out completely, which can lead to frond dieback.
