About Maidenhair fern
Adiantum pentadactylon, commonly known as Avencão, is a delicate and elegant fern native to South America. Its finely divided, bright green fronds with a velvety texture give it an ethereal appearance, making it ideal for terrariums, hanging baskets, or as an indoor plant in humid and shady environments.
Native range
Tropical America, from Mexico to Brazil and the Caribbean
Care tips
It requires bright, indirect light or partial shade; direct sunlight will scorch its delicate fronds. Keep the substrate consistently moist but avoid waterlogging, as it is prone to root rot; good drainage is crucial. It thrives in high ambient humidity, so regular misting or a nearby humidifier is beneficial. A common mistake is allowing the substrate to dry out completely between waterings, which leads to irreversible wilting of its fronds.
