A tropical fern prized for its leathery, deeply divided dark green fronds that are more durable than most ferns. Best grown indoors or in warm, humid environments with indirect light and consistent moisture.
Why grow it
Leather leaf fern's primary advantage over softer-fronded species is its exceptional durability and longevity once established in suitable conditions. The fronds resist tearing and decay better than most fern species, making it a reliable choice for intermediate indoor gardeners who want fern foliage without the fragility typical of the family. It tolerates slightly drier air than many tropical ferns, though it still requires consistent moisture and humidity to thrive.
Watch out for
This fern can take several months to acclimate to indoor conditions before showing vigorous growth, so early stagnation should not be mistaken for failure. Scale insects and spider mites are common indoor pests that target this species, so regular inspection of frond undersides helps catch infestations early. Overwatering or allowing soil to remain waterlogged will encourage root rot faster than underwatering, requiring careful attention to drainage.
