Quick facts

About Asplenium aran-tohanum

Asplenium aran-tohanum, known as Doradille d’Aran et Toha, is a small, delicate fern endemic to specific mountain ranges. Its fronds are finely divided, bright green, forming a compact rosette. It is ideal for closed terrariums, shady rock gardens, or as an indoor plant in a cool, humid environment.

Native range

Aran Valley (Spain) and Toha Valley (France), in the central Pyrenees.

Care tips

It requires bright indirect light or partial shade; direct sunlight will scorch its fronds. Keep the substrate consistently moist but not waterlogged, preferably with rainwater or demineralized water. Use a well-draining, organic-rich substrate, such as an orchid or fern mix. Avoid dry environments and drafts, which can lead to rapid dehydration of this sensitive species.
