Maidenhair Fern
Adiantum raddianum
📖 About this plant
One of the most delicate and graceful ferns, featuring fan-shaped leaflets on wiry, dark, glossy black stems that resemble hair. The soft, light green fronds create a cloud-like effect that is both elegant and ethereal. While beautiful, it is notoriously fussy about humidity — crisp, brown fronds are a sign the air is too dry. Requires consistent moisture, high humidity, and protection from drafts and direct sun. Best grown in bathrooms or with a humidity tray.
