Our favourite fern, the Maidenhair Fern or Adiantum is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet.
When growing maidenhair fern indoors, the plant prefers small containers and dislikes repotting. Maidenhair is also intolerant of low humidity or dry air from heating or cooling vents when grown in the home. Therefore, you will either need to mist the plant daily or set it on a water-filled pebble tray. Maidenhair ferns are one of the few plants that you cannot over-water! They love to be consistently moist at all times. The easiest way to achieve this is to keep a deep tray under the pot they are in.
From temperature, to water, to sunlight, maidenhair ferns are divas in every way. Direct sun will lead to scorching, but too little light will cause poor growth and yellowing fronds. If possible, place in a location that gets indirect morning or afternoon sun with no drafts. A temperature of about 21°C is ideal, but temperatures below 16°C should be avoided.
Maidenhair Ferns, like many other true ferns, are non-toxic to dogs and cats and are air purifying plants.
