Pronounced ADD-ee-an-toom and commonly called maidenhair fern
The most delicate of ferns, with dainty, fan-like, pale green triangular leaves on black wiry stalks
Tropical and subtropical areas of Australia, New Zealand and the Americas
Most common ones available are raddianum, monocolor, fragrans, scuteum roseum. Adiantum brilliantese (pictured here) has tiny leaves which start out gold, slowly turning to pale green, but often retaining a golden edge.
Not difficult to grow but make sure it does not dry out. It needs a steady humid atmosphere with no direct sunlight, and does well in bathrooms and the shaded parts of a conservatory or greenhouse. Keep the roots moist, but not wet, and spray often, daily if in a heated room. It prefers indirect light.
