Description

A deciduous, clump-forming, perennial fern native to the Tropical Americas and West Indies.  Genus name comes from the Greek word adiantos meaning unwetted in reference to the water repellent foliage.  Specific epithet references Italian botanist Giuseppe Raddi.

Partial shade to shade, but loses vitality in too much shade.  Needs moist to wet soil and should not be allowed to dry out.  Spreads by rhizomes.  Needs humidity and, if grown as a houseplant, does well if kept in bathrooms.

Rhizome short, widely creeping.
