Adiantum is made up of elegant evergreen or deciduous ferns in 200 to 250 species from tropical and subtropical areas of North and South America and a few from the temperate regions of Europe, Asia, Australia, New Zealand, and North America. They have distinct glossy black to purple-red stalks. Fiddleheads and young fronds of many species display a purplish-pink color. Grow in a woodland or shade garden.
Noteworthy CharacteristicsGraceful, delicate-looking foliage.
CareOutdoors, grow hardy species in moist, well-drained, moderately fertile soil in an open site in partial shade. Tender species need humusy soil in a partially shaded, open site. Indoors, grow in bright indirect light in summer with plenty of humidity and good ventilation. Water sparingly in winter.
PropagationDivide rhizomes in early spring. Or sow spores as soon as they ripen at 59°F or higher (for hardy ferns) and 70°F (for tender species).
ProblemsRarely, scale insects are troublesome when grown in a greenhouse.
