Commonly known as the pink maidenhair
fern, ruby maidenhair fern or rough-leaved maidenhair fern, it is a
small, evergreen fern of the Pteridaceae family. It is particularly
notable because its new fronds emerge with a highly decorative pink,
reddish or bronze hue before maturing into a glossy dark green. It is
native to the tropical and subtropical regions of Africa, Asia,
Australia and New Zealand, and is highly prized in indoor gardening for
its elegant, feathery foliage and slender, dark stems. The term
‘hispidulum’ comes from Latin and means ‘finely hairy’, referring to the
minute hairs on its rachises and petioles. Although ferns of the
genus Adiantum are reputed to be fussy, this species is slightly more
drought-tolerant than other traditional maiden ferns if established
correctly. It requires bright indirect light or partial shade. Direct
sunlight will easily scorch its leaves. A spot near north- or
east-facing windows is ideal. Keep the potting mix consistently
moist, but avoid waterlogging, which causes the roots to rot. It is best
to water it by capillary action (from below) using lukewarm, lime-free
water. Reduce the frequency slightly in winter. It requires high
humidity. Place it in naturally humid rooms such as the bathroom or
kitchen, group it with other plants, or use a humidifier. Avoid draughts
and direct heating at all costs.
