Adiantum raddianum, the Delta maidenhair fern, is one of the most popular ferns to grow indoors.[3] It is native to South America and its common name comes from its shiny, dark leafstalks that resemble human hair.[4] It typically grows about 17–19 in (43–48 cm) tall and up to 22 in (56 cm) wide.[5] In the wild, it is found on forest floors, rock crevices, river banks, coastal cliffs, and basalt banks along trails and streams.[6] The triangular fronds are semi-erect in the beginning then droop gracefully as they age and can be up to 12 inches (30 cm)[7] long by 6 inches (15 cm) wide. The genus name Adiantum comes from the Greek word "adiantos", meaning "unwetted" (in reference to the leaves).[5]
This plant is hardy down to 5 °C (41 °F), so must be grown indoors in temperate regions. However it may be placed outside in a sheltered spot during the summer months.[8] It requires high humidity, well-drained soil, bright indirect light, and a fairly constant temperature.[3] It prefers neutral or slightly alkaline soil and is suitable for USDA hardiness zones 10 and 11.[9] It can be susceptible to scale and mealybug.[4] The cultivars ‘Brilliantelse’ and ‘Kensington Gem’ have won the Royal Horticultural Society's Award of Garden Merit.[8][10]
A. raddianum is sometimes considered invasive in Hawaii and French Polynesia.[6]
