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]
