Adiantum raddianum

Adiantum raddianum, the Delta maidenhair fern, is one of the most popular ferns to grow indoors.[2] Its common name comes from its shiny, dark leafstalks that resemble human hair. The triangular fronds are semi-erect in the beginning then droop gracefully as they age and can be up to 12 inches (30 cm)[3] long by 6 inches (15 cm) wide.

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.[4] It requires high humidity, well-drained soil, bright indirect light, and a fairly constant temperature.[2] The cultivars ‘Brilliantelse’ and ‘Kensington Gem’ have won the Royal Horticultural Society's Award of Garden Merit.[4][5]
