Adiantum venustum
species of plant
Adiantum venustum, the evergreen maidenhair or Himalayan maidenhair, is a species of fern in the genus Adiantum of the family Pteridaceae, native to China and the Himalayas. It is a slow to establish plant that usually grows on moist rocks and soil with a good amount of humus and dead leaves. It is very hardy, largely evergreen to −10 °C, when it becomes deciduous. It is also known as black Hansraj in India for its black stalks at the fronds.
It typically grows to 15–25 cm tall and up to 0.9 meters wide. The soft green fronds are triangular, with numerous fan-shaped segments on each frond, with black stems. The roots are rhizomatous. The whole plant forms a slowly spreading mat.
Cultivation
This plant is cultivated as an ornamental subject in temperate regions, and has gained the Royal Horticultural Society's Award of Garden Merit. It is extremely hardy, down to at least −20 °C (−4 °F), but requires reliably moist conditions in full or partial shade.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Adiantum venustum”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q2824388. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
