Adiantum venustum aka Himalayan Maidenhair

Adiantum venustum, also known as the evergreen maidenhair or Himalayan maidenhair, is a species of fern native to China and the Himalayas. This slow-growing plant thrives in moist rocks and soil enriched with humus and dead leaves. It is highly resilient, remaining largely evergreen even in temperatures as low as -10°C, although it becomes deciduous under harsher conditions. In India, it is referred to as black Hansraj due to its black stalks. With a height ranging from 15 to 25 cm and a width of up to 0.9 meters, this fern forms a spreading mat through its rhizomatous roots. Its fronds are soft green and triangular, consisting of multiple fan-shaped segments attached to black stems. In mild areas, it retains its foliage throughout the year, while in autumn and winter, the fronds often take on an appealing rusty-brown hue.
