Girardinia diversifolia, commonly known as the Nilgiri Nettle , Himalayan Giant Nettle or Nepalese Allo, is found abundantly in open forest land and river side of moist habitat in Nepal and in Himalayan parts of India like Uttarakhand, Himachal Pradesh and J&K. It grows naturally within elevations of 1,200 to 3,000 metres (3,900 to 9,800 feet). It is a shade bearing, tall, stout and erect herb growing up to 3m height with perennial roots stock. The plant is found on clump and each clump has many stem. The stem bark contains fibers of unique quality which is strong, smooth and light.
Allo is a 1.5 to 3 metre tall perennial herbaceous shrub that grows without cultivation all over Nepal. It most frequently occurs in the hilly and mountainous regions at altitudes up to 3000 m.
Traditional users of Allo are ethnic groups from across Nepal, including the Gurung, Magar, Rai and Tamang people. Allo products are culturally important to both the Gurung and the Rai. It is also sold for commercial and non-religious purposes. Non-fibre uses of the plant range from fodder and fuel wood, to use as a live fence and in traditional medicines. Allo fibre is very flexible and has high tenacity, allowing it to be used in a multitude of applications ranging from clothing and bags to floor mats and rope. Fibres made from allo are fully biodegradable.
