Himalayan Flora: A Guide to Rhododendrons and Beyond
Nepal is home to over 6,000 plant species, many found nowhere else on Earth. From lowland sal forests to high-alpine cushion plants, the Himalayan flora is as dramatic as the mountains themselves.
Nepal's extraordinary range in altitude — from 70m in the Terai to 8,849m on Everest — produces one of the world's most diverse floral gradients.
Overview
The national flower, the red rhododendron (Rhododendron arboreum), blankets hillsides between 1,500m and 3,500m in crimson from February to April, turning the Annapurna foothills and Ghorepani ridge into a famous floral spectacle. Nepal has 32 native rhododendron species, ranging from tree-sized to low alpine shrubs. Above 4,000m, cushion plants, dwarf gentians, and Edelweiss cling to rocky slopes in the alpine zone. The high pastures of Khumbu and the Langtang valley support unique communities of these frost-adapted specialists. The medicinal plant Yarsagumba (Cordyceps sinensis), a fungus that parasitises ghost moth larvae, grows above 3,500m and commands extraordinary prices — up to NPR 1 million per kilogram — making it central to the economy of many mountain communities. Conservation of Nepal's flora is managed through ten national parks and wildlife reserves covering nearly 23% of the country.
