Ask a Nepali hiker what colour spring is, and most will say red. From the mid-hills up to around 3,600 metres, forests of Rhododendron arboreum burst into bloom each year, turning entire ridgelines into bands of crimson, rose and white. It's this scale and intensity — not rarity — that earned Lali Gurans its place as Nepal's national flower.
Why the Rhododendron Became Nepal's National Flower
Legal basis: Constitution of Nepal 2015, Article 9(3), which states that the Rhododendron Arboreum is the national flower. Text on Constitute Project.
The rhododendron is Nepal's national flower, and it stands alongside the cow (national animal) and the Himalayan Monal (national bird) among the country's natural symbols. Rhododendron was a natural choice: it grows across the hills and lower mountains that most Nepalis actually live among, unlike symbols tied only to the high Himalaya.
Where many "national flowers" are chosen for rarity or royal association, Lali Gurans was chosen for the opposite reason — its abundance. It is the plant most Nepalis have grown up walking beneath, picking, and using, which is part of why it still resonates as a shared symbol rather than a distant emblem.

How Elevation Changes the Colour
One of the more striking facts about Nepal's rhododendrons is that colour and form shift with altitude. Lower-elevation forests tend to produce the deepest crimson-red blooms, while trees higher up the slope often shade toward pink, rose and, more rarely, white or pale purple. The bands below are a rough guide, not exact limits.
Bloom colour across elevation bands
This banding is one reason trekking routes that climb steadily — like Ghorepani–Poon Hill in the Annapurna region — are famous for rhododendron viewing: a single day's walk can pass through several colour zones at once.
Species Found in Nepal
Nepal is home to about 31 rhododendron species, spread across temperate and subalpine forest zones. A few of the most recognisable:
| Species | Common colour | Typical elevation |
|---|---|---|
| Rhododendron arboreum | Crimson red to pink, rarely white | ~1,500–3,600 m |
| Rhododendron campanulatum | Purple-red fading to white | ~3,000–4,300 m |
| Rhododendron barbatum | Deep red | ~2,400–3,600 m |
| Rhododendron campylocarpum | Yellow | ~3,300–4,000 m |
| Rhododendron lepidotum | Pink to purple; small shrub | ~1,700–4,200 m (most often 3,000–3,600 m) |
Rhododendron arboreum, the widespread, often crimson species, is specifically the one recognised as the national flower.

✦ Did you know?
- Nepal has about 31 recorded species of rhododendron, according to the Department of Plant Resources.
- Not every species blooms red — some, like Rhododendron campylocarpum, flower bright yellow.
- Gurans juice, made from the crimson petals, is a popular seasonal drink in Himalayan hill villages.
Culture, Uses and Everyday Life
Culinary and traditional uses
The fresh red petals of Rhododendron arboreum are used across the hills to make a tart, ruby-coloured juice and jam, often sold seasonally along trekking routes. The petals are also pickled or used in traditional recipes in some communities.
Symbolism
Lali Gurans appears widely in Nepali folk songs and poetry as a symbol of youth, beauty and the arrival of spring. It's also used informally as a symbol of national pride, appearing in event branding, tourism campaigns and provincial imagery — Rhododendron arboreum is also the state flower of Uttarakhand in India, reflecting its wider presence across the Himalayan belt.
Where to see it
- Annapurna region — Ghorepani–Poon Hill is Nepal's best-known rhododendron trail.
- Langtang National Park — dense rhododendron forest along the lower trail sections.
- Gosaikunda trek — passes through several elevation bands of bloom.
- Kanchenjunga Conservation Area — high species diversity, including rarer alpine varieties.
- Rara National Park — remote, less-visited rhododendron forest in far-western Nepal.
Conservation Status
Rhododendron arboreum itself is not considered globally threatened and remains widespread across its range. However, some rarer high-altitude Nepali species face localised pressure from habitat loss, unsustainable harvesting for firewood, and climate-driven shifts in flowering timing. Community forestry programmes in several districts now include rhododendron groves as protected areas, partly to support the growing rhododendron-viewing tourism season.
