Sikkim Sundari:
Sikkim Sundari (Rheum nobile), a rare high-altitude Himalayan plant, has drawn attention for its unique biology and striking appearance. Rheum nobile, commonly known as padamchal, or Sikkim Sundari, is a giant herbaceous perennial plant native to the high-altitude alpine zones of the Himalayas (4,000–4,800 meters).Belongs to the Polygonaceae family and is found in North Sikkim (trekking routes near alpine passes and glacial valleys), Nepal, Bhutan, Tibet, and Myanmar. Typically grows on open alpine slopes, rock ledges, glacial valleys, and tundra-like environments. Its tall, translucent bracts form a natural glasshouse that traps heat, protects the flowers from freezing winds and intense UV radiation, and gives the plant a luminous, tower-like appearance against the Himalayan landscape.
