The rare Sikkim Sundari, scientifically known as Rheum nobile, is a unique Himalayan plant found at high altitudes. This 'glasshouse plant' features translucent bracts that protect its flowers from harsh conditions. It is monocarpic, flowering only once after 7 to 30 years of growth before dying. Anand Mahindra highlighted its 'masterclass in patience' and its poignant reminder of fragile Himalayan ecosystems.
