The Corpse Flower, the tallest and possibly the smelliest

•The gigantic Himalayan Rhubarb (Rheum nobile) grows 0.9–1.2 m (3–4 ft) long. It is found even at heights of 4,268 m (14,000 ft) in the Himalayan ranges.

•The corpse flower (Amorphophallus titanum) or ‘titan arum’ is the tallest flower in India, and largest by diameter, though not a native species. It blooms once in nine years and while it is in bloom, the flower emits a strong odour similar to rotting meat or, aptly, a decaying corpse. The plant itself grows to around 3-4.6 m (10–15 ft).
