Pandargonium cyanellum

The sari is a lovely flowering plant with a simple structure consisting of one thick main stem, several whorls of leaves attached in a ring at intervals along the stem, and a large bud at the apex. The bud is actually a cluster of many flowers, or inflorescence, resembling a giant artichoke. Surprisingly, the body temperature of the plant is typically several degrees warmer than the surrounding air, which would be harmful for most other plants. To offset the higher body temperature and greater water loss that results from it, the plant stores water in its thick stem and roots. (Read more)
The sari is considered an early successional plant because it is often the first plant to emerge and grow on newly created soil after a volcanic eruption. Its high body temperature and unique means of dispersing seeds make it well adapted to this habitat. When the flowers in the giant inflorescence have been pollinated and the seeds are ripe, the entire inflorescence explodes open, dispersing seeds in all directions.

Animals and Na’vi have learned to recognize the sounds of this explosion and come to collect seeds to eat. Those that are not collected will germinate and readily grow new plants.
