Rafflesia - Largest Flower in the World
The Rafflesia is the largest flower in the World with recent flowers found measuring up to 95cm (3 feet) across. There are 55 species of Rafflesia, of which 9 are found in Borneo.Alongside their rarity, size and unusual appearance, it is the strange lifestyle of Rafflesias that make them so fascinating. The Rafflesia is a totally parasitic flower. The only visible part of the plant is a single flower that has no leaves, stems or roots.
The cabbage like bud of the Rafflesia lies apparently 'dormant' for up to 16 months before blooming. Once a bud reaches maturity, it begins to uncurl at night, although the process may take between 12 to 48 hours to complete. From this point the clock is ticking for the next generation of Rafflesias to be conceived, as after just 8 to 10 days the bloom of the Rafflesia begins to show significant signs of deterioration. During this short blooming period, the flowers are assumed to be pollinated by blue bottles and carrion flies. These are attracted by the sight of the bloom and its smell, which resembles rotting flesh. Pollination has to take place very quickly, as the blooms do not last very long. For pollination to occur successfully, both male and female flowers must be in bloom simultaneously in the same area, so that flies can pass between them.
There are two localities in Sabah that provide a reasonable opportunity for seeing blooming Rafflesia:- At private plots near Poring Hot Springs (on the lower slopes of Mount Kinabalu). The owners of the plots nurture the vines on which Rafflesia grow. During a day trip to Kinabalu Park and Poring Hot Spring you may stop at one of these plots.
- Tambunan Rafflesia Reserve in the Crocker Range to the south East of Kota Kinabalu. Only if there is a flower in bloom will visitors be allowed in to the Reserve. You can telephone the Centre in advance to check the current situation.
