The Rafflesia Plant - The Largest Carnivorous Flower in the World

Have you seen the largest flower in the world? In the tropical rainforests of Borneo, there is an amazing parasitic exotic plant called the Rafflesia which produces the most gigantic flowers in the world. This unique plant was named after Sir Thomas Stamford Raffles who was the governor of Sumatra in the early 1800s and most famously known for his founding of Singapore.

The unusual Rafflesia plant has no leaves, stems or roots. Being endoparasitic, the Rafflesia attaches itself onto a host plant for nutrients and survival. The host plant is the Tetrastigma vine that grows only in the primary rainforests. This makes the Rafflesia very rare and hard to locate. Besides, it is even more difficult to see the Rafflesia blooming. There will be a lot of travelling and jungle trekking to get to this plant as the blooms are usually found in higher altitudes.

A Rafflesia bud can take up to one year to develop before it transforms into a magnificent giant flower measuring almost one metre across. One single flower can weigh up to a massive 11 kg in weight. A typical Rafflesia flower consists of five huge fleshy leathery petals that are red in colour with wart-like mottles. The centre of the flower contains a disc with many vertical spines. The gigantic flower will stay open for about five days after which it will start to wilt. The red colour starts to change and turns brown. Finally it becomes black and collapses into a big slimy mass.


The Rafflesia plant is also called "corpse flower" or "meat flower" by the locals because the giant flowers smell like rotting flesh in the advanced stage of decomposition. The pungent smell attracts insects like bugs and flies to the flowers to assist in pollinating the male and female flowers so that more Rafflesias will continue to grow.

There are several species of Rafflesia found in the jungles of Borneo, Peninsular Malaysia, Sumatra, Thailand and Philippines. All the species are endangered and threatened by logging, ethnobotanical collecting and burning of primary forests especially in Borneo and Sumatra.

In recent years, conservation of the Rafflesia has been given a priority in the state of Sabah in Malaysia as this unique plant is on the endangered species list and is on the brink of extinction. Areas inhabiting the Rafflesia are now being monitored and protected in the country.

Interesting hub!

We actually have one here in a forest near my city. They say it's a meter across and really smells gross. Ugh! But they are really beautiful when you can't smell them.

I never had the chance to see one in person.

Moira, thank you for dropping by and commenting. You are lucky to have such a rare plant in your country. People around the world have to pay lots of money and travel to Borneo to see this flower.

Your hub just made me remember about rafflesias in the Philippines. Rafflesia was thought to be extinct in the country as early as 1882. But thanks to the efforts of Filipino scientists, it was discovered that this rare flower still grows in high peaks in several provinces. Even mountaineers have discovered rafflesia in unlikely places and mountains in the Philippines :)

kerlynb, yes, the Philippines is one of the countries that has this rare flower. It is likely to be found in the thick jungles that are inaccessible by people. Thank you for stopping by and leaving comment.
