“The World’s Largest Flower: Rafflesia”

Rafflesia is the world’s largest, heaviest, rarest and one of the smelliest flowers in the world.

It grows to a width of one meter and weighs about 10 kg.

Rafflesia, native to the rainforests of Sumatra and Borneo in the Indonesian archipelago, is the largest flower in the world.

Interestingly, replazia is a parasitic plant without leaves, stems and roots (it only has nutrient-absorbing filaments to absorb nutrients from the host it lives on) but the largest flower.



Rafflesia is a huge speckled flower with five petals up to 106 cm in diameter and weighing up to 10 kg.

A replasia flower has a short life of 5-7 days.

Reflexia has its stamens and stamens fused together in a central column, producing a ring-shaped corona, or crown.

The smell attracts the carrion flies and then the pollination takes place.

After 9 months of maturity, a replantation plant opens into a cabbage-sized bud.

Facts about replasia

Rafflesia is the largest single flower.

Arum Titan bears the largest inflorescence.

Rafflesia is a parasite that attaches itself to a host plant, the tetrastigma vine, which only grows in undisturbed rainforests, to obtain water and nutrients.

The genus Rafflesia is named after the adventurer and founder of the British colony of Singapore, Sir Stamford Raffles.

Dr. Arnold remembered the species name as Rafflesia arnoldii.

Rafflesia is the official flower of Sabah in Malaysia, as well as for the province of Surat Thani, Thailand.

Rafflesia manillana, the smallest species in the genus Rafflesia also has flowers 20 cm in diameter.

Rafflesia flowers are unisexual.

Forest mammals and woodpeckers feed on 15 cm diameter replanted fruits, filled with smooth flesh and thousands of tiny, hard-coated seeds.

It is believed that rafflesia is related to poinsettias, violets, passionflower, and other members of the Malpighiales order.

The putrid smell of the flower emanates from the branched, tentacle-like ramenta, inside the corolla of the petals.

Replazia is an endangered or threatened species.

Rafflesia arnoldii does not have chlorophyll, as all green plants do, so it cannot undergo photosynthesis.

Since Rafflesia is one of the rarest plants on the planet, people started studying them since 1929.

They tried to cultivate the plant artificially, as the plant takes 9 to 21 months to flower a bud – only to last less than a week.

The biggest bloom

Similar to Rafflesia, which is the largest single flower, The titan arum – Amorphophallus titanum, is the largest unbranched inflorescence in the world of flowering plants.

The Italian botanist Edoardo Baccari discovered Titan Arum in Sumatra in 1878.

Arum Titan is also native to the rainforests of Sumatra.

Arum Titan belongs to the Arsea family.

Arum titan is also called a corpse flower due to its smell of rotting flesh when the flower blooms.

The arum titan plant can reach 7 to 12 feet tall and weigh 170 pounds.

In Arum Titan, both male and female flowers grow in the same inflorescence at the base of the spike.

The female flowers open first, then within a day or two the male flowers open.

This prevents the flower from self-pollinating.

In Titan Arum the spathe is green on the outside and dark burgundy red on the inside, and is deeply wrinkled.

The visible upper part of the spike is covered in powder, while its lower end is covered in bright red-orange folds.

When the titan arum reaches full bloom, the spike collapses from its own weight and the spa withers, perhaps never to bloom again.
