Despite sharing the nickname “corpse flower,” they are different plants, and only one produces a single enormous true flower.
What makes these flowers look—and smell—so unusual?
There is no scientific measure of floral ugliness. The judgment is personal; the features are not. Rafflesia arnoldii has broad reddish-brown lobes marked with pale spots. Titan arum is known for a dramatic, sculptural floral display and an odor often compared to rotting flesh. Both can seem more unsettling than inviting, especially when their carrion-like smell is strongest.
That smell serves a purpose. Kew and the U.S. Botanic Garden describe carrion-like odor, sometimes accompanied by heat, as a way of attracting pollinators such as flies and beetles. What people may find repellent is part of each plant’s pollination strategy.
Rafflesia and titan arum are not the same “corpse flower”
The shared nickname can obscure an important botanical difference: Rafflesia arnoldii produces a single true flower, while titan arum’s famous display is an inflorescence—a cluster of many flowers arranged on a central structure. RBGE identifies Rafflesia arnoldii as the largest true flower; titan arum is notable for its huge unbranched inflorescence, not the world’s largest single flower.

Can you grow Rafflesia at home?
For practical purposes, no. Kew says almost no botanical gardens cultivate Rafflesia, including Kew itself, because the plant has extremely specific requirements. That does not establish that it has never been cultivated; it does show why an ordinary home growing setup is not a realistic prospect.
The key distinction is between an unusual-looking plant that needs careful conditions and one whose requirements are so specialized that even botanical gardens rarely grow it. Rafflesia belongs in the latter category. The available sources do not give a home-growing method or a simple set of household conditions that would make cultivation feasible.

Can you grow titan arum at home?
It is difficult, rather than categorically impossible. The Royal Botanic Gardens, Edinburgh (RBGE) says titan arum needs high temperature and humidity, conditions usually associated with a tropical glasshouse rather than a typical home. Kew says the plant grows best at about 22°C and 75% humidity. Those figures describe Kew’s stated preferred growing conditions, not a guarantee that a plant will flower if a home grower reproduces them.
Its size is a serious practical constraint
Kew reports that the inflorescence can reach up to 3 metres tall. RBGE also notes that the plant’s foliage may exceed six metres. A home grower would need to account for space as well as warmth and humidity; a small windowsill or ordinary room is not a realistic setting for a mature specimen.

The flower display is brief and unpredictable
Kew says the titan arum’s open bloom phase lasts 48–72 hours. Its 2026 press release quoted Solene Dequiret, Princess of Wales Conservatory Manager at Kew, saying: “It’s really hard to tell exactly when a titan arum will flower and they always keep us guessing until the very last minute, but we are confident it is a matter of days before this specimen opens.” A short, hard-to-predict bloom is part of the challenge for anyone hoping to witness the display.

Titan arum is also a conservation concern. The U.S. Botanic Garden, attributing its figures to IUCN, reports fewer than 1,000 wild individuals and a population decline of more than 50% over 150 years. The page does not give a publication year for those estimates, so they should not be read as figures newly issued in 2026. Botanic gardens maintain living collections and carry out conservation work, making their cultivation efforts relevant beyond public display.
