Some plants smell like rotting meat; others bring to mind vomit or a hot garbage heap. Here are five striking examples—but not a scientific strongest-to-weakest ranking. Their odors come from different plant parts, and in several cases a smell that repels people helps attract animals involved in pollination or seed dispersal.
Why do some plants smell so bad?
Odor is a signal, not a verdict: what humans find revolting can resemble food or a breeding site to an insect. Carrion-like floral scents, for example, can draw flies that carry pollen between flowers. A pungent fruit may also attract animals that help disperse seeds. The five plants below are notable for their smell, but the available accounts do not establish a measured comparison of odor intensity.
Five plants with famously unpleasant smells
1. Rafflesia: a flower that smells like rotting meat
Rafflesia spends most of its life hidden inside Tetrastigma vines. When it blooms, its flower gives off a rotting-meat odor. Royal Botanic Gardens, Kew says the flower generates heat that helps carry the scent. Carrion flies drawn to it can pick up sticky pollen and transfer it to other flowers—a useful example of a foul smell serving a biological purpose.
2. Titan arum: the other “corpse flower”
The titan arum (Amorphophallus titanum) is native to Sumatra and is also called the corpse flower. Like Rafflesia, it produces heat and a rotten-meat smell, but the two are separate plants, not two names for the same species. The titan arum’s monumental structure is technically an inflorescence—a cluster of smaller flowers—rather than one single flower. Kew notes that deforestation in Sumatra puts the species at risk of extinction.

Ginkgo (Ginkgo biloba) is widely grown as an ornamental tree, but fallen, rotting fruit can smell pungent. Kew attributes the odor to butyric acid and compares it to vomit or sweat, as well as parmesan and butter. The smell belongs to the fruit, not the foliage; a gardening source notes that female, fruit-producing trees are the pungent ones. Kew presents animal-assisted seed dispersal as a likely explanation for the odor, rather than a proven account.
#1 Best Overall
- The Plant That Responds - Grow Mimosa pudica, the Sensitive Plant with delicate green leaflets that fold after a gentle touch and may produce rounded pink-to-lilac flower heads in suitable conditions. Grows 20-28 inches tall.
- 100-Seed Coverage Range - 100 seeds can support about 31-109 SQFT at the recorded 15-inch spacing using a 20-70% productive-plant range; actual coverage varies with germination, spacing, weather, and care.
- Hot-Water Prep For Hard Seeds - Place seeds in a heat-safe cup, pour just-boiled water over them, let the water cool, and soak overnight. Sow about 1/8 inch deep in well-drained mix; keep lightly moist.
- Warm, Bright Start - Use bright light and target a 75-95 F seed-zone range; protect the mix from prolonged 100 F+ heat and drying. Emergence can be uneven over 7-30 days, so steady moisture and patience matter.
- 100 Seeds In A Waterproof Packet - You receive seed, not live plants, in an RDR packet with planting guidance; store unused seed cool and dry and protect this frost-tender plant from cold.
4. Sausage tree: a night-scented flower
The African sausage tree (Kigelia africana) has an unpleasant-smelling flower whose odor is more noticeable at night. Kew suggests that the timing may appeal to bats. The red flowers can also attract birds and insects by day. Despite the tree’s common name, its fruit is poisonous to humans; elephants, giraffes and monkeys eat it.
5. Aristolochia goldieana: a flower like a hot garbage heap
This tropical West African climber has a flower with an odor Kew describes as like a garbage heap in hot weather. In a June 2024 article, Kew author Brie Langley wrote: “While the foliage smells bitter and of chemicals, the flowers smell like a garbage heap in high summer.” Small flies and gnats enter the flower’s tube, which is lined with hairs. They may remain trapped for up to 24 hours while the flower receives pollen and later releases its own.

How these plant odors differ
| Plant | Smelly part and description | Possible role of the odor |
|---|---|---|
| Rafflesia | Flower; rotting meat | Attracts carrion flies that can carry pollen between flowers. |
| Titan arum | Inflorescence; rotten meat | Its scent and heat resemble a carrion cue; the cited account does not specify a pollinator mechanism. |
| Ginkgo | Fallen, rotting fruit; pungent, compared with vomit or sweat | Kew suggests animal-assisted seed dispersal as a likely explanation. |
| African sausage tree | Flower; unpleasant odor, more noticeable at night | Kew suggests the timing may appeal to bats; flowers also attract birds and insects during the day. |
| Aristolochia goldieana | Flower; like a garbage heap in hot weather | Flies and gnats enter the flower and can be held while pollen is received and released. |
There is no single “real” corpse flower
Both Rafflesia and titan arum are commonly called corpse flowers because of their carrion-like odors. They are distinct plants with different structures: Rafflesia’s example is a flower, while the titan arum’s showy structure is an inflorescence. The shared nickname does not make them the same species.
Why “stinkiest” depends on the list
There is no standardized odor-intensity ranking across these plants in the cited accounts. Smell descriptions such as “rotting meat,” “vomit” and “garbage heap” are sensory comparisons, not measurements. Different lists also choose different plants: a Homes & Gardens feature published on 12 April 2025 names Bradford pear, crown imperial, sea holly, cleome and eastern skunk cabbage. The selection depends on the list’s purpose, not a settled botanical leaderboard.

A striking age claim about ginkgo
Kew’s 2024 smelly-plants feature says ginkgo trees first evolved over 200 million years ago and have remained almost unchanged. That is Kew’s published figure; the cited feature does not provide a cross-check of the dating claim.
