15 Rare Flowers That Look Fake But Actually Grow in Gardens: Photos and Where to Source Them
From the flesh-smelling corpse flower to skull-forming snapdragon pods: discover 15 genuinely unusual flowers — which ones are impossible to grow, which are exotic but possible, and which bizarre blooms are hiding at your local nursery.
The most extraordinary designers on Earth never went to art school. Over 400 million years of evolution, flowering plants developed an arsenal of strategies to attract pollinators — and some of those strategies produced flowers so visually extreme that humans struggle to believe they are real.
These are not rare hybrids coaxed from a greenhouse. They are wild species: flowers that smell of rotting flesh to attract carrion beetles, flowers that mimic a female bee so convincingly that male bees attempt to mate with them, flowers that produce no nectar whatsoever and simply lie to their pollinators.
This guide divides 15 of the most genuinely unusual flowers into three groups: those that exist only in remote rainforests or specialist botanical gardens, exotic ones that determined US gardeners can actually grow, and genuinely bizarre flowers that are surprisingly easy to find at your local nursery. See our complete orchid growing guide and sunflower growing guide — two families with more than their share of unusual forms — and our flower meanings guide for the symbolism behind the world’s most striking blooms.
Flowers You Can’t Grow at Home (But Need to Know About)
The following five flowers exist in wild habitats so specialized, or are so dependent on specific ecological relationships, that no home gardener can meaningfully cultivate them. Understanding why they are impossible to grow illuminates something remarkable about plant evolution.
Seasonal Garden Calendar
Know exactly what to plant, prune and sow — every month of the year.
1. Corpse Flower (Amorphophallus titanum)
Native to: Sumatra | Growable at home? No — specialist tropical greenhouse only
The corpse flower holds two simultaneous records: the largest unbranched inflorescence on Earth (the flower spike can reach 10 feet tall and 4 feet wide) and one of the most spectacularly unpleasant smells in the plant kingdom. The scent combines rotting flesh, camembert, and sweaty socks — designed to attract the carrion beetles and blow flies that pollinate it.
The mechanism goes further. During its 24–48 hour bloom window, Amorphophallus titanum actively heats itself, reaching temperatures close to 98°F (36°C) — almost exactly human body temperature. This thermogenesis volatilizes the scent compounds more efficiently and mimics the warmth of a freshly dead mammal to deceive carrion-dependent pollinators more completely.
All of this happens after the plant spends 7–10 years storing energy in an underground corm that can weigh over 100 pounds. When it finally blooms, it does so for just one to two days before collapsing entirely. According to Kew Gardens, fewer than 1,000 individual plants are believed to survive in the wild in Sumatra, where ongoing deforestation continues to shrink its habitat.
The surprising fact: The heat it generates matches human body temperature almost exactly — a convergence so precise it is still not fully understood by botanists.
2. Jade Vine (Strongylodon macrobotrys)
Native to: Philippines | Growable at home? Zone 11+ or large tropical greenhouse only
The jade vine produces one of the most improbable colors in the plant kingdom: a luminous turquoise-blue-green that photographers consistently report they cannot capture accurately — no camera sensor processes the wavelength the way the human eye does. The flowers hang in racemes up to 3 feet long, each bloom shaped like a curved claw, and that shape is an adaptation that makes perfect evolutionary sense once you know the pollinator.
The jade vine is bat-pollinated. At night, bats fly through the Philippine rainforest canopy and hang upside down from the flower clusters to feed on nectar. The claw shape hooks around their feet, ensuring pollen transfer with each visit. It is a flower shaped specifically to fit the anatomy of an animal that approaches it inverted.
The jade vine is critically endangered — its native rainforest in Luzon has been reduced by deforestation to the point where wild populations are barely viable. It survives primarily in botanical gardens worldwide, where it has become a flagship conservation species. Growing it requires Zone 11 temperatures or a very large tropical greenhouse — a plant you are far more likely to visit at a botanical garden than own.
The surprising fact: Its turquoise color is practically unique in the plant kingdom — virtually no other plant produces that specific blue-green wavelength at that intensity.
3. Ghost Orchid (Dendrophylax lindenii)
Native to: South Florida, Cuba | Growable at home? Virtually impossible
The ghost orchid does not have leaves. Unlike virtually every other plant on Earth, it photosynthesizes entirely through its roots — flat green roots that cling to the bark of specific trees in the cypress swamps of south Florida and Cuba. The flower — white, ghostly, with long trailing petals — appears to float in mid-air with no visible attachment to anything. The common name is not metaphor; it is an accurate description.
The pollination mechanism is equally improbable. The ghost orchid produces no nectar. Instead, it releases a scent at night that mimics the pheromones of an apple snail — the preferred food of the giant sphinx moth (Cocytius antaeus), the only insect with a tongue long enough (up to 8 inches) to reach the flower’s nectarless spur. The moth investigates, picks up pollen, visits another ghost orchid, and the plant reproduces entirely by deception. No reward is ever offered or delivered.
Cultivation is effectively impossible: specific host trees, humidity above 80%, and a microclimate that exists only in south Florida’s cypress swamps are all required. The ghost orchid also starred in Susan Orlean’s The Orchid Thief (1998) — adapted into the film Adaptation (2002) — which triggered a wave of illegal poaching that has further reduced wild populations.
The surprising fact: In the wild, a single ghost orchid bloom may go unvisited for years if the sphinx moth doesn’t locate it — the deception requires a very specific victim.
4. Rafflesia (Rafflesia arnoldii)
Native to: Borneo, Sumatra | Growable at home? Never — impossible to cultivate
Rafflesia arnoldii holds the world record for the largest individual flower — up to 3 feet (1 meter) in diameter and weighing as much as 24 pounds (11 kg). But what makes it genuinely extraordinary is not its size: it is the fact that the plant is entirely invisible for most of the year.
Rafflesia is a holoparasite. It has no roots, no stems, no leaves, and no chlorophyll — it cannot photosynthesize at all. It lives as invisible thread-like filaments woven through the tissue of its host vine (Tetrastigma species), absorbing water and nutrients entirely from another organism. The only sign of its existence is a small bud that swells over 9–12 months before bursting open as the enormous, reddish-orange, leathery flower — which, like the corpse flower, smells powerfully of rotting meat to attract carrion flies.
According to the Missouri Botanical Garden, Rafflesia has never been successfully cultivated outside its native habitat. The filaments are so intertwined with the host vine that separation — and therefore propagation — appears to be impossible with current techniques.
The surprising fact: British naturalist Joseph Arnold first documented it in 1818 during an expedition led by Stamford Raffles — and died just days after the discovery, never seeing it again.
5. Youtan Poluo — The “3,000-Year Flower” (Gently Debunked)
Origin: Buddhist mythology | Reality: Lacewing insect eggs, not flowers
In Buddhist texts, the udumbara is said to bloom only once every 3,000 years, heralding the arrival of a great king or the birth of a Buddha. Every few years, viral photographs circulate showing tiny, impossibly delicate white “flowers” appearing on glass, steel, or fabric — claimed to be the legendary bloom.
They are not flowers. They are the egg casings of lacewing flies (Chrysoperla species) — tiny spherical eggs mounted on hair-like stalks — which genuinely do look like miniature otherworldly flowers at macro scale. The confusion is understandable; the image is undeniably beautiful.
The real botanical candidate for the udumbara, Ficus racemosa, has its own genuinely unusual biology: its flowers grow inside a closed fig-like structure called a syconium, accessible only to fig wasps with body shapes evolved specifically to enter the tiny opening. You will never see its flowers without cutting the fruit open. In this sense, Ficus racemosa earns its mythology: its flowers are genuinely invisible to casual observation.
The surprising fact: The Chrysoperla eggs are so consistently beautiful that the misidentification recurs in news cycles every few years, usually starting in Asia before spreading globally.
Exotic but Growable in the US
These five flowers are genuinely unusual and not widely grown — but determined US gardeners can obtain and cultivate them with the right conditions. Most require specialist sourcing; a few are increasingly available at better garden centers.
6. Black Bat Flower (Tacca chantrieri)
USDA Zones: 10–11 outdoors; houseplant elsewhere | Difficulty: Moderate to challenging
No plant in cultivation produces a more theatrical effect in a pot than the black bat flower. The flowers are near-black — more precisely, the deepest possible burgundy-maroon that functions visually as black — with two large wing-like bracts extending above them, and long, wispy filaments called “whiskers” that can reach 12 inches in length trailing downward like the legs of a giant insect.
The dark color and whiskers are not decorative accidents. Tacca chantrieri is fly-pollinated and uses visual deception: the entire arrangement mimics a rotting plant environment to attract the specific flies that pollinate it. True black does not exist in flowers — plants cannot produce a pigment that absorbs all visible light, because they need light to survive. What we perceive as “black” in flowers is always the deepest possible concentration of dark red or purple anthocyanins.
In the US, grow the black bat flower outdoors only in Zones 10–11. In colder zones, it makes a dramatic houseplant. Requirements: shade, high humidity above 60%, and consistently moist but well-drained soil. A steamy bathroom works remarkably well. Fertilize lightly with a balanced liquid fertilizer monthly during the growing season.
7. Chocolate Cosmos (Cosmos atrosanguineus)
USDA Zones: 7–10 | Difficulty: Easy to moderate
The chocolate cosmos is the botanical world’s closest approximation to a tragedy. Native to Mexico, this species has been extinct in the wild since approximately 1902 — and every single plant alive today, in every garden, nursery, and botanical collection worldwide, is a vegetatively propagated clone descended from one plant collected in the 19th century.
The species cannot produce viable seed because its sterile triploid genetics prevent normal meiosis. It survives only because gardeners keep dividing and propagating that single original clone, generation after generation, across more than 120 years.
What makes it worth growing despite this history is the combination of dark, velvety burgundy-chocolate flowers and a genuine vanilla scent — it produces vanillin compounds, the same chemical responsible for vanilla extract’s fragrance. It is a remarkable sensory experience: a flower that smells exactly like baking.
Grow in USDA Zones 7–10 as a tender perennial. In Zones 5–6, dig the tubers before first frost and store them frost-free over winter. Full sun, well-drained soil, and regular deadheading keep it blooming from July through October.
USDA Zones: Cool greenhouse required | Difficulty: Expert
The Dracula genus contains over 120 orchid species native to the cloud forests of Ecuador, Colombia, and Peru. The name “Dracula” comes from the Latin for “little dragon” — a reference to the long, fang-like extensions on the three sepals that form the flower’s outer structure. The species name vampira adds to the theatrical effect: blood-red markings on near-black sepals that produce an effect of genuine menace.
The most scientifically remarkable aspect of Dracula orchids is their pollination strategy: they mimic mushrooms. The flowers hang downward from pendulous stems, positioned unusually low — at or near the forest floor rather than elevated as most orchids are — and release a scent that mimics decaying fungus. Fungus gnats, attracted by both the smell and the visual resemblance to mushroom caps, visit and transfer pollen.
Growing Dracula orchids requires cool temperatures (45–65°F year-round), very high humidity (70–80%), and bright indirect light. In the US, this typically means a dedicated cool greenhouse, a climate-controlled basement grow room, or a naturally cool and foggy coastal zone in northern California or the Pacific Northwest.
9. Monkey Face Orchid (Dracula simia)
USDA Zones: Cool greenhouse required | Difficulty: Expert
Dracula simia achieves something no other plant does: its arrangement of column, petals, and lip creates an unmistakable portrait of a monkey’s face — complete with wide-set eyes, a nose, and a small mouth. It is one of those rare natural objects where the photograph requires no caption. Every viewer understands immediately.
The resemblance is genuine and consistent across all specimens, but it is not thought to be a specific evolutionary adaptation. It is more likely an example of pareidolia — the tendency to perceive faces in random arrangements — operating on a flower that happens to have face-like proportions. The actual pollination mechanism is olfactory: D. simia releases a scent resembling fresh orange blossom that attracts specific insects by smell rather than visual mimicry.
Like other Dracula species, the monkey face orchid is a cloud forest specialist requiring cool temperatures (below 65°F) and very high humidity year-round. It grows at elevations of 3,300–6,500 feet in Ecuador and Peru. Most US gardeners who successfully grow it use a dedicated cool greenhouse with a fogger to maintain humidity above 70%.
10. Parrot Flower (Impatiens psittacina)
USDA Zones: Zone 10+ | Difficulty: Effectively impossible to source legally
In 1901, botanist Sir Joseph Hooker described an Impatiens from Chiang Mai, Thailand, as resembling “flying parrots in full plumage” — and the common name has stuck. The flowers of Impatiens psittacina combine magenta and purple in an arrangement where the hooded upper petal, reflexed side petals, and curved spur produce the unmistakable silhouette of a parrot in flight.
The parrot flower occupies a very restricted range across northern Thailand, Myanmar, and a small area of northeast India. Thailand has banned the export of plant material entirely, making it essentially unobtainable for US gardeners through legal channels. Specimens occasionally appear at specialist botanical society sales, but their provenance deserves scrutiny.
For US gardeners wanting an alternative: Impatiens niamniamensis (Congo cockatoo) — which is legally available — produces pendulous red-and-yellow flowers with a similarly eccentric form. Grow it as an annual or Zone 10 perennial in high humidity and indirect light.
Unusual but Easy to Grow
These five plants are widely available, reliably cultivatable in the US, and genuinely bizarre — yet most gardeners walk past them without registering what makes them remarkable. They deserve a closer look.
11. Bleeding Heart (Lamprocapnos spectabilis)
USDA Zones: 3–9 | Difficulty: Easy
The bleeding heart’s flower shape looks like a jeweler designed it rather than evolution. Each bloom is a precisely formed pendant heart — rose-pink or white — with a small inner petal protruding from the base like a single teardrop. The biological purpose is elegant engineering: the heart shape positions a visiting bee’s antennae at exactly the right angle to contact the pollen-bearing structures inside.
Grow in USDA Zones 3–9 in partial to full shade with moist, humus-rich soil. The bleeding heart is a classic spring ephemeral — brilliant in April and May, then dying back completely by midsummer. Plant summer-active perennials (hostas, ferns, astilbes) around it to fill the gap. The white-flowered form ‘Alba’ is equally striking and slightly more vigorous in warm summers.
12. Passion Flower (Passiflora incarnata)
USDA Zones: 5–9 | Difficulty: Easy
When 16th-century Spanish missionaries encountered the passion flower in South America, they immediately saw a catechism: the 10 petal-like structures represented the 10 faithful apostles (excluding Judas and Peter), the corona of purple filaments was the crown of thorns, the 3 stigmas were the 3 nails of the crucifixion, the 5 stamens were the 5 wounds, and the tendrils were the whips. The name Passiflora dates from this interpretation — making it one of very few flowers named after perceived religious symbolism rather than botanical character.
The actual flower is among the most structurally complex in cultivation: a flat plate of petals surmounted by a radiant corona of filaments, with the pollen-bearing structures elevated on a gynostemium above everything else. Grow Passiflora incarnata in USDA Zones 5–9. It dies back to the ground in winter in colder zones but re-sprouts vigorously each spring. Full sun, well-drained soil, and a fence or trellis are all it needs. Be aware that it spreads by underground runners — plant where you can contain it.
13. Bird of Paradise (Strelitzia reginae)
USDA Zones: 10–11 outdoors; houseplant elsewhere | Difficulty: Easy
Named after Charlotte of Mecklenburg-Strelitz, Queen consort of George III, the bird of paradise produces one of the most immediately recognizable flower shapes in horticulture: orange sepals and blue petals arranged to precisely replicate the head and plumage of a tropical crane.
The resemblance is functional. In South Africa, where Strelitzia reginae is native, sunbirds land on the blue petal-perch and their weight pressing down causes the petals to separate, exposing the pollen-covered anthers hidden inside. The bird is the mechanism — without it, the flower cannot self-pollinate.
Grow in USDA Zones 10–11 outdoors, or as a dramatic houseplant in colder zones in a bright, sunny position. Drought-tolerant once established. Key tip: Strelitzia blooms most reliably when slightly root-bound — a pot-bound plant in bright light outperforms one in a generously sized container every time.
14. Snapdragon Skull Pods (Antirrhinum majus)
USDA Zones: Annual all zones; perennial in Zones 7–10 | Difficulty: Very easy
In life, the snapdragon is a cheerful cottage garden plant in every color except blue, and one of the most rewarding cut flowers a gardener can grow. But allow the flowers to go to seed and dry completely, and the empty seed pods that remain look startlingly like tiny human skulls — complete with hollow eye sockets, a prominent brow, and an open mouth. The effect is discovered anew every autumn by gardeners who left a row standing too long.
The biology is straightforward: the dried calyx forms the skull’s brow and eye-socket structure, the open seed capsule forms the mouth, and the papery remnants of the corolla create the face’s contours. It is coincidental — but so consistent across all Antirrhinum species that it has become a celebrated natural curiosity. See our guide to snapdragon meaning and symbolism for more on its dark mythology, which long predates the skull discovery.
Grow as a cool-season annual in all zones, seeding in late winter indoors for spring bloom. Allow some plants to set seed and dry in autumn for the skull display — then save the seeds for next year.
15. Bee Orchid (Ophrys apifera)
USDA Zones: European native; difficult in the US | Difficulty: Challenging to establish
The bee orchid has evolved a flower so convincingly bee-shaped that male bees attempt to mate with it — a phenomenon botanists call pseudocopulation. The velvety, textured lip mimics the abdomen of a female Eucera bee in both appearance and chemical scent, triggering the male’s mating behavior while depositing pollen on his body. No reward is offered or delivered.
The evolutionary twist is one of botany’s great ironic footnotes: in the United Kingdom, where the bee orchid grows most commonly on chalk grasslands and disused industrial land, the Eucera bee it evolved to mimic has been locally extinct for centuries. UK bee orchids now self-pollinate instead — the long, curved pollen masses fall onto the stigma unaided, in a kind of evolutionary redundancy. The deception apparatus evolved for a pollinator that no longer exists in that range.
For US gardeners: Ophrys species are occasionally available through specialist European terrestrial orchid nurseries but are notoriously difficult to establish outside their native chalk or limestone grassland conditions. Native North American orchids in the Platanthera, Calopogon, and Spiranthes genera are far more cultivatable alternatives for orchid enthusiasts. For the full family story, see our orchid growing guide.

Frequently Asked Questions
What is the rarest flower in the world?
Several species compete depending on how you define rarity. The ghost orchid (Dendrophylax lindenii) has fewer than 2,000 known wild specimens in south Florida and Cuba. By most measures of cultivated rarity, the Middlemist Red (Camellia japonica ‘Middlemistii’) takes the title — only two specimens are known to exist: one at the Chiswick Garden in London and one in New Zealand. It was brought from China to England around 1804 by horticulturalist John Middlemist and has never been rediscovered in the wild.
Can I grow a ghost orchid at home?
No — not meaningfully. The ghost orchid requires specific host trees (pond apple, pop ash), humidity consistently above 80%, and a microclimate that exists naturally only in south Florida’s cypress swamps. Even botanical gardens with specialist tropical facilities struggle with it. The ghost orchid also produces very few viable seeds, making propagation exceptionally difficult even under ideal conditions.
Which flowers look like animals?
Several on this list: the monkey face orchid (Dracula simia) resembles a monkey’s face, the bee orchid (Ophrys apifera) mimics a female bee with velvety precision, the bird of paradise (Strelitzia reginae) replicates a tropical crane, and the parrot flower (Impatiens psittacina) creates a parrot silhouette. Beyond this list: the flying duck orchid (Caleana major, Australia) resembles a duck in flight with remarkable fidelity, and the dove orchid (Peristeria elata, Panama) conceals a perfect dove figure inside its bloom.
What is the smelliest flower in the world?
The corpse flower (Amorphophallus titanum) is the most famous, but the competition is fierce. Rafflesia arnoldii smells equally of rotting meat. Closer to home, the dragon arum (Dracunculus vulgaris) grows in USDA Zones 5–8 and produces an overwhelming rotting-flesh smell for 24–48 hours, actively heating itself to spread the scent — exactly like the corpse flower. It is one of the most genuinely unpleasant garden experiences available to a US gardener, and some grow it specifically for the spectacle.
Which unusual flowers are easiest to grow in the US?
Bleeding heart (Zones 3–9), passion flower (Zones 5–9), and snapdragon (annual, all zones) are widely available and straightforward to grow from any nursery. Chocolate cosmos (Zones 7–10) requires only that you store the tubers over winter in cold zones — the rest is straightforward. For something even more dramatic, the spider lily (Hymenocallis festalis, Zones 7–10) and black-eyed Susan vine (Thunbergia alata, annual all zones) offer unusual structural forms with minimal effort. See our sunflower growing guide for another unusually large and dramatic flower that is deceptively easy to grow.
