Thanks to Shakespeare It’s most common to compare the beauty of a lover to a flower. Flowers have an ethereal and fleeting beauty incomparable to anything else in the world, the exception being those in the first flush of love. But unfortunately, many rare flowers in the world have already gone extinct in the wild and only exist in some pockets, thanks to the efforts of botanists and conservationists and might be available either in select places in the wild or in botanical gardens. The list also includes those flowers that bloom only once every few decades and those that require certain conditions to bloom, making them unique.

There are flowers that are rare because they have been bred a certain way over a period of years, like the rarest rose in the world, the Juliet Rose.

Anything rare and beautiful always draws crowds, people who travel great distances for a rare sighting of a rare bloom or to catch a glimpse of some unique flowers.

15 Rare Flowers In The World And What Makes Them So

1. Juliet Rose (Scientific Name Unknown): The Rarest Rose In The World

Juliet rose, rare roses

The Juliet Rose is not only considered to be one of the rarest flowers in the world, but it’s also the rarest rose in the world because it took 15 years for rose breeder David Austin to cultivate the flower in England. Additionally, it cost him a whopping $4.3 million to do so. A type of tea rose, the Juliet Rose has peach and apricot coloured petals. In full bloom, they open to reveal smaller blooms at the heart.

Some fun facts about Juliet Roses:

2. Ghost Orchid (Dendrophylax Lindenii): Florida’s Endangered Flower

Named after the shape of its petals, the Ghost Orchid is listed as one of the rare flowers of the world because it requires high temperatures and high humidity to grow, making it almost impossible to cultivate outside its natural habitat.

The plant has no leaves, does not depend on photosynthesis, and does not manufacture its own food. It has to be linked with another plant to get sufficient energy. The stem and flowers appear green in colour with whitish petals.

Ghost Orchids are found in Cuba, Florida and the Bahamas, and bloom only for three weeks between April and August. Even if you get close enough to the flower, you may not be able to spot a Ghost Orchid. The fact that most of its natural habitat is getting destroyed makes the Ghost Orchid even rarer.

Some fun facts about Ghost Orchids:
  • The ghost orchid is a rare flower that gives off a soap-like odour when in bloom.

3. Fire Lily (Gloriosa Superba): Zimbabwe’s National Flower

The Kadupul Flower is a cactus blossom that rarely blooms, and is therefore considered as one of the rare flowers in the world. Not only that, but it also blooms only at night and withers away by daybreak.

Kadupul flowers are large and beautiful, snowy white and star-shaped. It grows mainly in the wild, among decaying matter around trees, and can measure a massive 30 centimetres long and 17 centimetres wide. It also emits a pleasant smell. While some report that this flower grows only in Sri Lanka, others say that the Kadupul Flower can also be found in India, Japan, China and several Latin American countries. It is, however, close to impossible to find one in the wild, as it blooms rarely and only at night, and so spotting it is difficult. It’s said to be very beautiful and a truly rare flower to behold, making it a unique flower in India and the other regions. These flowers require specific conditions to grow in and are very expensive owing to their short lifespan. However, they are easy to cultivate.

As it can reach up to 3.6 meters in height, it’s also known as one of the largest flowers in the world. This flower has no roots, leaves or even a stem. Moreover, it seems to have only one petal, which is green on the outside and burgundy red on the inside and is shaped like a cone. When the corpse flower is in bloom it emits a foul odour, similar to that of rotting flesh or rotten meat, to attract flies and carrion beetles.

Corpse Flowers are found only in the low-lying rainforests of Indonesia. In captivity, they grow mainly in Sumatra gardens in Sumatra.

Some fun facts about the Corpse flower:
  • The corpse flower is so rare, blooming once in a few decades, that flocks of people gather at botanical gardens to see and smell them. It seems strange that people are willing to spend time and energy to smell something like rotten meat, isn’t it?

The Middlemist Red is one of the rarest and most beautiful flowers in the world; so much so, that only two of its samples exist today. The flower was evidently wiped out of existence in its native China sometime after it was brought to the United Kingdom. While there is no concrete explanation for why the plant went extinct in the wild, it is believed that over-cultivation might have had a key role.

The Middlemist Red is a beautiful flower that looks like a rose and is bright pink (contrary to what the name suggests). Although it looks like a rose, the Middlemist’s red is actually a type of Camellia flower. A native of China, it was brought to London in 1804. It’s now extinct in China, and only two known remaining Middlemist Red flowers are growing in captivity—one in a botanical garden in New Zealand and the other in a greenhouse in England.

Some fun facts about the Middlemist’s Red:
  • This red camellia flower was brought to England by a botanist named John Middlemist, giving it its name.
  • John Middlemist had sold quite a few of these beauties to the public when he first introduced them in the United Kingdom. So, there might be more of the Middlemist’s Red in gardens, unbeknownst to others.

The Rothschild’s Slipper Orchid is one of five types of Slipper Orchids (the name comes from the lower lip of the flower that resembles a slipper), which again is a sub-category of the orchid family.

11. Parrot’s Beak (Lotus Berthelotii): Winner Of The Award Of Garden Merit

Parrot's beak flower, rare flowers in the world

The Parrot’s Beak Flower is rare because it requires specific temperatures to bloom in; any fluctuation causes it to wither. It’s also believed to be extinct in the wild, much like most of the flowers on this list. Only a few members of this species of flower exist today; many might go extinct in the wild soon, making it one of the rarest flowers in the world. It is reported that the flower began to disappear (from the wild) in 1884.

Parrot’s Beaks are claw-shaped flowers that grow on trailing vines and are found in striking orange and red colours. They are known to measure up to one inch long. They resemble a parrot’s beak, hence the name.

Native to the Canary and Cape Verde Islands, these flowers are believed to be extinct in the wild but they can be cultivated in gardens, as well as indoors. These days they are typically grown for ornamental purposes.

The Parrot’s Beak blooms best in spring and requires a lot of sunshine (it may not bloom, or fewer flowers will bloom if grown in the shade) and cool temperatures. It also requires well-drained but moist soil as the roots can rot if not properly drained.

Some fun facts about the Parrot’s Beak Flower:
  • It won the prestigious Award of Garden Merit of the Royal Horticultural Society.

13. Black Bat Flower (Tacca Chantrieri): The Rarest Black Flower

Black bat flowers

The Black Bat Flower is the most unique flower in the world because it has the rarest flower colour, black. Measuring up to 30 centimetres in diameter, the flower resembles a bat, which is how it got its name. It has long droopy whisker-like stamens, which can measure up to 70 centimetres long.

The Black Bat Flower is found in Southeast Asia including Thailand, Malaysia, and southern China. The plant needs a lot of humidity and a large amount of water until it grows properly, which makes it a difficult plant to grow indoors.
