During spring, little clusters of yellow-green blooms complement the vertical ribs of stems. You can plant it in elevated planters and big pots. 

The candelabra tree is indigenous to South Africa’s coastal and inland areas, where it flourishes in arid and rocky settings. It matures into sculptural specimen plants that are employed as garden themes in well-drained soils. It can store rainwater from winter precipitation and requires only occasional summertime watering.

2. Oahu Stenogyne

Oahu StenogyneOahu Stenogyne also referred to as Stenogyne Kanehoana, is a rare flowering plant in the mint category. It is exclusive to Hawaii, where it can be found in Waianae Peak on the island of Oahu. It is a federally protected species in the USA. As such, it has to be one of the 10 rarest plants in the world.

This Hawaiian mint is a fuzzy plant that can grow up to 2 or 3 meters long. Its woolly leaves can grow up to 15 centimeters long and 5 centimeters broad. The plant produces tubular flowers that can grow more than 5 cm long. They are yellowish or pale in color and have purple or pink lips.

3. Middlemist Red

Middlemist RedThe Middlemist Red (Middlemist camellia) is thought to be the world’s rarest flowering plant, with only two known locations. One is in a garden in New Zealand and the other is in a conservatory in the United Kingdom. The Middlemist Red is of Chinese origin and was introduced to the United Kingdom by John Middlemist in 1804.

Even though the word “red” is in the name, Middlemist’s Red is a rich pink color. It is thought that additional instances of this species have persisted in people’s gardens. They went unnoticed as they were formerly marketed directly to the public by John Middlemist.

4. Encephalartos woodii

Encephalartos WoodiiEncephalartos woodii is a lovely plant and a rare one at that. Even in young specimens, the leaves are a deep lustrous green, 2–3 m long. They have an elegantly arching form, giving these cycads a dense umbrella-shaped canopy. 

Although the Kirstenbosch specimen is unbranched, older samples are frequently clustered at the top. Encephalartos woodii can grow up to 7 meters tall, with a trunk diameter of up to 950 mm at the base and 600 mm at the top.

It was discovered in 1895 on the outskirts of South Africa’s Ngoye Forest by John Medley Wood. He referred to it as “the most handsome of all” Encephalartos.

5. Tahina Palm

Suicide Palm or Tahina PalmThis unique plant was discovered in Madagascar by a farmer in 2005. Tahina Palm reaches a height of 18 meters and spreads around 15 meters to its surroundings.

The core reason for it being so famous is, its life! The total lifespan of this plant is 50 years! After blooming, it quickly dies.

In addition, there are only 90 such plants in existence.

Suicide Palm or Tahina PalmTahina palm, popularly known as Dimaka, is a species of Tahina Spectabilis. The palm is notable for its stunning end-of-life blooms. It is only found in Madagascar’s Analalava province, where it thrives in seasonally flooded marshlands. Xavier Metz, a Malagasy cashew producer, discovered the variety in 2008.

The Tahina palm has a large trunk that can reach a height of 20 meters. Its canopy of round fan leaves can grow up to 6 meters across. Rings of dead leaves wrap the tree beneath the crown of fresh growth, leaving ring scars on the trunk when they drop off. The species is estimated to live for 40-50 years.

6. Rothschild’s Slipper Orchid

Rothschild’s Slipper OrchidRothschild’s Slipper Orchid is a huge clear-leafed, rare flower species. It has a long inflorescence with up to 6 big flowers that blossom. It is the only Corypetalum species that holds its petals almost horizontally, giving the bloom a peculiar appearance. 

The flower features red and green speckled petals to lure parasitic flies that mistake it for a swarm of the aphids on which they lay eggs. As they attempt to do so, the flies rub against the stigma, shedding any pollen they have previously collected and then obtaining more from the other.

The blossoming season lasts from March to May. It can be found at heights ranging from 600 to 1250 meters above sea level in the jungles surrounding Mount Kinabalu in Northern Borneo.

7. Attenborough’s Pitcher Plant

Attenborough’s Pitcher PlantNepenthes Attenboroughii, sometimes referred to as Attenborough’s pitcher plant is a predatory pitcher plant of the Nepenthes family.

Beautiful and strange, it spends its whole life cycle underneath the Earth. The species possesses the least chloroplast genes of any plant, and they aren’t engaged in photosynthesis. 

The remaining genes and their roles may bring fresh insights into crucial plant processes. This rare orchid is extremely endangered, with only 50 known wild plants discovered in five Western Australian locales. The orchids’ locations are unknown due to their scarcity.

9. Kadupul Flower

Kadupul FlowerSri Lanka’s natural blossom, the Kadupul flower, is reputed to be the most expensive flower in the world. Because of its cactus roots, each Kadupul blossom has a very short existence and can only withstand the night before withering to naught by morning. That places it in our list of the top 10 rarest plants in the world. 

Despite this, the smell of the Kadupul is just breathtaking with some soothing abilities. The bloom itself has a lovely white and golden tint and develops to a maximum height of 30 cm. 

The blossoms of the Kadupul usually begin to bloom between 10 pm and 11 pm, extending the process by 2 hours. Once all the buds have opened, the flowers have a lovely aroma and bloom on full moon days once a month. It’s also known as the Flower from Paradise, the Queen of the Night, and even the Dutchman’s pipe.

10. Quiver Tree

In the summer, it has a beautiful look with yellow blossoms.

Climate change is threatening this plant species, which is why it is listed as Endangered by the IUCN (International Union for Conservation of Nature). The quiver tree, also known as Choje by the native San tribe, gets its name from the San practice of thinning out the tubular stems of Aloe dichotoma to construct quivers for their arrows.

Question: What makes a plant rare?

Answer: Rare plants can be termed as uncommon plants with their species’ entire population consisting of only a few specimens, or the species is confined to a limited geographical habitat, or both.

Question: What is the newest plant discovered?

Answer: On a secluded slope in Hawaii, botanists discovered a new type of orchid. Cyanea Heluensis is the name of the new plant discovered, which has white, curving blossoms. The plant is very rare and only one of its types has been discovered thus far.

Question: What would happen if all the plants in the world became extinct?

Answer: If all of the living species on earth perished, all of the living creatures on the planet would disappear too. Plants are necessary for the survival of humans and animals, providing them with oxygen to breathe. Mind you, plants are the primary source of oxygen required for survival.

Question: Are there any undiscovered plants?

Answer: Science has yet to discover the majority of the world’s species. As of 2010, biologists had described and categorized 1.7 million flora and fauna, accounting for fewer than one-quarter of the total number of species anticipated on the planet.

Question: Where can a rare plant be taken care of outside its natural habitat?

Answer: Botanical gardens and greenhouses are sites where rare species of plants can be cared for outside of their natural habitat.

Question: How many plants do you need to purify a room?
