But even the most avid gardeners may not know about these, five of the world’s most rare flowers. With stunning blooms and fascinating histories, these plants are not ones you’re likely to see after the April showers bring May flowers. Pitcher Plant Istvan Kadar/Getty Images Found in Northern Queensland, Australia, this pitcher plant is from a species of tropical flesh eaters. In fact, botanical archeologists have witnessed it consuming mice, rats, and small lizards. The plant, whose known scientifically as Nepenthes tenax was discovered in Cape York and can grow up to 100 centimeters (40 inches), with vines growing to more than 25 cm (10 inches) high. Kadupul Flower The kadupul flower is also known as the night-blooming Cereus.

Kadupul flowers, scientifically known as Epiphyllum oxypetalum, are meaningful to followers of Buddhism, as it is believed that when the flowers bloom, the Nagas (semi-mythical Sri Lankan tribes) descend from their celestial abodes and present the flowers as an offering to Buddha. Middlemist’s Red Camellia Daniela Duncan/Getty Images This lush red flower was brought from China to the U.K. more than 200 years ago, and, though it survived during bombings in World War II, it is considered extinct in the wild. The only other variety of the camellia — named for the London gardener who collected it in 1804 — is found in New Zealand. The flower blooms a deep pink for about a month in the spring. The Middlemist and several other rare camellias are housed in a restored conservatory in Britain. Franklin Tree This is a Franklinia alatamaha at UBC Botanical Garden in British Columbia.

It has been extinct in the wild since the early 1800s and, though the cause is unknown, botanists and other scientists often cite fire, overcollection by plant collectors, or fungal disease. All the current Franklin trees are descended from the seeds collected from the gardener John Bartram, who first discovered it, and live in Philadelphia in Bartram’s Garden. The flowers bloom at the end of the summer. American Ghost Orchid The ghost orchid's roots inconspicuously anchor it to the bark of its host tree.

Since the roots blend in with the surroundings, the flowers seem to float like ghosts. These orchids are so rare because they can only be pollinated by one creature, the giant sphinx moth, and can only grow if their seeds land on a tree trunk covered in a specific type of moss. When the seeds of the orchid, which is considered endangered in the wild, do find a home, the flowers can bloom up to 10 at a time in the summer, before they lie dormant for several years.
