Top 10 Rarest Orchids in the World

Orchids are one of the most popular and most fascinating flowers in the world. They are always present on the list of the most expensive and rarest flowers. This is because of their unique beauty and because their species are so rare that they can only be seen once in hundreds of years.

The orchid family (Latin name Orchidaceae) is one of the two largest families of flowering plants, along with the Asteraceae. There are between 21,950 and 26,049 currently accepted species. They are perennial herbs with no woody structure. Orchids are mostly known because of their mesmerizing flowers, which come in many structural variations, colors, and fragrances.

Although part of a huge family, many orchids are critically endangered and rarely seen in nature. These 10 species we are sharing today are some of the rarest flowers in the whole world, so take a look at them and enjoy their unique beauty.
