The world's rarest flowers: Ghost orchids
The rarest flower in the world is the ghost orchid, which is a very rare plant growing in Florida, USA. The ghost orchid has very demanding requirements for the growing environment, so artificial cultivation is almost impossible, and the ghost orchids that currently exist are wild. Moreover, the United States has ordered people to strictly prohibit the picking of wild ghost orchids, and now the number of ghost orchids is very small.
