There are black orchids in existence, but they are very rare, according to the Online Flowers Guide. The destruction of their natural habitat is the reason for their rarity.
Black orchids grow six to 12 inches tall, prefer partial sun environments, and bloom from July to September, according to Online Flowers Guide. They need a warm environment to grow, where there is not an abundance of heat or cold.
The flower is seen as a symbol of virility, as the name comes from the Greek work "orchis" which means "testicle," according to Online Flowers Guide. Black orchids can grow this color naturally or white orchids can be dyed black, to achieve a similar effect.
