Orchid flowers are fairly uniform in shape, with five spear-shaped to circular petals growing around a central formation that contains the stigma and stamen of the flower.
Blue orchid flowers do exist, but are very rare. When they are spotted, blue orchids are a deep, rich blue. Various purple orchids are also sometimes labeled as "blue."
Blue orchids have the same plant structure as other orchids, with a long, flexible shoot that supports the orchid flowers, and wide, spear-shaped leaves growing from the base of the shoot.
Orchids hail from the mountains of China and Japan. They became popular in Europe in the 19th century.
All orchid-growing needs are consistent, regardless of color. Orchids require temperatures of 50 to 90 degrees and restricted watering. They will die if they are watered too often or get too cold.
