When it comes to wildflowers, few are as striking as orchids. Their unusual structures, vivid patterns, and bright colors bring natural beauty to any environment. While the most famous varieties are native to the tropics, there are many native to North America, too.
One of the most widely occurring orchid species in North America is Calopogon tuberosus – the "grass pink" orchid. It is found in bogs, meadows, swamps, and other wetland habitats throughout the eastern half of the United States and Canada. The plant earned its name from its grass-like leaves and magenta or pink flowers. Grass pink orchids are up to two and a quarter feet tall with grass-like leaves up to a foot long. The flowers grow from a central stem (also known as a spike) and number from two to 15 blooms per plant.
Grass pink orchids are pollinated primarily by bumblebees and other large long-tongued bees. Other pollinators may be attracted to the flowers, but their size and shape rarely allows them to transfer pollen. While most orchid flowers have the same orientation, the grass pink orchid's blooms appear upside down when compared. While not completely invulnerable, the grass pink orchid has remained relatively untouched by environmental threats. It is likely they will be around for everyone to enjoy for generations to come.
