Common Grasspink

The common grasspink is just that, very common. It is one of the most abundant native orchids in Eastern North America. It found north to Newfoundland, Canada, south to Cuba, west to Texas, and east to the Atlantic ocean. In Florida C. tuberosus occurs in 46 counties, but is found more common in north and central Florida. Flowers have a variety of colors from pale to dark pink, white, and lavender. Plants can be found in sunny sandy/moist ditches, wet meadows, and pine flatwoods. Populations of plants can be in the thousands. The blooming period in Florida is March (south) to August (north). All photographs were taken by Philip Kauth.

the common pink color. The upper lip petal with the yellow hair-like structures (photo on right) serves as a landing pad for pollinators, which are bees. The bees then fall onto the structure pointing straight out and collect the pollen.
