Grass Pink Orchid
(Calopogon tuberosus)

Species Description
Description:
One of the most striking and sophisticated wildflowers in the North, the Grass Pink is a native terrestrial orchid. Unlike many other orchids that hang their heads, this beauty stands tall with a cluster of vivid, hot-pink-to-magenta flowers that appear to be growing "upside down" compared to other orchid species.
Habitat in the ANF
This is a specialist of acidic wetlands. In the Allegheny National Forest region, you won't find this in the deep, dry woods. Instead, look for it in specialized habitats like sphagnum bogs, fens, and very wet, peaty meadows. It often grows alongside carnivorous plants like Pitcher Plants and Sundews, thriving in nutrient-poor soils where its specialized roots give it a competitive edge.
Ecology and The Great Bumblebee Trick
The Grass Pink is a master of "deceptive pollination." The flower features a bright yellow, fuzzy structure at the top that looks exactly like a bundle of pollen-rich stamens to a hungry bumblebee. However, it’s a trap!
When a bee lands on those yellow hairs, the "lip" (labellum) is actually hinged. The weight of the bee causes the lip to slam downward, pinning the bee's back against the flower’s reproductive column. There is no nectar reward; the bee simply acts as a courier, picking up or dropping off pollen packets (pollinia) before flying away, slightly confused but unharmed.
Identification
The "Upside Down" Flower: In most orchids, the labellum (the "lip" petal) is at the bottom. In Calopogon, it is at the top, decorated with a brush of stunning yellow and orange hairs.
The Foliage: True to its name, it produces a single, long, grass-like leaf that emerges from the base of the plant. It is ribbed and can be easily overlooked until the flower spike appears.
The Stem: A slender, smooth green stalk that can reach 1–2 feet in height, bearing anywhere from 2 to 10 flowers that bloom in succession from the bottom up.
The Bloom Time: Look for these bright splashes of pink in the mid-summer heat, typically from late June through July.
