Orchid Collection from Cranberry Glades. From May through September, the high elevation sphagnum bogs and spruce-northern hardwood forests of the Allegheny Mountains produce a steady stream of terrestrial orchids. Prime time orchid season around Cranberry Glades is mid-June through early July, when the showiest orchids hit their peak. As a note, many of these orchids are wetlands-dependent and are endangered or threatened throughout much of their range due to habitat loss.
From top: grass pink (Calopogon tuberosus), unusual among orchids in that its lip is at the top of the flower, making it appear upside down; rose pogonia (Pogonia ophioglossoides), also known as snakemouth orchid due to its elaborate lower lip with pink and yellow-tinged teeth; downy rattlesnake plantain (Goodyera pubescens), a shade-tolerant woodland orchid that was just beginning to send up its flowering stalks; Round-leaved rein orchid (Platanthera orbiculata), or dinner-plate orchid, another terrestrial woodland orchid; large purple-fringed orchid (Platanthera grandiflora), or greater purple-fringed bog orchid, a tall, showy wetlands lover with a special fondness for damp seeps that get full or dappled sunlight; northern tubercled bog orchid (Platanthera flava), or pale green orchid, whose tiny flowers are distinguished by conspicuous bumps (tubercles) on their lower lips; and lily-leaved twayblade (Liparis liliifolia), a very unusual orchid whose flowers mimic the color of carrion to lure flies, which pollinate them.
