Green Bog Orchis

These were photographed along the highway in Thompson Pass between Glennallen and Valdez. We found three different orchids in the place where we stopped, this the tallest and the one that caught our attention as we drove by. Its Latin name is Platanthera huronensis and it is a common orchid across the USA and Canada. This species can be as tall as three feet (90-100 cm) but these were 18 inches (45 cm) or less.
