RHH's photos with the keyword: 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.

Photographed along the Yellowhead Highway in British Columbia, this is one of the green-flowered Platantheras that are so difficult to identify, but this fits best though not perfectly the description of Platanthera huronensis, the Green Bog Orchis.

The green bog orchids are notoriously difficult to identify and intergrade with each other, but this fits the description of Platanthera huronensis, the Green Bog Orchis, quite well. These can grow quite tall, up to three feet and can have around eighty flowers per spike. The individual flowers, however, are quite small and nondescript as is evident from the photo. This was photographed along the highway in Mount Robson Provincial Park in British Columbia.
