Piperia unalascensis in the Canadian Rockies
Traveling along the Yellowhead Highway in British Columbia and Alberta we found this common species of native orchid in various locations, often growing along with other orchids. In one location it was growing with Platanthera dilatata, the Bog Candle, and in another with Platanthera huronensis, the Green Bog Orchis, and Coeloglossum viride, the Long-bracted Green Orchis.
Though it often grows in large clumps the plants we saw were usually just single spikes. They are easily identified, however, by their short spurt, many flowers, yellow-green color and small lip. They were almost always in open sunny locations and areas that were quite wet. The plant is found all across North America and so it was no surprise to find it here also.
