We took a drive out to Kananaskis yesterday to take a look... we didn't hike but only scaled up a roadside slope to check things out, bloom-wise, and were pleased to find a nice selection of foothills/prairie plants in bloom...
The brilliant blue of Penstemon nitidus on the clay slope was what caught my eye while driving...
Antennaria in abundance on the dry, south-facing hillside; patches here and there of Sedum lanceolatum (x2); Habenaria viridis (x2) at the forest edge;
In the lodgepole pine forest, Clematis occidentalis - some showing the usual 4 sepals, and one with 6... the same variability as one sees on cultivated plants, it seems!
Back out in the sun, Geum triflorum with Habenaria viridis; Polemonium pulcherrimum:
Could your orchid be a Corallorhiza sp.? When I was very young and didn't know any better, I dug one up in the woods of northern Minnesota to see the "root" structure. Very interesting indeed!
Good call, Rick. I think it's Corallorhiza trifida, pale coral-root. Thanks.
