It looks like the European Coeloglossum is a bit showier- some dark or light but less green, and more compact inflorescences.Yes, we do have Calypso and Amerorchis - though I haven't seen it since I've been back, the patch where it used to grow was logged, and it's one of those things you'd be unlikely to see out of flower.. also Corallorhiza maculata

Thanks for the picture and mention of Coeloglossom viride! For whatever reason, I have not been aware of this plant.... but when I checked my copy of "The Orchids of the Ottawa District", there it was, and listed for exactly my area. In fact, one of the main collections of this plant is listed as from only about 10 km away. I will be looking hard for this one this summer! It apparently likes 'semi-mature to mature deciduous woods.... usually rocky....' which is just what I have.
BTW, it has been down to -28C the last couple of nights, but snow cover is good this year.
Gardening on a wooded rocky ridge in the Ottawa Valley, Canada. Cold winters (-30C) and hot, humid summers. Nuts about native plants, ferns, pottery, my family, and Border Collies.
Definitely no rocks around here for Coeloglossum (I'll need to look more closely this year to see if it's there, but I suspect so)- for surface rocks you have to get into the foothills!
You are welcome, Lis!Coeloglossum viride is rather common both at the coast and in the lower alpine region here although I have only seen the alpine forms. It is not always rocky where it grows as it can be rather boggy too but not very acidic.
All these are growing on rocky outcroppings but with plenty of alkaline water seeping in the cracks. The first picture shows the companion plants.
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Thanks! Good pictures like that really help develop one's 'search image'. Once you have a good search image in your head, it is amazing how much more likely you are to spot them in the field.
Wish it were spring....
I don't know about Ontario, Lis, but in the west it seems our Coeloglossum looks little like Trond's.Here is a plant that I think may be it, I'm going to have to look more closely this year, but note the long bracts which I think are characteristic of the species.. I need to reqad through the keys some more to see if there is any other important character I'm missing...In any case, images I've seen online of North American examples look more like my plant and not like Trond's at all..My feeling is that the more or less extended bracts may be a matter of the maturity of the inflorescence, but I could well be wrong... I will need to mark some plants this year and keep closer track! Whatever these are, there are tons of them here ;)
Cohan, the last plant you show (marked Platanthera) looks like a Coeloglossum. The others do look like Platanthera! Genetically Coeloglossum is close to Dactylorhiza and may be sunk into it.
Thanks for the input, Trond, I will need to look at them more closely this year- although I regularly photograph them, being not very showy and super common they don't attract much close attention- I've started to accumulate photos that focus on things like bracts and leaf characters.All those (bog orchids) here are very similar- more or less lanceolate leaves, green to greenish white flowers- we have no species with ovate leaves or white flowers.. All the photos were labelled Platanthera originally, since until this discussion I had not even noticed that Coeloglossum was even in the running...lolChecking through my books now, I see why I was not thinking of Coeloglossum: two of my books list it as a synonym for Habenaria, even Platanthera, and the only one that uses that as the main name (also gives Habenaria as synonym) shows a very leafy plant that doesn't look like those around here...
I think the other Platanthera in my photos above could be P hyperborea..
interesting rather than exciting a North American native
Similar to the natives here, Tony, though, I think, a more expansive inflorescence than some.
