I saw these about a week ago near a lake in SE British Columbia. I see nothing in my ID book which helps me identify these. Sorry for a lack of footage of leaves... http://youtu.be/--aGZ8yUoL0 Thanks for any help!
It worked for me too, but here's a different link to the same 32 second video. There are essentially three views in the video. You can go to 10 sec, 20 sec, and 30 sec.
No, I used to see many of those out where I worked - I would've recognized those. But it appears you are close... I was told today that they are prairie crocus (a. patens) - which I also would of thought I recognized... but I had never observed them past their initial purple, fuzzy stage. I didn't recognize them at this stage! Thank you for the reply.
