Is that ice on the ground where the plants are growing? Are these photos current or were they taken at another time of year? I'm not sure what the plant is but it's quite interesting. My first thought was flower buds and then when I enlarged the photos, I thought possibly seedpods of some sort but it's difficult to tell.
Is it possible to post a photo showing the plants from a little distance? Are there any leaves present on any of them? Hopefully someone will recognize it but additional photos may help in identification.
