Photo 3757-04: Sugar-frosted leaves of the bog blueberry or bog...north from St.Petersburg, Russia

Sugar-frosted leaves of the bog blueberry or bog bilberry (Vaccinium uliginosum), locally known in Russia as golubika. The ice crystals have nucleated along the leaf margins, outlining each small oval leaf in white. This creates a striking contrast with the deep crimson tissue. The deep red pigmentation is due to anthocyanins.This is a classic sign of the "pre-winter" season (predzimye) in the taiga ecosystem. Kannelyarvi, north from St.Petersburg, Russia
