D. anglica grows on the wettest part of the bog directly on the peat, while D. rotundifolia grows on the Sphagnum moss on the outskirts. (There may be D. x obovata as well, but I didn't know to look back in july.)
No plants had started growing yet. I don't know whether that's normal or not, but the winter has been longer and colder than usual here in Oslo as well. Night temperatures still occasionally drop below zero degrees C.
