I dont know if the bluberry is natural, but it is so on so many places quite far from each other that maybe it really is. These forests are lower forests and didnt know there might be blueberry at all. I have discovered these walking away from the trails. I think that its too low for them to give a proper fruit. But it is beautiful, just blueberry and moss. Green floor. The deers come to eat the fruit constantly so I have never found a fruit to eat. In the autumn, when there is no more green, they come to eat the leaves of the blueberry, so the plants are so low, that it seems to be a carpet. Then need to grow from zero in the spring.
