How has Vaccinium oxycoccus adapted to its surroundings?

The roots of the Vaccinium oxycoccus grow horizontally and are constantly being covered by the growth of Sphagnum. In order to be able to survive the Vaccinium oxycoccus must grow verticle shoots up away from the Sphagnum. These shoots contain leaves that aid in photosynthesis in the Vaccinium oxycoccus. (Jaquemart p. 386)

Water is a very important part of the life cycle of Vaccinium oxycoccus. The yield of the actually cranberry fruit is very dependent on the amount of flowers produced the year before. Low rain fall and low air temperatures drastically reduce the number of surviving flowers in a given year. Early in the year the flowers of the Vaccinium oxycoccus are able to go dormant in order to try and ride out early frosts and low rainfall. (Jaquemart p. 387)

Vaccinium oxycoccus has also been able to over come some nutritional shortages by a mutualistic relationship between it's roots and the fungus Hymenoscyphus ericae. These fungi help to detoxify the soil around the plant and help it gather nutrients. (Jaquemart p. 387)
