Pyrola chlorantha — green-flowered shinleaf

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Research shows that to acquire carbon, green-flowered shinleaf relies not only on photosynthesis like other flowering plants, but also gets substantial carbon from root fungi which in turn get the carbon from a tree. This mixed system of nutrient acquisition is called mixotrophy.
