Plant Parts
This plant, Rhododendron groenlandicum, is characterized by its distinctive leaves, which are thick, leathery, and evergreen in nature. These leaves are typically elliptical or oblong in shape and feature a dark green upper surface, while the undersides are often covered in a fine, felt-like layer of hairs that help the plant retain moisture in its harsh Arctic habitat. While various parts of many rhododendrons can contain toxic compounds, the structural integrity and specialized adaptation of these leaves allow the plant to survive in extreme subarctic environments.- Total parts
