Scientific name: Arnica angustifolia

The buds of Arnica angustifolia demonstrate a couple of strategies that Arctic plants use to facilitate growth in their harsh climate. Before they open, dark hairy phyllaries cover the buds. The dark colour attracts the heat of the sun and the hairs trap that heat. These strategies help to warm the plant and encourage growth, allowing it to bloom successfully despite the cool temperature of the air. In some native cultures, arnica is used to help heal bruises and wounds. Part of the leaf is crushed then placed on top of the bruised or wounded area. source
