Mountain avens are small, hardy plants belonging to the genus Dryas. They typically grow in rocky, alpine environments and are known for their ability to thrive in harsh conditions, such as cold temperatures and poor soil. The leaves are often leathery and evergreen, providing resilience against the elements. These plants produce attractive, white or yellow flowers that bloom in the spring and summer. Mountain avens play a crucial role in their ecosystems by stabilizing soil and providing habitat for various insects and wildlife. They are also important indicators of environmental health in mountainous regions.
