Rhododendron ferrugineum, commonly known as the rusty-leaved rhododendron, is a flowering plant native to the mountainous regions of Europe. It typically grows in rocky, alpine environments and can reach heights of about 1 to 2 meters. The plant is characterized by its leathery, dark green leaves that have a rusty-brown underside, giving it its name. The flowers of Rhododendron ferrugineum are usually pink to purple and bloom in clusters during late spring to early summer. This species is well-adapted to cold climates and is often found in areas with poor soil conditions, making it a resilient choice for alpine gardens and landscapes.
