Rhododendron ferrugineum, commonly known as Alpenrose, is an evergreen shrub that typically grows up to 5 feet tall and wide. It is native to the mountainous regions of Europe, including the Alps, Pyrenees, Jura, and northern Apennines, where it thrives in subalpine and alpine zones. The Alpenrose prefers moist, acidic, siliceous soils and is often found in coniferous forests and shrubby areas, contributing to the unique ecology of these high-altitude habitats.

The Alpenrose is notable for its leathery, dark green leaves with rust-brown spots on the undersides and its clusters of showy, bell-shaped, pinkish-red flowers that bloom in late spring to early summer. The flowers are particularly attractive to pollinators such as bees. In cultivation, it is valued for its hardiness, evergreen foliage, and vibrant floral display. It is used in rock gardens, as foundation plantings, and in borders, especially in regions with cooler summer temperatures. Gardeners should provide Alpenrose with well-drained, acidic soil and ensure it receives regular moisture, especially during dry periods. It prefers part shade to full sun, with protection from harsh afternoon sun in warmer climates. While generally low-maintenance, it can be susceptible to pests such as vine weevils and diseases like root rot if conditions are too wet. It is also moderately toxic if ingested, so caution should be exercised where pets or children may have access.CC BY-SA 4.0
