Summary

Rhododendron brachycarpum, commonly known as the Daurian Rhododendron, is an evergreen shrub native to alpine regions, subalpine forests, and mountain slopes in Japan and Korea. It typically grows to a height of 3-15 feet (1-5 meters) and a similar width, with a dense, rounded form. The leaves are thick, leathery, and dark green, providing year-round interest. From late spring to early summer, it produces clusters of bell-shaped flowers that vary in color from light red to white, which are quite showy and attract pollinators such as bees and butterflies.

The Daurian Rhododendron is valued for its cold hardiness, evergreen foliage, and attractive flowers. It is used in garden landscapes as a specimen plant, in shrub borders, and in woodland gardens. This species thrives in acidic, well-drained soils and prefers part shade, though it can tolerate full sun in cooler climates. It requires consistent moisture but does not do well in waterlogged conditions. While generally disease-resistant, it can be susceptible to root rot if drainage is poor. It is also important to protect this rhododendron from harsh winter winds. Cultivars such as ’Capistrano’ and ’Yaku Prince’ offer variations in flower color and plant size for gardeners seeking diversity.CC BY-SA 4.0
