Rhododendron makinoi, commonly known as Makino rhododendron, is an evergreen shrub native to the mountainous regions of Japan, particularly on Honshu, Shikoku, and Kyushu islands. It thrives in cool, moist conditions found in subalpine forests and forest margins. This species typically grows up to 8.2 feet (2.5 meters) tall and wide, featuring distinctive woolly young shoots and long, narrow, curved leaves that are a striking green on top and heavily felted brown on the underside. In late spring to early summer, Makino rhododendron produces trusses of deep pink buds that open to pale pink, bell-shaped flowers with red spots inside, which are quite showy and attract pollinators.

The Makino rhododendron is valued for its attractive foliage and beautiful flowers, making it a favored choice for woodland gardens, shrub borders, and as a specimen plant in areas with cool, moist climates. It has been awarded the Royal Horticultural Society’s Award of Garden Merit, indicating its excellence for garden use. Cultivation requires a sheltered location with dappled shade, acidic soil enriched with leaf mold, and consistent moisture without waterlogging. It is hardy down to 5°F (-15°C), but protection from harsh winter winds is advisable to prevent damage to the foliage. While generally disease-resistant, it can be susceptible to pests such as vine weevil and diseases like powdery mildew if conditions are not ideal.CC BY-SA 4.0
