Rhododendron keiskei is a species of flowering plant in the heath family Ericaceae, native to Honshu, Kyushu and Shikoku in Japan.
It is a low-growing, spreading evergreen shrub, reaching only 60 cm (24 in) tall by 1.85 m (6.1 ft) broad when mature. The leaves are elliptic in shape, and the pale yellow flowers, each with ten prominent stamens, are abundantly produced in spring.
The specific epithet keiskei honours the Japanese botanist Keisuke Ito (1803–1901).[1]
