Rhododendron buxifolium is a shrub or small tree from the high mountains of Mount Kinabalu in Borneo, growing between about 3,100 and 3,900 m. It is rarely grown outside its native range, and cultivation advice is limited, so it suits only growers who can mimic cool, humid, high-altitude conditions.

About

Rhododendron buxifolium is a species of rhododendron native to Borneo. It is a shrub or small tree, found only at high elevations on Mount Kinabalu in Malaysia's Sabah state.

It is a tree up to 10 m (33 ft) tall, and can grow to its full height in the subalpine forests and shrublands. In the Alpine zone closer to the summit, it grows as a stunted shrub among rocks. The species name buxifolium means 'box-leaved', because its small glossy leaves resemble those of boxwood (Buxus spp.).
