Pileostegia viburnoides (climbing hydrangea) is a species of flowering plant in the family Hydrangeaceae, native to India and eastern Asia. It is a slow-growing, self-clinging, evergreen climber eventually growing to 6 m (20 ft) in length, with long narrow leaves and dense panicles of creamy white flowers in late summer. The specific epithet viburnoides means "like a viburnum", though viburnums belong to a different family of plants. The species is valued in cultivation for its ability to clothe east- or north-facing surfaces, which can be problematic due to low light levels.
