Viburnum corylifolium

Viburnum corylifolium is a deciduous shrub in the Viburnaceae family. Its native range runs from the Himalaya to central and southern China. Plants For A Future also records it in Assam, India. It grows in thickets in the Khasya hills. These sites lie at 3,940–5,905 feet [1,200–1,800 metres]. Kew lists its climate as temperate. The species is not native to Britain or Ireland.

The shrub reaches about 10 feet [3 metres] in height. It sheds its leaves rather than keeping them year-round. Its June flowers contain both male and female parts. Insects pollinate them, but a plant cannot fertilise itself. Fruit and fertile seed require a nearby, genetically distinct plant of the same species. The oval fruit measures about 0.03 feet [0.008 metres] long. Each fruit holds one large seed. The evidence gives no species-level details on bark or leaf shape.

This shrub suits a woodland garden edge or a site with dappled shade. It also grows in full sun where soil stays moist. Plants For A Future describes it as easy to grow. It favours deep, rich loam but accepts sand and clay. Poor soil and dry sites do not suit it. The source lists mildly acid, neutral, and mildly alkaline soils as suitable. It also warns that the plant dislikes chalky ground. Shelter from early spring morning sun is recommended. The listed USDA hardiness range is zones 5–9.

The fruit can be eaten raw or cooked. Plants For A Future gives its edible value a low score. The source reports no known hazards, but this does not establish safety for pets. It lists no known medicinal or other uses. The supplied evidence names no pests or diseases for this species. It also gives no mature width or growth rate. Its supported garden role is as a shrub for moist woodland edges.

Seed propagation can take patience. Fresh, ripe seed is best sown in a cold frame. Germination may take more than 18 months. Fully developed seed sown before ripening may sprout the next spring. Stored seed needs two months of warmth, then three months of cold. Even after that treatment, sprouting may take 18 months. Young plants can grow on in a cold frame or greenhouse. Softwood cuttings offer another method in early summer.
