Viburnum mongolicum

Viburnum mongolicum is a deciduous shrub in the Viburnaceae family. Its native range runs from southeastern Siberia to northern China. Records also place it in Mongolia and several Chinese provinces. These include Hebei, Henan, Shanxi, Shaanxi, Gansu, and Qinghai. It belongs to the temperate flora of this region. It is not native to Britain or Ireland.

The shrub reaches about 6.6 feet (2 metres) in height. It loses its leaves for winter. Flowers appear from April to June. Each flower has both male and female parts. Insects carry pollen between flowers, but the plant cannot fertilise itself. Fruit and fertile seed need pollen from a genetically distinct plant. That second plant must belong to the same species. Growing two plants therefore requires more than copies of one parent. The fruit can be eaten raw or cooked. The source gives it a low edible-use rating, however.

This species is easy to grow when its basic needs are met. It accepts sandy, loamy, and clay soils. It also tolerates mildly acid, neutral, and mildly alkaline conditions. Deep, rich loam offers its preferred growing medium. Keep the soil moist rather than choosing a dry site. Poor soil is also a poor match for this shrub. It grows in sun or partial shade. Shelter from early morning sun in spring is preferred. A sunny woodland edge or dappled shade suits its listed garden uses. Plants For A Future lists USDA zones 4–8.

Seed propagation can take patience, despite the plant's ease of cultivation. Sow ripe seed promptly in a cold frame. Germination may take more than 18 months. Fully developed seed collected before ripening may sprout the next spring. Stored seed needs two months of warmth, then three months of cold. Even after this treatment, germination can still take 18 months. Move seedlings into separate pots once large enough to handle. Grow them under glass or in a cold frame. Plant them out the following late spring or early summer. Early-summer softwood cuttings provide another route to new plants.

Plants For A Future reports no known hazards for this species. That statement does not establish safety for pets or every plant part. It lists no known medicinal or other uses. It also records no weed potential.
