Litsea cubeba aka Mountain Pepper

Litsea cubeba also goes by the name mountain pepper. It belongs to Lauraceae, the laurel family. Its native range runs from Nepal to southern Japan and western Malesia. It grows across China and much of Southeast Asia. Wild plants grow on sunny slopes and in thickets. They also grow in open woods, beside roads and near water. They grow at a wide range of heights above sea level.

This shrub or small tree grows fast. It has a short, straight trunk. Garden sources give heights of about 23–26 feet [7–8 metres]. A wider botanic account records heights of 49 feet [15 metres]. Plants may shed their leaves or stay green year-round. All parts have a lemon scent. This helps explain their use in foods and essential oils. The plant suits a woodland garden's sunny edge.

Plants For A Future gives March to April for bloom time. Insects move pollen between the flowers. Seeds ripen from August to September. Most plants bear either male or female flowers, not both. Some forms have flowers with working parts of both sexes. Grow plants of both sexes if you need seeds. Plants grown from cuttings may fruit within two to three years. The sources do not agree on whether plants can use their own pollen to set seed.

Plants For A Future lists sun or light shade as suitable. It lists moist soils of sand, loam, or clay. It gives a pH range from mildly acid to mildly alkaline. It also gives USDA zones 10–12. Yet it says hardiness in Britain is not certain. It suggests the plant might suit mild sites in Britain. This view rests on its native range, not proven garden trials. The sources give few details on how to grow it.

People eat the flowers or use them to flavour tea. They eat the fruit as a side vegetable or use it in place of pepper. Cooks also use the roots, bark, and leaves for flavour. Folk medicine uses several parts, but these reports do not prove health benefits. Growers raise the plant to make essential oil for sale. The wood provides timber. Plants give shade and shelter to tea crops on plantations. This pioneer tree also helps restore damaged woods. The sources report no known hazards. This does not mean they confirm that every use is safe. They give no specific account of pests or diseases.
