Tilia chinensis aka Chinese Linden

Tilia chinensis, or Chinese lime, is a deciduous tree. It belongs to the mallow family, Malvaceae. Its native range runs from Tibet into central and east-central China. It grows in a temperate climate. Records place it in woods in western Sichuan. There, it grows at heights of 7,550–9,840 feet [2,300–3,000 metres]. It is not native to Britain or Ireland.

This spreading tree varies in size and form. The RHS describes trees reaching 46–66 feet [14–20 metres]. Its size guide gives a spread beyond 26 feet [8 metres]. It takes 20–50 years to reach maturity. Older trees have grey bark that flakes away. The green leaves are broad or rounded, with sharp teeth. Each leaf ends in a narrow point. The leaves turn golden yellow before falling in autumn. Clusters of pale green flowers appear in summer. These flowers have a scent.

Chinese lime needs room in parks or very large gardens. It can form the canopy of a woodland garden. The RHS also suggests it for wildlife gardens and bold planting schemes. Grow it in sun or partial shade, sheltered from cold winds. It needs moist soil that drains well. Chalk, clay, loam and sand all suit it. It accepts acid, neutral and alkaline soil. The RHS rates it H4 for UK hardiness. Plants For A Future lists USDA zones 4–8. These ratings use different climate scales.

Several pests may attack this tree. They include aphids, horse chestnut scale and caterpillars. Sawflies and gall mites may also cause trouble. Possible diseases include sooty mould, Phytophthora root rot and honey fungus. Seeds can be stratified outdoors in containers for spring propagation. Chip budding is another option, but rootstock choice needs care.

Plants For A Future lists young leaves as edible raw. The flowers can also be used to make tea. Ground fruit and flowers can form a chocolate-like paste. That paste spoils fast, which has limited its commercial use. The same source records medicinal use of flower tea. Reported uses include easing spasms, promoting sweating and aiding calm. These are records of use, not proof of treatment benefits. Inner bark supplies fibre for items such as sandals and nets. The source lists no known hazards, but this does not establish safety for every use.
