Tilia amurensis aka Amur Lime

Tilia amurensis is known as Amur linden or Amur lime. This tree belongs to the mallow family, Malvaceae. Its native range spans the Russian Far East and Korea. Plants For A Future also lists northeastern China within its range. It grows in woods in North Korea. Chicago Botanic Garden describes its shape as upright. In gardens, it reaches 50–75 feet [15.24–22.86 metres] tall. Its spread can reach 50 feet [15.24 metres].

The green leaves range from broad ovals to rounded shapes. Each has a pointed tip and a heart-shaped base. Sharp teeth line the edges of the leaf blades. Leaves grow to about 2.5 inches long. Their undersides often have a pale, waxy cast. Young leaves have hairs where veins meet beneath the blade. Pale yellow flowers hang in clusters of three to twenty. They have a scent and attract butterflies. Chicago records bloom from May through June. Missouri Botanical Garden places flowering mainly in June. Small, egg-shaped to rounded nutlets ripen in late summer.

Grow this tree in full sun or partial shade. It prefers moist, fertile loam with good drainage. It also accepts a broad range of soil conditions. Average garden soil can support it when drainage is good. It tolerates drought, though moist soil suits it best. Missouri Botanical Garden rates its upkeep as low. Chicago lists it for USDA zones 3–7. Its tolerance of city conditions supports use along streets. It also serves as a lawn or shade tree. A single tree can form a focal point. It remains uncommon in gardens in the United States.

Serious pest and disease troubles are not usual. Leaf spots, powdery mildew, and canker can still occur. Verticillium wilt is uncommon but may kill the tree. Borers, scale insects, and leaf miners may attack it. Other pests include lace bugs, caterpillars, aphids, and Japanese beetles. Spider mites can cause trouble during hot, dry spells. These risks do not change its low upkeep rating.

Plants For A Future lists young leaves as edible raw. It describes them as food used during times of shortage. Ground fruit and flowers can make a chocolate-like paste. The paste breaks down fast, which limits its use. The same source records flower tea for traditional medicinal use. Reported uses include easing spasms, promoting sweat, and aiding calm. Its inner bark supplies fibre for sandals and other items. Plants For A Future reports no known hazards. That report does not establish safety for every use or pet.
