}}Tilia tomentosa, known as silver linden in the US[1] and silver lime in the UK, is a species of flowering plant in the family Malvaceae, native to southeastern Europe and southwestern Asia, from Hungary and the Balkans east to western Turkey, occurring at moderate altitudes.[2][3] DescriptionTilia tomentosa is a deciduous tree growing to {{convert|20|-|35|m|ft|0|abbr=on}} tall, with a trunk up to {{convert|2|m|ft|0|abbr=on}} in diameter. The leaves are alternately arranged, rounded to triangular-ovate, 4–13 cm long and broad with a 2.5–4 cm petiole, green and mostly hairless above, densely white tomentose with white hairs below, and with a coarsely toothed margin. The flowers are pale yellow, hermaphrodite, produced in cymes of three to ten in mid to late summer with a pale green subtending leafy bract; they have a strong scent and are pollinated by honeybees. The fruit is a dry nut-like drupe 8–10 mm long, downy, and slightly ribbed.[2][4]Cultivation and usesIt is widely grown as an ornamental tree throughout Europe. The cultivar 'Brabant' has a strong central stem and a symmetrical conic crown. The cultivar 'Petiolaris' (pendent or weeping silver lime) differs in longer leaf petioles 4–8 cm long and drooping leaves; it is of unknown origin and usually sterile, and may be a hybrid with another Tilia species.[2][4] It is very tolerant of urban pollution, soil compaction, heat, and drought, and would be a good street tree in urban areas, apart from the problems it causes to bees.[2][5] In cultivation in the United Kingdom, T. tomentosa 'Petiolaris' has gained the Royal Horticultural Society's Award of Garden Merit.[6][7] An infusion made from the flowers of T. tomentosa is antispasmodic, diaphoretic and sedative.[8] This may be attributable to the presence of pharmacologically active ligands of benzodiazepine receptor [9] A widespread belief is that the nectar of this species contains mannose, which can be toxic to some bees. This is incorrect; the sight of numerous comatose bees found on the ground at flowering time is rather a result of the paucity of nectar sources in late summer in urban areas.[10] This species, while fragrant in spring, drops buds and pollen during the spring and fall. It is not a good sidewalk tree for that reason, requiring frequent streetcleaning. Notable treesEminescu's Linden Tree ({{lang-ro|Teiul lui Eminescu}}) is a 500-year-old silver lime (Tilia tomentosa Moench) situated in the Copou Public Garden, Iași, Romania. Mihai Eminescu reportedly wrote some of his best works underneath this lime, rendering the tree one of Romania's most important natural monuments and an Iași landmark.[11]References{{Commons|Tilia tomentosa}}1. ^{{PLANTS|id=TITO|taxon=Tilia tomentosa|accessdate=10 December 2015}} 2. ^1 2 3 Rushforth, K.
