Tilia tomentosa, known as silver linden in the US[2] and silver lime in the UK, is a species of flowering plant in the family Malvaceae, native to southeastern Europe and southwestern Asia, from Romania and the Balkans east to western Turkey, occurring at moderate altitudes.

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.

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.

[11] The evidence against a toxin in the nectar being responsible for mass bee deaths under Tilia trees is supported further by Koch and Stevenson (2017) who also suggest that the presence of caffeine in linden nectar may mean that linden trees can chemically deceive foraging bees to make sub-optimal foraging decisions, in some cases leading to their starvation.

Mihai Eminescu reportedly wrote some of his best works underneath this silver lime, rendering the tree one of Romania's most important natural monuments and an Iași landmark.
