They are asymmetrical and have a heart shaped outline. The underside of the leaf is hairy with tufts of denser hairs along the leaf vein axis. It’s hermaphrodite flowers are fragrant and are produced in clusters of four to ten in early summer with a leafy yellow green subtending bract.

Tilia x europaeacommonly known as the Common Lime or the Linden, is a naturally occurring hybrid between Tilia cordata and the Tilia platyphyllosTilia x europaea is synonymous with Tilia x vulgaris. It naturally occurs in the wild in Europe at various locations. It is also listed as Brittan’s tallest broad leafed tree reaching a height of 40m.

The etymological root of the binomial name Tilia is the old Latin name for the Lime tree. Europaea is derived from the Latin meaning of or from Europe.

The landscape architect may find Tilia x europaea useful as a large parkland tree. Although often used as an avenue tree it is not the best suited Lime for this purpose  as it will require a lot a pruning due to its eventual size, it produces sprouts from it’s base and due to the large populations of aphids this tree harbors, honeydew below the canopy can be a problem. It can tolerate strong winds but not maritime conditions.

Ecologically, Tilia x europaea provides a valuable source of food for aphids who feed on it’s leaves. The sweet smelling flowers of this tree attract bee’s which enjoy the tree’s abundant nectar. This tree also is great at attracting moths such as the green caterpillar or lime hawk moth which feed on the tree’s leaves.

Tilia x europaea is tolerant of most soils from sandy to clay soils, as long as it is well drained soil. It can also grow in nutritionally poor soils. It requires a soil pH of acid to alkali.

The Royal Horticultural Society has given Tilia x europaea ‘Wratislaviensis’ their prestigious Award of Garden Merit in 1993.

Tilia x europaea requires little maintenance and can tolerate heavy pruning when necessary. This tree is suitable for pollarding. If the specimen is being pollarded it should be carried out every year or every other year and should be carried out in late winter or early spring.
