Linden (Tilia spp.)

Family: Tiliaceae

Flowering: June - Late July



The tree may reach up to 35 meters height. The alternate leaves are simple, toothed and asymmetrical. The flowers are hermaphroditic and aggregated into cymose inflorescence attached to a large ribbon-like bract. They are yellowish or whitish and highly fragrant.


The linden is often planted in parks and avenues. The most common species in Belgium are the large-leaved lime (Tilia platyphyllos), the small-leaved lime (Tilia cordata), and the silver lime (Tilia tomentosa).


The pollination is mediated by insects. Pollen quantities in the air are therefore never high. However, locally (in linden-lined avenues for instance) pollen counts may reach levels sufficiently high to cause symptoms to sensitized individuals.
