June is the most appropriate month to learn to distinct large-leaf linden from little-leaf linden. These are two different tree species and not perhaps a female and a male tree.
The leaves of large-leaf linden are distinctively larger. If we take a look at the lower side, we can see bouquets of white hairs between the veins. In the case of little-leaf linden, these hairs are brown. The attention should be paid to flowers too: in the case of large-leaf linden, there are three flowers in one inflorescence. In the case of little-leaf linden, there are 5-15 flowers above the bract. In the case of large-leaf linden, inflorescences are pending. In the case of little-leaf linden, they protrude behind the leaves in all directions. The species differ also in the time of bloom: large-leaf linden begins to bloom a week or two before little-leaf linden does.
In autumn, we can break the fruit of little-leaf linden. In the case of large-leaf linden, this is not possible, because their peel is too woody. A village tree, typical for the villages of Slovenian (and also German) landscapes, is usually large-leaf linden. It develops wider treetop and lives longer than little-leaf linden: it can live up to 1000 years. In the contrast with the large-leaf linden, we find the little-leaf linden in the forest. It is relatively rare but appreciated forest tree. Good-smelling flowers of both species are picked for medicinal teas. Both species are valued by beekeepers. Large-leaf linden and little-leaf linden are autochthonous species in Slovenia.
