American basswood (Tilia americana) is a common deciduous tree in midwestern and eastern U.S. forests. This large native tree is one of the latest trees to flower in the forest, relying entirely upon insects to pollinate the flowers. Most deciduous canopy trees are wind-pollinated, flowering in early spring before the leaves emerge to ensure that their pollen is transported by wind. To attract pollinators, American basswood’s flowers are fragrant and offer both pollen and nectar to visiting insects. Large, showy cream-colored bracts persist on the tree as the flowers turn to fruit in late summer and provide interest well into fall.

Distinguishing traits. American basswood can have a single trunk or multiple trunks. When the main trunk is in decline in the wild, new lateral trunks will be produced. Nursery-grown stock almost always has a single trunk.

How to use it. American basswood can be used as a stand-alone shade tree, planted along the edge of a woodland or incorporated into a woodland opening in partial sun. It also is suitable as a residential street tree.

Planting notes. American basswood is a fairly fast-growing tree, which makes it suitable to use as a shade tree or as screening along the edge of a woodland.

Pollinator notes. American basswood flowers are fragrant and showy and attract a number of different flower-visiting insects, including beetles, flies, wasps, moths and bees. After opening, they offer pollen for a short period of time. Following this initial phase of the flower development, the flowers become receptive to pollen and, at the same time, increase nectar production.

They receive many visits in the evening from nocturnal moths, because nectar production often peaks in the late afternoon, providing an abundant supply in the evening hours.
