Tilia americana, commonly known as American basswood, American linden, or simply basswood, is a species of deciduous tree native to eastern North America.
American basswood typically grows to a height of 18-37 meters (60-120 feet) and has a rounded or pyramidal crown. The bark is grayish-brown and deeply furrowed, becoming more rugged with age.
The leaves of Tilia americana are alternate, simple, and broadly ovate with serrated margins. They are dark green on the upper surface and lighter green underneath. In the fall, the leaves turn yellow before dropping from the tree.
During late spring to early summer, American basswood produces small, fragrant, pale yellow flowers arranged in drooping clusters. These flowers are attractive to bees and other pollinators and produce abundant nectar, making basswood honey highly prized. The flowers are followed by small, round, nut-like fruits.
American basswood prefers moist, well-drained soils and can tolerate a range of soil types, including clay and loam. It thrives in full sun to partial shade and is relatively tolerant of urban pollution.
The wood of Tilia americana is lightweight, soft, and easily worked, making it valuable for carving, furniture making, and musical instrument construction.
