Plant Profile: Tilia americana var. heterophylla

The White Basswood is a sizable native deciduous tree characterized by its rounded, ovate crown, making it an excellent choice for providing dense shade. Belonging to the Malvaceae family, it was once classified as a distinct species but is now recognized as a variety of the American Linden. The White Basswood closely resembles the American Linden, with the notable difference being the dense hairs on the underside of its leaves, which give them a white appearance. This tree typically reaches heights between 50 and 120 feet and thrives in ravines, lush hardwood forests, and along waterways.

Commonly referred to as Beetree Linden, Linden Tree, or Mountain Basswood, this species includes a cultivar named 'Continental Appeal,' which features a narrow oval shape, growing up to 50 feet tall and 30 feet wide.

The natural habitat of the White Basswood spans from southern Pennsylvania to Maryland, extending along the Ohio River through Missouri, Mississippi, and North Carolina.

The genus name, Tilia, is derived from Latin, meaning Linden or Lime Tree, and traces its roots to the Greek word "ptelea," which translates to 'Elm tree,' or "tillai," meaning 'Black Poplar.' This name reflects the tree's broad leaves. The species name, heterophylla, combines two Latin terms: "hetero," meaning "different," and "phylum," meaning "leaves," highlighting the tree's distinctive foliage. The common name, Basswood, originates from "bastwood," referencing the inner bark known as bast.

The White Basswood flourishes in full sun to partial shade and prefers loamy, moist, well-drained soils. It is sensitive to urban environments and air pollution but demonstrates drought resistance once established.

This species often produces stump sprouts that can be transplanted, and it can also be propagated from seeds.

The leaves of the White Basswood can grow up to 6 inches long and wide, featuring a dark green upper surface and silvery-white undersides. In autumn, the foliage transitions to pale green or pale yellow. The tree produces fragrant, creamy-colored flowers that cluster together, with each cluster containing 10 to 25 blossoms. The resulting fruit is a small, rounded woody nutlet.

Pollinators such as bees are attracted to the nectar of the flowers, while deer enjoy the leaves. Cavity-nesting birds, including wood ducks and woodpeckers, along with various small mammals, find refuge in the tree's softwood. Rabbits tend to feed on the seedlings and young saplings, while mice, squirrels, and chipmunks are drawn to the seeds.

With its striking foliage and fragrant flowers, the White Basswood serves well as a shade or specimen tree in residential areas or parks.
