Tilia americana var. heterophylla Tilia americana

Common Name(s):

  • Beetree Linden
  • White Basswood

Tilia americana, commonly called American basswood or American linden, is a medium to large deciduous tree which typically grows to 50-80’ (infrequently to over 100’) tall with an ovate-rounded crown. It is native to a variety of habitats from Quebec to the southeastern corner of Manitoba and far eastern North Dakota south to Oklahoma, Tennessee and North Carolina, with concentrations in forested areas of the Appalachian Mountains and along the Ohio River Valley to Missouri. Trees are found in both dry upland areas as well as moist, low woods.  The bark is smooth and gray/green in young trees.  As the tree ages, the bark turns gray/brown and develops shallow furrows and fibrous flat top ridges.

The common name of basswood is derived from bastwood, in reference to the tough inner bark (bast) which has been used to make rope and mats. Trees are commercially harvested, particularly in the Great Lakes region, for their light wood which is used to make such items as furniture, shipping crates, boxes, and veneer. Common name of linden plus the family name of Linneaus (famous Swedish botanist Carl Linnaeus was ennobled as Carl von Linne) both derive from lind which is the Swedish word for a linden tree.

When a tree is in full bloom, bees often visit in such abundant numbers that humming can be heard many feet from the tree.   It does not tolerate air pollution or urban condtions. When injured the tree produces a sweet mucilaginous sap.

This tree is noted for its (a) cymes of fragrant, pale yellow, late spring flowers, (b) small nutlets which follow the flowers and ripen by late summer, (c) mucilaginous sap, (d) noticeable winter buds, and (e) large ovate dark green leaves (to 6” long) with acuminate tips, serrate margins, often silvery undersides and uneven cordate bases.
