Tilia americana (Basswood, American Linden)


Michael's Opinion

A common tree found along rural hedgerows. It is relatively fast growing and produces softwood that is often used in high school shop projects. Of little use in the designed landscape, it can reach a height of 20 m. It is usually found as a multi-stemmed tree.
