|Comments||"Basswood is one of our most widely adapted, common and widespread trees, equally at home as a multi-stemmed runt on the Escarpment face and Pelee Island alvars or a stately, long-trunked patrician in our richest woodlands" (Waldron).
Supports many species as home or food, without being pests.
"In mixed stands with other broadleaf trees — usually outgrowing them" (Farrar).
Flowers and fruit have a uniquely Tilia look; a small long-stalked cluster joined to a distinctive, long, narrow, leaf-like bract. Flowers attract a large number of insect pollinators. Basswood honey is delicous.
Though a strong tree, the basswood adult size limits its application in smaller urban settings.
