The Little-leaf Linden was introduced from Europe and is widely used as a street tree because of its attractive dark green foliage and pyramidal shape. Linden trees are called lime trees by the British because the wood of the tree is less porous than other wood and was used to build furnishings for the cabins of ships to store limes and other citrus.6 Little-leaf Lindens have heart-shaped leaves and typically grow to a height of 50 to 70 feet. Linden trees are a favorite for honeybees. The flowers produce large amounts of nectar at a crucial time early in the season when the hive is raising the brood and many summer flowers have not yet bloomed. When the trees are in full bloom in June, bees visiting for the nectar come in such large quantities that buzzing can be heard from a few feet away from the tree. In German meaning “under the linden trees,” Unter den Linden is a famed boulevard in Berlin known for its many historic and cultural buildings and the linden trees planted to line the street.
