Littleleaf Linden

Arbor walk #42, Treekeeper ID #4386

The Littleleaf Linden is uniquely adept at withstanding polluted environments, and is therefore a great shade tree for urban settings. It is a native to Europe and exists in the wild only in protected pockets of land, where it provides ecological benefits for moths and pollinators. However, it is prone to attack by Japanese beetles. The ‘PNI 6025’ cultivar grows to only about 50 feet, shorter than its species.
