Basswood’s beautiful, large green leaves create a dense shade, and its fragrant flowers yield nutritious nectar that attracts pollinators. The tree is tolerant of many soils and grows fast, making it a popular native shade tree. It is also known as American Linden and Beetree, and it can be used as a shade tree, a specimen tree, or to naturalize an area with great value to wildlife.

Suggested Uses: Basswood can be used as a shade tree in the landscape as well as a specimen tree due to its aromatic flowers and large leaves. Use it to naturalize an area as it has great value as a native tree and is very useful to wildlife.
Wildlife value and ecological benefits
Wildlife Value: Many species find Basswood delicious. The flowers attract honeybees, bumblebees, and flies. Honeybees prioritize all flowers based on nutritional value and availability and they prefer the Basswood flower over any other flower that blooms during the same time, resulting in crops of honey made purely from Basswood nectar. This is a big honey tree for beekeepers. The tree supports songbirds that eat the seeds, and deer, rabbits, mice, squirrels, and other mammals feed on stems, leaves, and seeds. The hollow trunk after death provides dens and shelter for wood ducks, pileated woodpeckers, and other wildlife.
Maintenance and care during establishment
Maintenance Tips: Mulch around the base to keep soil moist. Basswood dislikes dry soil and benefits from supplemental water during drought. Trim inward-growing branches during dormancy. Wrap the trunk or cage the lower part of the tree to prevent rodents and deer from chewing on bark and stems.
Pests and problems
Pests/Problems: Linden borers can damage bases, especially in very young or very old trees. Linden Looper, Basswood Leafminer, Japanese Beetles, cankerworms, Whitemarked Tussock Moth, and Gypsy Moth can cause defoliation. Mice and voles may girdle young trees; use a cage for protection. Pesticide cautions: Systemic pesticides should not be used on lindens; insects will move through their life cycles and leaves can recover in spring. The tree supports wildlife and aesthetic insect activity is common but usually not fatal. Diseases can include Anthracnose, black mold, and leaf spot, which are primarily aesthetic. Exposed wood from pruning can lead to canker and yellow cap fungi; prune during dormancy to help prevent this.
Practical uses and additional notes
Leaf lore and uses: The largest known Tilia americana is 102 feet tall with an 85.5-foot spread. Medicinal uses include bark tea for burns, heartburn, colds, and migraines; leaf tea for burns, swelling, headaches, and indigestion. Soft wood is used for carving and furniture; inner bark fibers for rope, basket weaving, and mats. Flowers can be used to make tea. Young leaves can be eaten raw or cooked, and the sap can be boiled into syrup. However, excessive consumption of flower tea may cause heart damage.
Installation & care specifics: Find the root flare, root prune as needed, structurally prune as needed, remove stakes and tags, plant so the root flare is visible, water the root ball during installation, and apply hardwood mulch 2 inches from the trunk, 2 to 3 inches deep, with a radius of at least 2 feet. The tree is commonly grown in specific sizes and availability may be restricted to wholesale customers.
Planting and care steps for seedlings
Planting: Choose a site with full sun to partial shade and well-drained soil. Locate the root flare at or just above soil grade when planting. Water consistently during establishment and mulch to maintain moisture without smothering the base. Prune only as needed to shape and remove inward-growing branches during dormancy. Consider deer and rodent protection for the vulnerable lower trunk during the first years.
Ongoing care: Basswood tolerates a range of soils but dislikes prolonged dry conditions. Regular watering during dry spells helps young trees establish. Monitor for pests and diseases; address issues promptly but refrain from systemic pesticides that can harm wildlife. If pests become problematic, physical barriers and cultural controls are preferred.
