Tilia americana L.
American basswood, American linden, Lime tree, Bee tree
Tiliaceae (Linden Family)
USDA Symbol: tiam
American basswood is a stately, wide-spreading tree, 60-80 ft. tall, occasionally growing taller. Conical in its younger form, the crown becomes rounded with age. Broadly oval leaves sometimes change to yellow in fall but often turn brown and become somewhat unsightly. This deciduous tree tends to sprout at the base, producing a clump of tall trees around what was the original tree. Flowers are inconspicuous but fragrant. Large tree with long trunk and a dense crown of many small, often drooping branches and large leaves; frequently has two or more trunks, and sprouts in a circle from a stump.
American Basswood, the northernmost basswood species, is a handsome shade and street tree. When flowering, the trees are full of bees, hence the name Bee-tree; this species is favored by bees over others and produces a strongly flavored honey. The soft, light wood is especially useful for making food boxes, yardsticks, furniture, and pulpwood. Indians made ropes and woven mats from the tough fibrous inner bark.

Conditions Comments: American lindens are used as specimen plants because of their attractive form, leaves and fragrant flowers. The dense shade they create limits ground cover options. The species is susceptible to a variety of disease and insect problems. Foliage-feeding insects are a particular nuisance. Trees grow at a medium to fast rate.
BenefitUse Medicinal: A hot bath with basswood flowers, followed by a cup of linden-flower tea, is said to soothe cold symptoms and enhance sleep. The flowers are also used in beauty products. (Kershaw)
Use Other: Native peoples and settlers soaked the inner bark in water to separate its tough fibres, which were then used to make ropes, nets, mats, shoes, clothing and thread. Some tribes carved ritual masks on living trees, then split the masks away to hollow and dry the inside. If the tree survived, the mask was believed to have supernatural powers. (Kershaw)

PropagationDescription: Untreated seeds germinate in 2-3 years. Seeds germinate most easily if fruits are collected as they first trun slightly brown and are planted immediately. Mechanical or chemical pretreatment of the hard pericarp and seed coat hastens germination.
Seed Collection: Seeds germinate most easily if fruits are collected as they first turn slightly brown. For storage, dry seeds and store at room temperature up to two years.
Seed Treatment: Scarify mechanically or soak in concentrated sulfuric acid and moist chill for 3 months.
Commercially Avail: yes
