Tilia cordata 'Glenleven' - 'Glenleven' Linden
Family - Tiliaceae
Size - 40 to 50 feet in height. Spread is about 1/2 the height. Pyramidal in youth, pyramidal to rounded with age. Medium rate of growth, at least in the South.
Foliage - Alternate, simple. Sharply serrated, cordate. Dark, glossy green in summer, Fall color is yellow-green at best. Not much Fall color to speak of.

Bark - Gray-brown, ridged and furrowed when older.
Pests and Diseases - Japanese Beetles absolutely love the Tilias, in particularly the species, cordata, which is the Littleleaf Linden. I've yet to see the American Lindens (species americana) get hit by Jap. Beetles, but the Littleleaf species and cultivars can be decimated in just a few days. Don't ask me, why do some people love seafood and some don't?? Bark splitting can be a real problem on the genus Tilia, also. There are several American and Littleleaf Lindens on campus and every one have a frost crack that has degenerated in to a large splitting cavity on the southwest side.
Landscape Use - Can be a very nice shade tree for the home or commercial site. Some protection such as a seasonal wrapping for the first few years needs to be considered for splitting as it really affects the long term health of the tree. Situating the tree in to a microclimate where it isn't as exposed may possibly help this problem, also. Is used in planters and quite extensively as a street tree, particularly further north. Prefers moist, well drained soils, pH adaptable, air pollution tolerant. The Europeans use the species as a hedge quite a bit.
