This is a high maintenance tree that will require regular care and upkeep, and usually looks its best without pruning, although it will tolerate pruning. It is a good choice for attracting bees to your yard. It has no significant negative characteristics.
American Sentry Linden is recommended for the following landscape applications;

Vertical Accent
Planting & Growing
American Sentry Linden will grow to be about 40 feet tall at maturity, with a spread of 20 feet. It has a high canopy with a typical clearance of 7 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for 70 years or more.
This tree should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selection of a native North American species.
Snowdance™ Japanese Tree Lilac
Sienna Glen Maple
Acer x freemanii 'Sienna'
The Sienna Glen Maple tree is a naturally occurring hybrid found on an abandoned farmstead in Lake Elmo, Minnesota. Its distinct, upright, pyramidal growth habit, which is readily apparent as a young tree, grows and becomes a broad pyramid when mature. The Sienna Glen exhibits vigorous growth yet withstands strong winds. The branches are borne more closely together along the trunk (than those of Autumn Blaze) and are finer and more delicate, yet the wood is harder and shorter and exhibit less drooping. The smaller, fine textured green leaves are dark green with a silvery underside and turn a variable mix of yellow and orange with a pinkish tinge at the highest part of the crown. As the fall color finishes, it turns a burnt orange. This beauty tolerates higher soil pH unlike Autumn Blaze, not exhibiting any chlorosis. Hardiness zone 4 (testing done in zone 3). Mature growth is around 60' tall x 40' wide.

Noteworthy Characteristics
Quercus rubra, commonly called red oak or northern red oak, is a medium sized, deciduous tree with a rounded to broad-spreading, often irregular crown. Typically grows at a moderate-to-fast rate to a height of 50-75' (often larger in the wild). Dark, lustrous green leaves (grayish-white beneath) with 7-11, toothed lobes which are sharply pointed at the tips. Leaves turn brownish-red in autumn. Insignificant flowers in separate male and female catkins appear in spring. Fruits are acorns (with flat, saucer-shaped cups) which mature in early fall. An abundant crop of acorns may not occur before this tree reaches 40 years old. A Missouri native tree which typically occurs on northern- and eastern-facing wooded slopes throughout the State.
Genus name comes from the classical Latin name for oak trees.
Specific epithet means red.
Problems
Generally a durable and long-lived tree. Susceptible to oak wilt which is a systemic fungal disease that has no cure. Chlorosis (yellowing of the leaves while the veins remain green) often occurs when soils are not sufficiently acidic.
