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.
Height: 15 m
Crown: pyramidal to broad pyramidal, dark, dense crown
Bark and branches: smooth, grey-brown
Leaf: 3 to 5 lobes, shiny, bright green with light red stem, 8-10 cm

Fruits: single seeds, winged, always in pairs, few or entirely absent,
fruitless cultivar
Spines/thorns: none
Toxicity: non-toxic (usually)
Soil type: any, but not too limy
Paving: tolerates paving
Winter hardiness zone: 4 (-34,4 to -28,9 °C)

Application: avenues and broad streets, parks, squares, theme parks, cemeteries, large gardens
American Sentry | Tilia American Sentry
Height: 40 feet
Spread: 20 feet
Sunlight: full sun
Hardiness Zone: 3a
Other Names: Basswood, American Linden
Description:
A stately tree with a narrow upright habit of growth for smaller yards and spaces, features tightly upright branching, leaves turn rich gold in fall; fast growing and vigorous, resistant to insect attacks
Ornamental Features
American Sentry Linden features subtle clusters of fragrant buttery yellow flowers with tan bracts hanging below the branches in early summer. It has dark green foliage throughout the season. The large heart-shaped leaves turn an outstanding gold in the fall. The fruit is not ornamentally significant.
Landscape Attributes
American Sentry Linden is a dense deciduous tree with a strong central leader and a narrowly upright and columnar growth habit. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.
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;

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.
Malus 'Adirondack' Crabapple
Botanical Name: Malus 'Adirondack'
(NA 54943; PI 499828)
Family: Rosaceae
Hardiness: U.S.D.A. Zone 4 - 8
Development
Five hundred open-pollinated seedlings of Malus halliana were artificially inoculated with fire blight under control conditions. Of the sixty surviving seedlings, several showed field resistance to scab, cedar-apple rust, and powdery mildew when exposed to natural inoculum from heavily infected, susceptible plants during eleven years of field trial. 'Adirondack' was selected from this seedling population in 1974 by Donald R. Egolf and released in 1987.
Significance
'Adirondack' exhibits a combination of many desirable traits that make it a near-perfect crabapple. The narrow obovate, upright-branched growth habit combines with an annual bloom cycle, abundant, small, persistent fruit, slow to moderate growth rate, and multiple disease tolerance that is rare in crabapple. Highly rated for both aesthetics and disease resistance by the International Ornamental Crabapple Society.
Description
Height and Width: 18 feet tall and 16 feet crown width at 20 years.
Habit
Narrow obovate, upright-branched small tree. Maintains upright form with age.
Foliage
Leathery dark green leaves. The foliage is highly tolerant to cedar apple rust, apple scab, and powdery mildew.
Flowers
Annual flowering. Dark carmine buds mature to a lighter red and open to white, waxy, heavy-textured, wide-spreading flowers with traces of red; slightly fragrant.
Fruit
A pome. Abundant, bright orange-red, hard, small (1/2-inch) fruit persist until early winter. Relished by birds after softened by freezing.
Culture
Adaptable to diverse soil, moisture, and climatic conditions. Requires virtually no pruning to maintain its shape nor chemical controls for the common crabapple diseases.
Propagation
Most commercial propagation is by budding or grafting onto compatible rootstocks. Roots easily from softwood cuttings in late spring, under mist, 3000 ppm IBA, in 4 weeks.
Landscape Use
Effective for foundation plantings of buildings or formal gardens; as a specimen for space-limited situations; a strong focal accent in the shrub border or residential garden; park and recreational area screen; roadside or street tree where shade is not important.
