Description
Quercus bicolor
Swamp White Oak
Quercus bicolor, commonly called Swamp White Oak, is a medium sized, deciduous tree with a broad, rounded crown and a short trunk which typically grows at a moderate rate to a height of 50-60′ (sometimes larger). Leaves are dark, shiny green above and silvery white beneath, with 5-10 rounded lobes or blunt teeth along the margins. Fall color is yellow, but sometimes reddish purple. Insignificant flowers in separate male and female catkins in spring. Fruits are acorns which mature in early fall. Indigenous to north, central, and eastern Missouri in moist to swampy locations in bottomlands and lowlands, such as along streams and lakes, valleys, floodplains and at the edge of swamps. Also has surprisingly good drought resistance.

Syringareticulata 'Ivory Silk'
Ivory Silk Japanese tree lilac
Ivory Silk' is a small tree or large shrub which typically grows 20-25' tall with a rounded crown. Creamy white, fragrant, single flowers are arranged in dense, terminal clusters (panicles to 12" long). Blooms later than most other species of lilac (late May to early June in St. Louis). Elliptic to ovate, dark green leaves (to 5" long). Attractive reddish-brown bark.
Effective as a specimen in the landscape. Tree forms are effective along streets, in lawns, near decks/patios or in foundations. Shrub forms are effective in borders or small groups. May be used as a screen along property lines.

Acer × freemanii 'Jeffersred' AUTUMN BLAZE
Common Name: Freeman maple | Type: Tree
Family: Sapindaceae | Zone: 3 to 8
Height: 40.00 to 55.00 feet | Spread: 30.00 to 40.00 feet
Bloom Time: Rarely flowers | Bloom Description: Greenish-yellow to red
Sun: Full sun to part shade | Water: Medium to wet
Maintenance: Low | Suggested Use: Shade Tree, Street Tree, Rain Garden
Leaf: Good Fall | Tolerate: Wet Soil
Culture
Easily grown in average, medium to wet, well-drained soils in full sun to part shade. Prefers moist, acidic soils with good drainage. Established trees have some tolerance for drought conditions.
Noteworthy Characteristics
Acer x freemanii, commonly called Freeman maple, is a hybrid of red maple (A. rubrum) and silver maple (A. saccharinum). The Freeman maple cultivars commonly sold in commerce today reportedly combine some of the best features of both parents, namely, solid structure, attractive form and showy fall color (from red maple) and adaptability and rapid growth (from silver maple). Oliver M. Freeman of the National Arboretum made the first controlled crosses between red maple and silver maple in 1933. Edward Murray named this hybrid cross in 1969 in honor of Oliver M. Freeman. Notwithstanding the foregoing, crosses between red and silver maples occur not only by controlled propagation but also naturally in the wild. It is sometimes difficult to identify a Freeman hybrid because of the complexity of crosses and backcrosses that may occur.
Cultivars are sometimes listed for sale by nurseries under Acer rubrum instead of Acer x freemanii.
Genus name is the Latin name for a maple tree.
Specific epithet and common name honors Oliver Freeman who first grew A. x freemani at the U. S. National Arboretum in 1933.
‘Jeffersred’, sold under the trade name of AUTUMN BLAZE, is an older cultivar that was discovered by nurseryman Glenn Jeffers in the late 1960s. This is an upright, fast-growing, deciduous tree that will typically grow 40-55’ tall with ascending branching and a dense, broad-oval crown. Each medium green leaf is deeply cut with five pointed lobes. As the trade name suggests, the foliage turns into an autumn blaze of orange-red to scarlet-red fall color. Flowers and fruit for this hybrid are very sparse. U.S. Plant Patent PP04,864 issued July 6, 1982.
Problems
No serious insect or disease problems. Young plants susceptible to leafhoppers and scale. Borers.
St Croix™ American Elm
Malus 'Purple Prince'
Common Name: flowering crabapple | Type: Tree
Family: Rosaceae | Zone: 4 to 8
Height: 18.00 to 20.00 feet | Spread: 18.00 to 20.00 feet
Bloom Time: April | Bloom Description: Rose red
Sun: Full sun | Water: Medium
Maintenance: Low | Suggested Use: Flowering Tree
Flower: Showy, Fragrant | Attracts: Birds, Hummingbirds, Butterflies
Fruit: Showy, Edible | Tolerate: Air Pollution
Culture
Best grown in medium moisture, well-drained, acidic loams in full sun. Adapts to a wide range of soils. Established trees have some drought tolerance. Although some flowers may be lost, it is best to prune this tree as needed in late winter. Spring pruning should be avoided as it produces fresh, open cuts where fireblight bacterium can enter.
Noteworthy Characteristics
Malus is a genus of about 35 species of deciduous trees and shrubs from Europe, Asia and North America.
Genus name from Latin is an ancient name for apple.
'Purple Prince' is a cross of (Malus ‘Bluebeard’ by Malus ‘Liset’) by Malus ‘Garnet’ that was developed by John L. Fiala of Medina, Ohio. The patent has been assigned to the J. Frank Schmidt & Son Co. nursery of Boring, Oregon. ‘Purple Prince’ is a small rounded tree with upward spreading branches that grows 18 to 20 ft. tall and wide. In spring, it has ovate purple-bronze leaves that gradually turn green in summer and then golden in fall. Its rosy red single flowers mature into round 3/8 to 1/2 in. purple fruits that persist into winter and attract birds. ‘Purple Prince’ has excellent resistance to scab and cedar apple rust and good resistance to fireblight and mildew. It is considered to be a rapid grower but is less likely to have problems with stem splitting. U.S. Plant Patent #8,478 issued November 30, 1993.
Problems
The main diseases of crabapple are scab, fire blight, rusts, leaf spot and powdery mildew. Potential insect pests are of lesser concern and include tent caterpillars, aphids, Japanese beetles, borers and scale. Spider mites may occur.
'Purple Prince' has good disease resistance to the main diseases of crabapples.
Firefall™ Maple
Acer x freemanii 'Firefall'
Firefall™ has an upright-oval form with good branch angles. This selection is male and therefore does not produce nuisance seeds. The foliage is an attractive medium green throughout the summer. Fall color is bright orange to scarlet and develops fairly early. This is a distinct advantage over some existing Freeman maple cultivars that color later and often do not develop much color in northern regions before freezing temperatures cause the foliage tomdrop.
