|Malus 'Adirondack' Crabapple
Botanical Name: Malus 'Adirondack'
(NA 54943; PI 499828)
Hardiness: U.S.D.A. Zone 4 - 8
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.
'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.
Height and Width: 18 feet tall and 16 feet crown width at 20 years.
Narrow obovate, upright-branched small tree. Maintains upright form with age.
Leathery dark green leaves. The foliage is highly tolerant to cedar apple rust, apple scab, and powdery mildew.
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.
A pome. Abundant, bright orange-red, hard, small (1/2-inch) fruit persist until early winter. Relished by birds after softened by freezing.
Adaptable to diverse soil, moisture, and climatic conditions. Requires virtually no pruning to maintain its shape nor chemical controls for the common crabapple diseases.
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.
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.||EXCLAMATION! ™ London planetree

Common Name: Northern Red Oak | Type: Tree
Family: Fagaceae | Native Range: Eastern North America
Zone: 4 to 8 | Height: 50.00 to 75.00 feet | Spread: 50.00 to 75.00 feet
Bloom Time: May | Bloom Description: Yellowish-green
Sun: Full sun | Water: Dry to medium
Maintenance: Low | Suggested Use: Shade Tree, Street Tree
Flower: Insignificant | Leaf: Good Fall
Tolerate: Drought, Dry Soil, Black Walnut, Air Pollution
Easily grown in average, dry to medium moisture, acidic soil in full sun. Prefers fertile, sandy, finely-textured soils with good drainage.
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.
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.||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.

Celtis occidentalis, commonly called common hackberry, is a medium to large sized deciduous tree that typically grows 40-60’ (less frequently to 100’) tall with upright-arching branching and a rounded spreading crown. Trunk diameter ranges from 1-3’ (less frequently to 4’). This tree is a U.S. native that is widely distributed throughout the east and midwest. It is common in Missouri where it typically occurs statewide in low woods along streams and in drier upland slopes (Steyemark). Mature gray bark develops corky ridges and warty texture. Insignificant, mostly monoecious, greenish flowers appear in spring (April–May), with male flowers in clusters and female flowers solitary. Female flowers give way to an often abundant fruit crop of round fleshy berry-like drupes maturing to deep purple. Each drupe has one round brown seed within. Fruits are attractive to a variety of wildlife. Birds consume the fruits and disperse the seeds. Fleshy parts of the fruit are edible and somewhat sweet. Ovate to oblong-ovate, rough-textured, glossy to dull green leaves (2-5” long) have mostly uneven leaf bases and are coarsely toothed from midleaf to acuminate (sharply pointed) tip. Undistinguished yellow fall color.
Genus name comes from the Greek name for another tree.
Specific epithet means Western.
Hackberry nipple gall is so common in the St. Louis area that it is often used as an aid in identifying the tree. Although the galls do not hurt the tree, they often significantly disfigure the leaves. Witches’ broom (dwarfed, dense, contorted twig clusters at the branch ends) is also somewhat common. It also does little harm to the tree, but can be quite unsightly. Powdery mildew, leaf spot and root rot may occur. Watch for lacebugs and scale.|
