Overview
Common Name: Japanese maple
Type: Tree
Family: Sapindaceae
Zone: 5 to 8
Height: 15.00 to 20.00 feet
Spread: 15.00 to 20.00 feet
Bloom Time: April
Bloom Description: Red
Sun: Full sun to part shade
Water: Medium
Maintenance: Low
Flower: Insignificant
Leaf: Colorful, Good Fall
Fruit: Showy
Tolerate: Rabbit, Black Walnut
Culture
Easily grown in moist, organically rich, slightly acidic, well-drained soils in full sun to part shade. Grows well in sandy loams. May be grown in full sun in the northern parts of its growing range, but prefers some part afternoon shade in the southern parts (including St. Louis) of its growing range. New foliage may scorch in full sun locations in hot summers areas, particularly if soils are not kept consistently moist. Mulch helps retain soil moisture and keep roots cool. Site in locations protected from strong winds. Avoid hot and dry sites. Fertilize in spring before leaves emerge. Pruning is best kept to a minimum, but if needed should be done in late fall to mid winter. Spring or summer pruning often results in significant bleeding.
Noteworthy Characteristics
Acer palmatum, commonly called Japanese maple, is a deciduous shrub or small tree that typically grows to 10-25' (infrequently to 40') tall. It is native to Japan, Korea and China. General plant form is rounded to broad-rounded, often with low branching. Each palmate green leaf (2-5" long) has 5 or 7 but less frequently 9 pointed toothed lobes. Small reddish-purple flowers in umbels bloom in mid spring (April). The flowers are rather attractive close up, but are not particularly showy from a distance. Flowers are followed by samaras (to 3/4" long) in pairs. Samaras ripen in September-October. Fall color includes shades of yellow, red-purple and bronze. Cultivars (often grafted) are quite variable.
Genus name is the Latin name for a maple tree.
Specific epithet is in reference to the palmate nature of the leaves. Each leaf has several lobes (typically 5–7) that all originate from one point looking like an open hand with outstretched fingers.
'Bloodgood is a non-dissected type that grows into a small, rounded, deciduous tree which typically grows to 15-20' tall and features purplish-red flowers in spring, deep reddish-purple summer foliage, red samaras in late summer to early fall and good crimson-red fall color. As with many maples, the flowers are rather attractive close up, but are not particularly showy from a distance. Palmate leaves (5-7 lobes) are 2-5" long. May also be grown as a multi-stemmed shrub.
Problems
No serious insect or disease problems. Potential disease problems include stem canker, leaf spots, fusarium, verticillium wilt, botrytis, anthracnose and root rots. Potential insect pests include aphids, scale, borers and root weevils. Mites may be troublesome. Foliage tends to leaf out early in spring and is subject to damage from late spring frosts. Chlorosis may occur in high pH soils.
Garden Uses
Japanese maples are generally grown for their attractive foliage and shape. Specimen/accent or group around the home or yard or periphery of the border. Good sun-dappled understory tree. Woodland garden margins. Screen. Bonsai.

Overview
Common Name: weeping higan cherry
Type: Tree
Family: Rosaceae
Zone: 5 to 8
Height: 15.00 to 25.00 feet
Spread: 15.00 to 25.00 feet
Bloom Time: April
Bloom Description: Light pink to rose pink
Sun: Full sun to part shade
Water: Medium
Maintenance: Medium
Suggested Use: Flowering Tree
Flower: Showy
Leaf: Good Fall
Attracts: Birds
Culture
Best grown in moist, fertile, well-drained loams in full sun to part shade. Best flowering in full sun. Avoid dry soils.
‘Pendula Rosea’ is often top grafted at the 5-6’ level to an understock. Grafted plants may produce non-weeping suckers that should be promptly removed.
Noteworthy Characteristics
Prunus pendula is an ornamental weeping cherry tree that is native to Japan. The white or pink flowers bloom in 2 to 5-flowered umbels in late winter to early spring before the leaves emerge. Flowers are followed by rounded pea-sized fruits (to 1/3” diameter) that are sometimes sparse. Fruits eventually mature to black, but are basically inedible. Fruits may not appear in some years. Elliptic to ovate, doubly serrate, green leaves (to 4” long) turn red or yellow in fall.
Genus name from Latin means plum or cherry tree.
Specific epithet means pendulous or hanging down.
'Pendula Rosea’ is a cultivar that typically grows 15-25’ tall with a pronounced weeping form and light pink to rose-pink flowers. Nomenclature on this tree is a bit confusing. Many weeping cherries including the within cultivar may still be incorrectly sold as cultivars of Prunus x subhirtella.
Problems
Ornamental cherry is generally considered to have good disease resistance. Like all cherries, it is susceptible to a large number of insect and disease problems. Potential diseases include cankers, black knot, leaf spot, die back, leaf curl, powdery mildew, root rot and fireblight. Potential insects include aphids, scale, borers, leafhoppers, caterpillars, tent caterpillars and Japanese beetles. Spider mites may also be troublesome.
Garden Uses
Weeping specimen for the landscape.

Noteworthy Characteristics
Prunus is a genus of about 200 species of deciduous and evergreen trees and shrubs found in north temperate areas, the Andes of South American and in mountainous areas of Southeast Asia. Some are grown for their showy flowers, colorful foliage and/or attractive bark; and others for fruit, which includes cherry, plum, apricot, nectarine and peach.
Genus name from Latin means plum or cherry tree.
'Snofozam', sold under the trade name of SNOW FOUNTAINS, is a slow-growing, weeping, ornamental cherry that is sold in a variety of forms: (1) a compact, naturally weeping tree (most other weeping cherries are topgrafted) that typically grows 8-15' tall, or (2) a compact tree topgrafted at 6' or (3) a ground cover. As a weeping tree, its cascading branches dip all the way to the ground, giving the appearance of a white or snow fountain when covered with pure white flowers in early spring. Flowers give way to small, sparse, black, inedible fruits. Dark green leaves (to 3 1/4" long) turn attractive shades of gold and orange in autumn. This cultivar is known by several different names, including 'Snofozam', 'White Fountain' and 'Snow Fountains'.
Problems
Susceptible to a large number of insect and disease pests. Potential diseases include leaf spot, die back, leaf curl, powdery mildew, root rot and fireblight. Potential insects include aphids, scale, borers, leafhoppers, caterpillars, tent caterpillars and Japanese beetles. Spider mites may also be troublesome.
Garden Uses
Specimen for lawns or small areas around the home. Border peripheries. Japanese gardens. The ground cover form can be used as a ground cover, on banks or cascaded over walls.

Culture
Grow in average, medium moisture, well-drained soils in full sun to part shade. Somewhat wide range of soil tolerance, but prefers moist, neutral to alkaline, well-drained loams. Intolerant of dry conditions. Best in full sun, but generally appreciates some light afternoon shade in hot summer climates such as the St. Louis area. Avoid full shade where foliage density will substantially decrease. Avoid exposed, windy sites.
Noteworthy Characteristics
Thuja occidentalis, commonly known as American arborvitae, Eastern arborvitae, Eastern white cedar or Northern white cedar, is a dense, conical to narrow-pyramidal (sometimes maturing to broad-pyramidal), often single-trunked, evergreen tree that is native to eastern and central Canada south to northern Illinois, Ohio and New York with scattered populations further south in the Appalachians to North Carolina. Mature trees may reach 40-60' tall in the wild over time, but in cultivation typically grow much smaller to 20-30' tall. Scale-like, aromatic, yellow-green to green foliage appears in flattened sprays. Red-brown bark will exfoliate on mature branches and trunks.
Genus name is the Greek name for a kind of juniper (Juniperus.)
Specific epithet means from the Western (Occidental) world.
The common name of arborvitae (tree of life) comes from early French settlers to North America who learned from Native Americans that the tree’s foliage could be used to treat scurvy.
'Smaragd' is a semi-dwarf cultivar with a compact, narrowly pyramidal habit. Glossy bright green, scale-like foliage in flat sprays. Urn-shaped cones to 1/2" long mature in autumn to reddish brown. Most often seen as a 7-15' (infrequently to 20') tall shrub with a spread of 3-4'. Cultivar is synonymous with and sometimes also called 'Emerald' or 'Emerald Green'.
Problems
No serious insect or disease problems. Leaf blight may cause some foliage to spot and drop. Watch for canker. Leaf miner may damage leaf tips. Bagworms, mealybug, scales and spider mites are occasional visitors. Foliage may show some winter burn (turns yellow-brown) in exposed sites. Susceptible to damage/stem breakage in winter from ice and snow accumulations.
Garden Uses
Good specimen or accent. Hedge, background plant or foundation plant.
