Betula populifolia ‘Whitespire’

Whitespire Birch

‘Whitespire’ is best known for its upright form, non-exfoliating white bark, dark green leaves and attractive yellow fall color. Vegetatively propagated plants of this cultivar are considered to have better resistance to bronze birch borer. ‘Whitespire’ was originally named as a cultivar of Betula platyphylla var. japonica when introduced into commerce in 1983, but that designation was subsequently changed when it was determined ‘Whitespire’ was in fact a gray birch.

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.

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.Celtis occidentalis Species Native to Missouri Common Name: hackberry  | Type: Tree Family: Cannabaceae Native Range: Central and northeastern North America Zone: 2 to 9 | Height: 40.00 to 60.00 feet Spread: 40.00 to 60.00 feet  | Bloom Time: April to May Bloom Description: Green | Sun: Full sun to part shade Water: Medium to wet  | Maintenance: Low Suggested Use: Shade Tree, Street Tree, Rain Garden Flower: Insignificant | Attracts: Birds, Butterflies Fruit: Edible | Tolerate: Drought, Clay Soil, Wet Soil, Air Pollution Culture Best grown in moist, organically rich, well-drained soils in full sun. Tolerates part shade. Also tolerates wind, many urban pollutants and a wide range of soil conditions, including both wet, dry and poor soils. Noteworthy Characteristics 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. Problems 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.Acer rubrum 'Northwood' Common Name: red maple Type: Tree Family: Sapindaceae Zone: 3 to 9 Height: 40.00 to 60.00 feet Spread: 25.00 to 40.00 feet Bloom Time: March to April Bloom Description: Red Sun: Full sun to part shade Water: Medium to wet Maintenance: Low Suggested Use: Shade Tree, Street Tree, Rain Garden Flower: Showy Leaf: Good Fall Tolerate: Wet Soil, Air Pollution Culture Easily grown in average, medium to wet, well-drained soil in full sun to part shade. Tolerant of a wide range of soils, but prefers moist, slightly acid conditions. Very cold hardy. Noteworthy Characteristics Acer rubrum, commonly called red maple, is a medium-sized, deciduous tree that is native to Eastern North America from Quebec to Minnesota south to Florida and eastern Texas. It typically grows 40-60’ tall with a rounded to oval crown. It grows faster than Norway and sugar maples, but slower than silver maple. In northern states, red maple usually occurs in wet bottomland, river flood plains and wet woods, but in Missouri it typically frequents drier, rocky upland areas. Emerging new growth leaves, leafstalks, twigs, flowers, fruit and fall color are red or tinged with red. Quality of red fall color on species plants is variable. Leaves (to 2-5" long) have 3 principal triangular lobes (sometimes 5 lobes with the two lower lobes being largely suppressed). Lobes have toothed margins and pointed tips. Leaves are medium to dark green above and gray green below. Flowers on a given tree are primarily male or female or monoecious and appear in late winter to early spring (March-April) before the leaves. Fruit is a two-winged samara. Genus name is the Latin name for a maple tree. Specific epithet of rubrum meaning red is everywhere in evidence: red flowers in dense clusters in late March to early April (before the leaves appear), red fruit (initially reddish, two-winged samara), reddish stems and twigs, red buds, and, in the fall, excellent orange-red foliage color. 'Northwood' will grow 40-60' tall with a rounded to oval crown. Leaves are shiny green above and pale green beneath, 3-5 lobed and 3-6" across. University of Minnesota introduction. This cultivar is best grown in northern states because it needs cool weather and frost for best fall color, and will generally not produce good fall color in the deep south. Problems No serious insect or disease problems. Watch for aphids, leafhoppers, borers, scale and caterpillars. Verticillium wilt attacks the vascular system and can be fatal. Canker, fungal leaf spot and root rots may also occur. Wind and ice may break some branches. Leaf hoppers can cause substantial damage. Garden Uses Plant as a specimen tree for the lawn, street or park. It is of note that this tree has a shallow, flattened root system that may buckle nearby sidewalks or driveways if planted too close.EXCLAMATION! ™ London planetree Platanus acerifolia 'Morton Circle' Is an introduction that is resistant to anthracnose and frost cracking.
