- Tree Selection Guide (Table 1)
Deciduous trees (trees that lose all or most of their leaves at the end of a growing
season) affect the well-being and appearance of Oklahoma communities. They contribute
to an atmosphere of peace of mind and relaxation. One of the most effective ways to
improve community appearance is to plant trees. Trees also increase recreational opportunities,
bolster local property values and aid in reduced noise pollution. Because there are
so many deciduous trees for use in landscaping, carefully select appropriate trees
for your needs.
Selection should be based on several different factors. The intended purpose should
influence selection of trees with appropriate shape, size and other physical characteristics.
Deciduous trees are used for shade, ornamentation, screening, windbreak, sound-reducing
purposes and to attract wildlife. Deciduous trees also can be selected to provide
edible fruit or nuts. When properly selected and maintained, trees can increase property
values. Selecting native or adapted trees is important for long-term survival and
reduced maintenance.
Providing shade usually requires tall, sturdy, long-living species. Density of foliage,
which determines the amount of shade, is important. A tree such as red maple will
produce a very dense shade that may prevent other plants from growing under it, while
a Kentucky coffeetree will produce a light partial shade, allowing some plants enough
sunlight to grow. Deciduous trees should be used to shade the south and west windows
of a home in the summer, allowing the sun to penetrate in the winter.
Screens usually require plants that produce dense foliage. Evergreen plants are usually
chosen for screening, but deciduous plants can also be used. Windbreaks must be able
to survive rigorous climatic conditions. Barrier plantings usually require sturdy
plants with dense growth.
Ornamental attributes are quite varied. Deciduous trees can be selected for flowers,
colorful fruit, interesting summer foliage, fall or winter color, interesting bark
or interesting shapes of the plants themselves.
Consider the size of mature trees and where they are to be used. Trees that grow tall,
such as the American elm, burr oak, sycamore and tulip tree, are suitable for larger
buildings and spaces. They tend to dominate or hide one-story buildings. For attractive
and proper balance with one-story buildings, trees shorter than about 35 feet when
full grown are recommended. Careful consideration of mature size will reduce the need
for pruning. Avoid placing trees too close to the home, as they can cause damage to
the roof and fill gutters with plant debris. Roots of some species too close to the
home may cause damage to the foundation. Plant trees at a minimum distance of half
the mature canopy width away from the home.
Shape is especially important in selecting trees for ornamental and shade purposes.
Tall trees with long, spreading, vase shapes or weeping branches give abundant shade.
Small trees and trees of other shapes, including narrow, columnar, pyramidal and clump
forms and the low-growing types, such as hawthorn, crabapple and dogwood have ornamental
purposes but do not provide abundant shade.
Environmental conditions should influence the selection of trees. Size of the planting
area is important, as are site characteristics such as sun or shade, wet or dry, exposure
to winter winds or pollution. Trees selected should be tolerant of existing conditions
and hardy in the climate zone where it is planted. The amount and quality of underground
rooting space impacts tree growth, too. Tree roots are typically found in the top
18 inches of soil and often extend past the canopy. Trees growing in restricted root
zones, such as between the sidewalk and street, or in new subdivisions with compacted
sub-soil, often succumb to insect pests and diseases quicker, exhibit slower growth
rates and reach shorter mature heights than trees growing in open spaces.
Finally, consider how much maintenance the tree will require and any possible disadvantages,
including susceptibility to attack by disease and insect pests; soft or brittle wood
that is easily damaged by wind and ice; fruits and seeds that are large, messy, smelly
or otherwise obnoxious; and abundant shedding of twigs and small branches. Some examples
of these conditions are the killing of ash by borers, breaking of Siberian elm branches
by wind and ice and the production of bad-smelling fruit by the female ginkgo. The
production of fruit by the mulberry, which attracts birds, can also be an undesirable
characteristic. Since this fruit is soft and decomposes rapidly when ripe, it is messy
on walks and attracts flies and other insects.
Fast-growing trees, such as silver maple and poplars, typically possess weak wood
and are often short-lived. In addition, trees with weak, narrow crotch angles are
sometimes susceptible to limb damage from snow/ice storms. Pruning can help eliminate
narrow branch attachments, but some trees, such as Bradford pear, inherently have
narrow crotch angles and pruning will not be a solution. A few trees exist with strong
narrow branch angles such as Japanese Zelkova and Japanese tree lilac, which can be
successfully grown. Fast-growing trees and trees with weak, narrow crotch angles should
be planted away from houses and other buildings to avoid potential damage from falling
limbs. Under good growing conditions, trees known for slow growth rates, such as oaks,
can grow up to two feet per year, and will provide long-term benefits. Asthma/allergy
sufferers should avoid planting seedless or fruitless tree cultivars, which often
have staminate (male) flowers that produce pollen.
Trees recommended below are merely examples of what grows well in Oklahoma. Lists
provided are not comprehensive, but are to assist the homeowner in working with their
local horticulturists and professionals. If looked at for typical reasons, please
realize, that some plants mentioned ARE NOT the best species to include in the landscape.
Compromise in plant selection may be necessary for the specific purpose to be realized.
When “spp.” is seen in a name, that implies multiple species and or hybrids are available
and could be candidates.
Plants with an asterisk, while a desirable species, may not be found in all nurseries
or garden centers, however, a nursery professional can suggest viable substitutes
with similar attributes or possibly special order the tree. In some cases these trees
may be found in online tree sites as well.

Undesirable Trees
The following trees, though common and often used due to their rapid growth, may not
be the best choice for the typical residential landscape. Due to their fast growth
these trees are often more susceptible to disease and insect attack as well as storm
damage.
Cottonwood, Eastern (Populus deltoides). Grows too big for a typical landscape. Over time roots grow on the surface. Fast
growing, weak wooded, messy, and susceptible to diseases and insects. Male selections
may be appropriate for certain situations. Consult with retailer.
Maple, Silver (Acer saccharinum). Shallow root system that can invade flowerbeds. Fast growing, resulting in weak,
brittle wood. Appropriate only in limited settings.
Pear, Callery cultivars (Pyrus calleryana) Very tolerant of soil types and drought conditions and has excellent spring flowers
and fall color. However, branching structure, especially of Bradford is poor, resulting
in storm damage as it ages. Cross pollination of Callery pear cultivars and the species
results in fruit, which has put this tree on the invasive species watch list. Consult
with retailer to consider appropriate ornamental pears for specific needs.
Poplars (Populus spp.). Extremely tolerant of soil conditions. Surface roots. Many disease and insect
problems. Weak wooded. Attractive, but inferior tree. Appropriate only in specific
settings; see retailer for alternative species.
Tree Selection Guide (Table 1)
Mature height (H) will vary considerably by cultivar and site and is shown here assuming
adequate care: Low: <20 feet; Medium: 20 to 40 feet; and High: >40 feet.
Growth rate (GR) refers to height growth for the first 10 years after a tree is planted
and is shown as follows: Low: <12 inches/year; Medium: 12 to 24 inches/year; and High:
>24 inches/year.

Table 1. Deciduous Trees.
| Species | Region | Growth Rate | Height | Comments |
|---|---|---|---|---|
| Alder (Alnus spp.) | NW, NE | H | H | Interesting flowers and fruits. Tolerates wet soils. |
| Ash, Green (Fraxinus pennsylvanica) | A | H | H | Grows well in a variety of soils. Good fall color. Borers may be a problem. |
| Ash, White (Fraxinus americana) | A | M | M | Not as adaptable to various soils as green ash. Needs well-drained soil. Borers may be a problem. |
| Beech, American (Fagus grandifolia) | NE, SE | L | H | Beautiful tree in spring and summer. Prefers moist, well-drained, sandy soils. |
| Birch, River (Betula nigra) | NE, SE, NW, SW | H | H | Less susceptible to borers. Thrives in moist soils of various textures. Leaves may turn yellow and drop during the heat of the summer. Best birch for Oklahoma. |
| Boxelder (Acer negundo) | A | H | H | Adaptable to wide variety of soils. Boxelder bugs are attracted to this tree and can be a nuisance. |
| Buckeye, Bottlebrush (Aesculus parviflora) | NE, SE | L | L | Long panicles of white flowers in early summer. Moist, well-drained, acid soil is preferred, though it is adaptable. Full sun or as an understory tree in part shade. |
| Buckeye, Ohio (Aesculus glabra) | NE, SE | Greenish yellow flowers in spring; best in moist, well-drained, slightly acid soil. | ||
| Buckeye, Red (Aesculus pavia) | NE, SE | M | M | Grows best in deep, rich, well-drained, moist, sandy loam soils. Leaf scorch as well as some diseases and insects can be a problem if not grown in ideal conditions. Provide partial shade. |
| Buckeye, Texas (Aesculus glabravar. arguta) | NE, SE | M | L | Yellow-green flowers. |
| Buckthorn, Carolina or Indiancherry (Frangula caroliniana) | A | M | L | Oklahoma Proven Selection. Attractive fruit. |
| Catalpa, Southern (Catalpa bignonioides) | A | M | M | Will grow in just about any soil. Flowers in spring are quite showy. Tree is rather weak wooded and messy. |
| Chestnut, Chinese (Castanea mollissima) | NE , SE | M | L | Prefers full sun and reasonably well-drained soil. Drought tolerant. Edible fruit. |
| Chitalpa (× Chitalpa tashkentensis) | A | M | H | × Chitalpa tashkentensis is an inter-generic hybrid cross between desert willow (Chilopsis linearis) and southern catalpa (Catalpa bignonoides). Although drought tolerant, trees generally perform best with consistent and even moisture. Bell-shaped, pink to white, catalpa-like flowers bloom at the branch ends in summer. Powdery mildew can be a significant problem in growing areas with high summer humidity or if located in too much shade. |
| Chittimwood (Sideroxylon lanuginosum) | A | L | M | Underutilized native, adaptable, drought tolerant tree. |
| Coffeetree, Kentucky (Gymnocladus dioicus) | A | M | H | Prefers deep, rich, moist, sandy loam soils, but very tolerant of a wide range of soil conditions and drought.
