“Trees Across Arvada” offers you the opportunity to purchase low cost shade trees. The trees, mostly low to moderately low water demand varieties, are 8-12 feet tall and 1-1 ¼ inches in diameter.
“Trees Across Arvada” is a program of the Colorado Tree Coalition, a nonprofit statewide organization dedicated to preserving, renewing and enhancing Colorado’s community forests.
Trees help us by:
cooling our neighborhoods in summer with shade and transpiration
cleaning the air of pollution by catching particulates on their leaves
turning carbon dioxide into oxygen for us to breathe
slowing down storm drainage flooding
reducing water consumption of plants protected by their shade
lowering summer utility bills by shading
adding value to our property
planting trees improves the quality of life

Description of Trees for April 2008*
Trees are listed in categories of large/medium and small, and then alphabetically by English name.
Drought Tolerance: All newly transplanted trees require careful watering in all seasons. Our dry winters are very hard on trees. Once established (3-4 years after planting), all 2008 trees are mostly low or moderately-low water demand trees.
Growth Rates are not given because they are somewhat site specific, depending on local soil fertility/texture, watering and other factors. Generally, none of the trees offered are “fast growing” because most “fast growers” have soft wood with weaker branches that are more likely to break in early fall and late spring snowstorms.
Bare Root (BR) or Balled & Burlaped (B & B) Trees?
Bare Root (BR) trees are dormant upon arrival, and must be planted immediately so the roots do not dry out. BR trees may seem more vulnerable, but if handled correctly, have as good or better chance of survival than Balled & Burlaped (B&B) trees. B&B trees lose much more of their root system when dug for transplanting than BR trees.
Height and width of trees are estimated and adjusted for our area, and, therefore, may differ from figures given in resource books based on other areas.
For more information call the Colorado State University Extension office in Jefferson County, 303-271-6620, or visit the CSU Extension website at www.ext.colostate.edu click on “Horticulture,” and then “Fact Sheets.”
Large and Medium height trees that should NOT be planted under power lines.
Bur Oak (Quercus macrocarpa) Balled & Burlapped, 50-100 lbs. - $43.00
A fine, large specimen tree, also called Mossycup Oak (from its acorn). It is inspiring because of its eventual size and hardiness. Bur Oaks reach 60’ in height and width. The pyramidal to oval shape becomes a broad crown with stout branches at maturity. The lustrous green leaves turn yellow-green, yellow, and finally yellow-brown in fall. The rough dark gray to gray-brown bark becomes deeply ridged and furrowed. It is believed that the thick bark helped Bur Oak survive the heat of prairie fires.
Bur Oaks grow well in various soil types and are very adaptable to city heat and pollutants. Regular watering (don’t drown it!) increases the growth rate. Bur Oaks are drought tolerant, low water-demand trees, once established. They have few insect or disease problems.
Hackberry (Celtis occidentalis) Balled & Burlaped, 50-100 lbs. - $43.00
The open appearance of this large broadly oval tree results from widely spreading branches. It will reach a mature height of 50-60 feet and 30-35 feet in width. Medium to bright green foliage turns yellow-green in the fall. The bark on a mature tree is corky. The “berries” on this tree are flavored like dates and relished by birds.
Hackberry trees can grow in wet to very dry areas, but do need water to get established. The Hackberry is a low water use tree. Some cities plant Hackberries to replace American Elms because they are hardy and disease resistant. It is hardy in all areas and in all soils, including difficult alkaline soil conditions. The leaves can be disfigured by nipple-galls, small bullet-like growths on the underside of the leaves caused by psyllid insects. Galls do not affect the growth or health of the tree.
Kentucky Coffeetree (Gymnocladus dioicus) Balled & Burlapped, 50-100 lbs. - $43.00
This unusual tree goes through a transition of textures, very light, graceful and airy in foliage (making it a good alternative to the Honeylocust), changing to a stark, very coarse picturesque tree in winter. Kentucky Coffeetrees greatly increase in beauty with age, starting out looking very stick-like. At maturity, it is 45-50 feet tall and 30-35 feet wide. The compound leaves with pointed leaflets 1 1/2” long emerge in late spring with new leaves tinged pink to purplish, gradually changing to dark green almost bluish green in summer, and then yellow in fall.
The brown pods are 5-10” long in the fall and hang on in the winter, giving the tree an even more interesting winter appearance. Early settlers made coffee from the pods. They tolerate higher alkaline soils and low water use, once established, and do very well in Colorado. Kentucky Coffeetrees have no serious disease or insect problems.
Northern Catalpa (Catalpa speciosa) Balled & Burlapped, 50- 100 lbs. - $43.00
This large tree (40-70’ tall and 20-40’ wide) grows fairly quickly to an upright and distinct shape that provides interesting winter character. Its large leaves (6-12” long and 3-8” wide) are bright green in summer, turning yellow-green to brown but often falling before turning. Its showy, large white flowers (orange and purple spots on insides) appear in May to June followed by seedpods 8-16” long that persist into fall and winter. This tree should be pruned for strong branches because its wood is brittle and can break in early or late snowstorms or high winds.
The Northern Catalpa tolerates different soil types and handles alkaline soil and drought well. It has few insect and disease problems.
Ruby Red Horsechestnut (Aesculus x carnea ‘Briotii’)Balled & Burlaped,50-100 lbs.-$43.00 This tree has very large, dark green leaves composed of five to seven leaflets. It will ultimately reach a mature height of and spread of 35 to 50 feet, but grows slowly. Pyramidal in shape when young, this Horsechestnut develops slowly into a round, very dense shade tree by five to seven years of age. It is outstanding in the springtime for its display of scarlet flowers. It has no appreciable fall color. This cultivar produces no seedpods. It makes an excellent speciman planting and is ideally suited for urban planting.
Ruby Red Horsechestnuts will grow in full sun or light shade and will tolerant a variety of soil types. No pests or diseases are of major concern.
Skyline Honeylocust (Gleditcia triacanthosinermis’Skycole’) Bare Root - $40.00
One of the very best varieties of thomless honeylocust, Skyline develops a more upright growth habit. Expect it to mature at about 40’ tall and 30’ wide. Small dark green leaflets cast a filtered shade that allows grass growth underneath. Some seedpods may develop in years with favorable weather conditions. Skyline leaflets develop a bright golden yellow fall color.
It is relatively tolerant of alkaline soils and drought, once established. Subject to trunk cankers when stressed and to spider mites with drought-stressed. There are several insects that can damage the foliage; these usually do not affect tree health adversely.
Small Trees — Good for planting under overhead power lines
Cleveland Select Pear (Pyrus calIeryana Cleveland Select’) Balled & Burlaped, 50-100 lbs.- $43.00 This thornless, narrow, upright-pyramidal tree has a compact form that makes it a good small area tree. It reaches a height of 30’ and width of 15’. It has numerous white flowers in the spring. Its glossy green summer foliage turns reddish-purple in the fall. Fruit is small, (1/4” diameter); birds may eat in fall.
The Cleveland Select Pear hardens off early, compared to other pears, making it less susceptible to early freezes. It is fireblight resistance.
Eastern Redbud (Cercis canadensis) Balled & Burlapped, 50-100 lbs.- $43.00
This single or multi-stemmed tree (20-30’ height and 25-35’ width) has a picturesque, rounded shape and cinnamon-orange bark upon maturity. It has reddish-purple buds followed by rosy pink pea-like blooms that appear along its branches before heart-shaped leaves emerge. In autumn, leaves turn yellow-green and papery 2-3” brown pea-like pods appear.
The Redbud will not tolerate poorly drained sites or heavy clay soils. The Redbud is an excellent tree for limited space and will thrive in a somewhat protected location. Leafcutter bee damage can occur on leaves but it does not hurt the tree.
Frontier Elm (Ulmus x ‘Frontier’) Bare Root - $35.00
This is an upright-pyramidal tree with a symmetrical shape that becomes 25’ height and 15’ width. In fall, its leaves turn a burgundy color. It is an excellent moderately-sized tree for use under power lines, along parking areas and highways, and in landscape plantings.
The Frontier Elm is a hybrid elm, which has a high level of disease tolerance to the fungus that causes Dutch elm disease and moderate resistance to elm leaf beetle.
Japanese Tree Lilac (Syringa reticulata) Bare Root - $25.00
This rounded, sturdy, upright small tree reaches 20’ in height and 12-20’ wide. Its compact, dense form, with ascending branches, makes it suitable for small spaces. The leaves are dark green in summer but have no fall color. 5-6” clusters of creamy white flowers appear in late June to early July, after the tree has leaved out. The flowers are not as fragrant as those on the shrub form. This tree flowers at a young age.
The Japanese Tree Lilac is adaptable to many soil types and compaction, and will tolerate alkaline soils. They prefer well-drained soil and full sun for best flowering. They are listed as moderately-low water use trees.
Serviceberry ‘Robin Hill’ (Amelanchier ’Robin Hill’) Balled & Burlapped, 50-100 lbs. - $43.00
This small tree may reach about 25 feet high and 12 feet wide, with an open, upright oval form. It has pink flower buds opening to white flowers in spring. Small red to purple-black fruit in June-July is very attractive to birds, particularly robins. The foliage is medium to dark green, changing to yellow-orange-red in the fall.
The Serviceberry is tolerant of many soil types. It rarely requires pruning, but may develop some suckers or shoots low on the trunk. It is considered a low to moderate water demand tree.
Spring Snow Crabapple (Malus ’Spring Snow’) Bare Root - $25.00
This dense upright oval variety of crabapple will reach 20’ in height and width. It blooms between mid-April and mid-May with large fragrant white flowers that last 3-4 weeks depending on weather. This crabapple is sterile so it does not produce fruit mess around sidewalks and high-use areas in the fall. Its bright green summer foliage turns yellow in the fall.
It is susceptible to fireblight and rust. It should be planted in areas with full sunlight. All crabapples are considered low water demand trees.
