OUR TREES FOR SPRING 2020
Tree species selection is subject to guidelines and subject to change, dependent on availability. Tree requirements and maintenance for all newly planted trees can be found in our Terms and Conditions.
SKYLINE HONEYLOCUST-
Gleditsia triacanthos var. inermis ‘Skycole’
Honeylocust (Gleditsia triacanthos f. inermis ‘Skycole’ Skyline®) is a tough, medium-sized flowering tree that casts a light shade that won’t kill lawn grasses. It typically grows 60–80 feet tall with a rounded spreading crown. Inconspicuous, greenish yellow to greenish white flowers appear in racemes in late spring. Flowers are followed by long, twisted, and flattened, dark purplish-brown seedpods (to 18 inches long) that mature in late summer and persist well into winter. Seedpods contain, in addition to seeds, a sweet gummy substance that gives honey locust its common name. Skyline® is a thornless variety with a stronger upright growth form, few seed pods, and excellent yellow fall color. This is an adaptable tree especially good for streets and parking lots. It is perfect for people who prefer very little leaf litter in the fall, and is available for planting locations without overhead powerlines.
GLENLEVEN LINDEN –
Tilia cordata ‘Glenleven’
Glenleven Littleleaf Linden is a great choice for those with a tree lawn less than six feet wide, and no overhead lines. It’s compact form of 40′ tall and 30′ spread still provides plenty of shade. It has a pyramidal form with dark green foliage in summer and gold fall color. A prolific bloomer with small fragrant flowers in the Summer. Also a bee attractant.
BUR OAK-
Quercus macrocarpa
The Bur Oak is adaptable to various soils and it does well in the alkaline soils prevalent to the Cheyenne area. The leaf has a dark green luster above, with a light greenish or greyish, somewhat hairy surface below, with yellow and brown fall color. The dark grey bark is very corky and deeply ridged; even on the young trees it appears old. The fruit is a solitary nut that is halfway enclosed on the top end, in a cup-like structure. This tree is slow growing, which creates a strong, storm resistant tree which produces significant shade at maturity.Bur Oak is among the toughest and hardiest of all the oaks, which is saying a lot. In Cheyenne, it will reach a mature height and spread of 50′ – 60′, so is available for a large space without overhead powerlines.
ACCOLADE ELM-
Ulmus ‘Morton’
ACCOLADE is a vase shaped, medium to large, deciduous elm that typically grows to 50-60′ tall and to 25-40′ wide. It reportedly has excellent resistance to Dutch elm disease, elm leaf miner and elm leaf beetle. In addition to its excellent disease and pest resistance, it is also noted for its vigorous growth, glossy dark green foliage and good yellow fall color. Non-showy, small green flowers appear in spring before the foliage emerges. Flowers give way to single-seeded, wafer-like samaras (each tiny seed is surrounded by a flattened oval-rounded papery wing). Seeds mature in April-May as the leaves reach full size. Glossy, ovate-elliptic, dark green leaves have toothed margins and asymetrical bases. Leaves typically turn a quality shade of yellow in fall. The fastest growing tree we offer
NORTHERN RED OAK
Quercus rubra
Northern red oak is native to the Midwest and is one of the faster growing oaks for the home landscape. The leaves are handsome throughout the year, emerging pinkish-red, turning lustrous dark green in summer, and changing to russet-red to bright red in autumn. Its tolerance of salt and air pollution makes it a good tree for more exposed areas.
SARGENT STRAIGHT COTTONWOOD
Populus sargentii ‘Jeronimus’
Selected for its more uniform upright
growth and branch habit, this male form
of Sargent Cottonwood grows well in the
western plains states. Distinctly upright
in younger years, trees can become more
rounded with age. Triangle-shaped light
green leaves are rather glossy and remain
clean through the growing season. Older
trees develop a thick rough bark.
STATE STREET MAPLE-
Acer miyabei ‘Morton’
STATE STREET is noted for its attractive upright rounded growth habit, symmetrical branching, crisp green leaves, and quality yellow fall color. Five-lobed, palmately-veined, flat to semi-glossy, dark green leaves (each to 3-5” long) have acuminate, bluntly dentate leaf lobes with deep sinuses. Leaves retain good green color into October before turning pale to rich yellow. Leaf stalks contain a milky sap. Ornamentally insignificant yellow-green flowers in erect, 10-15 flowered corymbs bloom in spring (April-May) as the new leaves are beginning to develop. Flowers give way to two-winged samaras (each samara to 1” long) with wings spreading to 180 degrees. Rough corky gray-brown bark develops attractive orange-brown fissures with age, eventually becoming scaly with fluting.
JAPANESE TREE LILAC
Syringa reticulata
Japanese tree lilac is larger than the shrub lilacs and it blooms a little later. It produces large clusters of small creamy-white, fragrant flowers. This is a low growing ornamental suitable for planting under power lines.
THORNLESS COCKSPUR HAWTHORNE
Crataegus crus-galli var. inermis
This variety of cockspur hawthorn has thornless stems. It displays beautiful white flowers in spring and persistent fruit in fall and winter. This is a low growing ornamental suitable for planting under power lines.
