TREES
Abies concolor WHITE
FIR
A native Colorado
evergreen with silvery blue-green leaves. 80' tall at maturity. Grows about
6" a year for the first few years then 12" per year. One of the most
beautiful and easy to grow evergreens. Zone 4.
Abies equi-trojani
TROJAN FIR
Discovered on the
slope of Mount Gargarus, the highest mountains of the Kaz-Dagh (Mount Ida,
Turkey). 75' tall at maturity. Zone 5.
Acer ginnala
'Cheyenne' MAPLE, CHEYENNE
This is a superior
selection of the ginnala maple, from a Cheyenne, Wyoming source. Selected for
brilliant orange to red fall leaf color, robust vigorous growth, salt and cold
tolerance. 25' tall. Zone 3.
Acer grandidentatum
MAPLE, BIGTOOTH
Native to most of the
West, this maple has lovely fall color. 40' tall at maturity. Slow growing when
young. Zone 3.
Acer monspessulanum
MAPLE, MONTPELIER
We're growing the
Montpellier Maple because it is one of a handful of maples that does well in
alkaline soils. Another reason to grow it in Colorado: it likes sunny and dry
locations. Its glossy, dark green, leathery leaves are made up of three rounded
lobes. The leaf is only about 1-2" long. It has red-winged fruits in
mid-summer.
Its small leaves and
tolerance of dry soil makes it a good choice for bonsai. 15-25' tall at
maturity. Zone 5.
NEW! Acer tataricum HOT WINGS MAPLE, HOT WINGS
The habit is graceful, upright and spreading. The little
yellow flowers are followed by bright red samaras, hence the name Hot Wings.
The dark green foliage turns yellow to red for good fall color. Tolerant of
alkalinity and dry conditions. Plant Select. 15�-20� tall. Zone 3.
Acer truncatum MAPLE,
SHANTUNG
The new leaves emerge
reddish-purple in spring and then turn glossy dark green. Fall color can be
combinations of yellow, orange, and red. Drought and heat tolerant. Hardy to
zone 4.
Albizia julibrissin
MIMOSA
Also known as silk
tree because the pink thread-like flowers resemble strands of silk. The small
compound leaves and feathery flowers give this a tropical appearance. Zone
hardiness is yet to be determined. The seed parent for these trees is located
in Dighton, KS (Western Kansas, a little south of Colby). 20' tall.
Calocedrus decurrens
INCENSE CEDAR
This western native with
exfoliating red brown bark is moderate to fast growing. Drought-tolerant once
established, incense cedar prefers dry areas, full sun, and does well on
southwestern slopes. The seeds are eaten by songbirds. 35' tall at maturity.
Zone 5.
Celtis occidentalis
HACKBERRY
A moderate to rapid
grower similar to elm but better. This deep rooted tree withstands wind, heat,
drought and alkaline soils. A great shade tree for our area with a spreading
crown and red-orange fruit. 50' tall. Hardy to zone 2.
Cupressus arizonica
ARIZONA CYPRESS
This attractive
Southwestern native tree grows slowly under natural dry conditions, but it is a
rapid grower (up to 3 feet per year) in cultivation. Plant in spring to allow
the roots to establish before winter. Hardy to 5200' or possibly more. Zone?
Cupressus bakeri
BAKER�S CYPRESS
The northernmost and
hardiest New World cypress. Our seed comes from a tree growing at Denver
Botanic Gardens. Zone 5.
Gymnocladus dioica
KENTUCKY COFFEE TREE
This tree is adaptable
to many soil conditions, including alkaline. The long "coffee beans"
that gave it its common name are mahogany colored and decorative in the winter.
The doubly-compound leaves give a lacy appearance in summer. The genus name
means "naked branch", and after the leaves fall, the naked branches
give the tree a very
picturesque winter appearance. 50' tall. Zone 4.
Juglans nigra BLACK
WALNUT
This hardwood tree is
fast growing. In optimum sites it can grow 3'-4' per year. It likes regular
moisture during the growing season and needs full sun. 50' tall. Does not like
late spring frosts, so plant in area where cold drains away. Hardy to zone 4.
Pinus monticola
WESTERN WHITE PINE
A pyramidal tree, with
beautiful evergreen foliage The needles are about 3" long, slender, straight,
and soft to the touch. They are bluish-green in color with a white strip on the
back, and are found in bunches of five. 100' tall. Zone 5.
Populus idahoensis
IDAHO HYBRID POPLAR
Idaho Hybrid Poplar
grows rapidly, as much as 6 to 10 feet a year under irrigated conditions.
Discovered approximately 40 years ago, this variety is much better than other
poplars for our western growing conditions. Although it can survive drought,
for faster growth it needs adequate water. 40' tall. Zone 3.
Populus tremuloides
QUAKING ASPEN
A pioneer tree that
regrows from its roots after a forest fire, aspen trees are found at high
elevations in Colorado. The soft rustling of their leaves is one of nature's
loveliest sounds. The leaves are attached by flattened petioles (leaf stems),
joined at right angles to the leaf, so that they twist and flutter with the
slightest breeze. 40'-70' tall at maturity. They live 150 years, although some
colonies are much older. Zone 2.
Pseudotsuga menziesii
'Glauca' DOUGLAS FIR, ROCKY MOUNTAIN
This tree is common
through the west; it flourishes in higher elevations but is probably not the
tree for Pueblo. This is one of the fastest growing evergreens. Often used as a
Christmas tree because of its great form, color, and because it holds its
needles for such a long time. Zone 4.
Quercus gambellii
GAMBEL OAK
Our native oak.
Although called a "scrub" oak, its size varies from 5 foot shrubs to
50 foot trees, depending upon available moisture and deer browsing. With adequate
moisture, gambel oak can grow 2 feet per year. Here at Perennial Favorites we
have an oak that is 40' tall. Zone 5.
Quercus macrocarpa x
Rober BUR-ENGLISH OAK
Imagine this: a fast
growing oak! This hybrid of Burr Oak and Columnar English Oak can grow 2 to 4
feet a year once established and is adaptable to alkaline soils. The tree forms
a large open crown and produces a multitude of acorns annually. 50' or more
tall. Hardy to at least zone 4.
Quercus macrocarpus x
gambellii BUR-GAMBEL OAK
This hybrid between
Bur oak and Gambel oak combines the best of each of its parents: the cold
hardiness and fast growth of the bur oak, and the drought hardiness and acorn
production of the Gambel oak. Excellent red color in fall. Zone 4.
Sapindus drummondii WESTERN
SOAPBERRY
A North American
native, this tree grows in full sun or partial shade on a wide variety of
soils. It's very tolerant of wind, drought, and poor soils. Transplants easily,
too, and will establish with only minimal irrigation. The strong wood of this
tree make it a good choice to plant where severe winds are a given along the
front range.
25' tall. Hardy to
6500'.
Xanthoceras
sorbifolium POPCORN OR YELLOWHORN
This small tree has
many common names. Popcorn shrub is one of its names, referring to the clusters
of white flowers in the spring, Yellowhorn refers to the horn-like
protuberances between the flowers. 20' tall at maturity. Drought tolerant once
established. Plant Select. Zone 5.
