Just as we long for a bit of green in midwinter and put an evergreen up inside for Christmas, we also want to see that bit of green outside all winter when shades of brown and straw dominate the landscape. Given our wind, dry climate and soil types, here are some reliable beauties for your yard.
Siberlocke Korean Fir (Abies koreana 'Hortsmann's Siberlocke')
New! This strikingly beautiful fir tree comes from the mountains of Korea. We first saw this tree several years ago at a high elevation residence in Casper's south side and it stopped us in our tracks! We've been looking for it ever since and we found it available from our grower! It features dark green (soft) needles that are recurved back to show bright, silvery white undersides, making the irregular branches appear to glow! As the tree ages, it produces eye-catching steel blue to violet cones that sit on top of the branches. Skip this tree if you want a fast growing tree (averages about 2 - 4 inches of growth per year). Yet, if you are looking for a speciman evergreen tree, you will be rewarded with this one. Must have good draining soils, water logged clay soils will kill this tree. Zone 5 in the literature, Casper experience suggests zone 4.
Available in July.

Austrian Pine (Pinus nigra)
Austrian Pine is natively found in western Europe extending to Asia Minor and named for the country of Austria, a cousin to our native Ponderosa Pine, except it has denser foliage which makes it a champion in the windbreak or as a large screen. early in it's life, the Austrian Pine will have branching right to the ground as it matures it will loose these branches exposing the thick plated brown bark. Tolerant of most soil types except soggy clay.

Bird's Nest Spruce
(Picea abies 'Nidiformis')
New! It may not be new to the trade but we couldn't pass up this beautiful dwarf spruce for our customers. It is slow growing, dense, yet broad with light green needles on spreading branches rising up slightly with nodding tips. A perfect evergreen for the rock garden or specimen use. Will do best if it's shaded in the hottest part of the day.
This has its origins from the North Dakota Badlands, a dry windy exposed setting, making it one of the most hardy ground cover junipers on the market today.It has beautiful dark green to blue-gray foliage with blue cones.A perfect addition near drive way entrances, you never have to prune to see over the top. It is good along patios and a way to step down from higher perennial plantings.

Blue Prince Juniper
(Juniperus horizontalis 'Blue Prince')
New! This one hales from the windswept praires of Alberta, Canada. This horizontal juniper only gets six inches tall with a spread of five feet making it ideal to drape over timbers and rock walls. The standout feature besides being extrordinarly rugged is the intense blue hue it has to its's needles that really comes into play in the winter garden. One could find many uses for such a carefree shrub! Tolerant of most soils so long as they drain well. Can be grown in clay so long as its kept on the dry side.

Douglas Fir
(Psuedotsuga menziesii)
New! This is a Wyoming native found at mid elevations in our mountains. Prized as a Christmas tree because of it's soft dark green needles, woodsy fragrance and classic pyramid form we've come to associate with evergreen trees. The literature is quite emphatic that this is a tree that needs consistent moisture in the soil but our experience in Wyoming suggests it can handle long periods of dry conditions after it gets established. Vastly underutilized! One of the largest evergreens on the market, but will probably take a lifetime to get to mature heights.

Killed by Kindness
Unfortunately conifers can actually drown when over watered. Clay soils do not allow water to drain off and roots are cut off from oxygen that they require. Pines are particularly at risk of drowning if planted in soil that does not drain or low spots with standing water. For tight clay in hot sunny and windy sites the Junipers are good choices. Wichita Blue, Table Top Blue Juniper are your best selections for extreme wind conditions and in clay soils. Follow our guide on watering for establishment and pay extra attention to be sure that the tree or shrub is not standing in water before more water is applied.
Fat Albert Spruce (Picea pungens)
An outstanding blue form with a naturally straight central leader and strong apical dominance giving it a reliable, well shaped form.

Sky High Juniper (Juniperus scopulorum 'Bailigh')
New! This is a naturally occuring columnar rocky mountain juniper with its heritage from the wind swept prairie of North Dakota! Just as hardy as the woodward juniper we offer, except it has a silvery blue appearance to its needles. This Juniper will work great as a beautiful visual screen, as a hedge or as an accent plant in a tight place. No pruning will be needed to keep its columnar form. Tolerant of most soils including clay if kept on the dry side. Very drought tolerant once established!
Available in mid-summer.

Table Top Juniper (Juniperus Scopulorum ‘Table Top Blue’)
Upright, yet spreading and flat-topped (now that’s an oxymoron!). Foliage is the soft-scale type (not prickly like common pfitzer) bright blue-gray in color. Handles wind and when established, drought too! This native sport is not an imported disease and damage–prone selection. This is a big bold statement of a shrub perfect on a slope or for privacy without blocking out the sky like a tree. Windbreak and screen.

Establishment
Establishment is the time frame during which a plant is spreading its root system and becoming balanced in the ability of top and roots to support each other. A one gallon container grown plant will take about a year to establish. Woody shrub plants in a 3-to 5-gallon container may need two years to become truly established. Container-grown trees follow a rule of thumb of one year for transplanting and an additional year for each inch of trunk diameter.
Vanderwolf’s Pine (Pinus flexis ‘Vanderwolf’)
A distinctive, densely branched pyramidal selection of our native limber pine.Its branches display long twisting blue-green needles with a light blue line on the undersides, very pleasing visually. This is a great replacement tree forColorado Blue Spruce. Like other pines, it will not perform well in slow to drain heavy soils.

White Fir
(Abies concolor)
New! This is a native to our neighbors mountains to the West (Utah) and South (Colorado). This is an evergreen tree that is vastly underutilized in the landscape. It has the appearance of a Blue Spruce but is more drought and wind tolerant! Unlike spruce, the white fir has soft flat needles that won't poke you - an added bonus should you happen to run into it when mowing the lawn or hanging Christmas lights. The needles are a blue/silvery color making for a great contrast in the landscape. Like all evergreens, White Fir likes well draining soils, it will perform in clay provided its kept on the dry side.

Wichita Blue Juniper - Spiral Form
(Juniperius scoplulorum 'Wichita Blue')
New! This is the same wichita blue juniper we carry, except it is in spiral form for use as a speciman tree! Usually these trees cost at least 50% more because of the increased management ie., pruning to get it in this form, but our grower reduced the cost and we jumped on them!
This is a selection made at the Cheyenne Experimental Station that has never been widely available in the trade. Very columnar, but unlike many forms does not exhibit the typical muti-leader type growth indicative of columnar forms of juniper. Branches tend to develop witches' broom-type growth.

Winter Watering
Even though we consider the evergreens to be some of the toughest plants, they are not totally dormant in winter and continue to lose moisture through their needles year round. For establishment purposes we recommend watering new plants monthly in dry open winters. Water established plants once or twice a winter depending on soil moisture and temperature. Our water is hard, focus your attention on the roots and not on the foliage! Newly planted deciduous trees and shrubs should be watered once or twice a winter.
Rain Gauge
Throughout this site, the following are used as guidelines for watering established plants:
These plants need regular watering somewhat like a bluegrass lawn so that they never dry to depth in the root system during the active growing season and need occasional winter watering to prevent root dessication and resultant plant death.
These plants are adapted to intermittent deep watering with soil drying to a depth of a few inches between waterings. Watering frequency may be every couple of weeks during the active growing season and maybe only one winter watering for optimal care.
These truly xeric plants can live with our 12 inches of natural precipitation and only need a winter watering during a multi-year drought but they will thrive with a monthly watering. Overwatering will kill some of these.
