Small to Spreading Shrubs These shrubs are wonderful accents that fit on all sizes of properties and are vital on the new small lots of many new homes/ town houses. Their natural size and form means that you won’t spend your time pruning to keep them inbounds. They have a full range of character, foliage texture and colors, many bloom and not just in the spring. Outstanding autumn colors and exposed winter form provide interest in our quiet season. They are also good as anchors for perennial flower beds.
was developed at the U. of Nebraska and is the most dwarf specie of its kind! With a mature height of only 3’ this lilac with light pink flowers can be planted in tight places where other lilacs could not fit. If you love lilacs but have space limitations –plant this one! Great drought tolerance after establishment. Height: 3’ W: 2.5” Zone 2
the hardiest of all the Spireas and you guessed it - a survivor of the Cheyenne Horticulture Field Station! This selection produces profuse clusters of pure white flowers in May against small dark green leaves more compact than traditional spireas. The parent plant continues to thrive after 50 years! This is a great shrub for an informal hedge or as a foundation planting near the front porch—a classic old fashion plant. Height: 3’- 5’ Width: 3’ – 5’ Zone 3
Darker graygreen foliage and darker violet flowers differentiate Dark Knight from Blue Mist. In late summer these shrubs provide a vivid display of flowers that is simply exceptional! They may die back in winter so prune to the ground each spring -- it’s ok, flowers are borne on new wood. A favorite of bees, so avoid placement near entry ways. Excellent drought tolerance for this Mongolia native.
Zone 4
This compact shrub opens its leaflets similar to mountain ash but in orange that mature to green and are topped by elongate panicles of creamy white flowers in later summer. Height 3’ Width: 3’ Shape: Broad upright
Zone 2
New! Hardy Hibiscus Hardy Hibiscus form rounded shrubs bearing huge hummingbird attracting flowers in later summer that put hollyhocks to shame. They break dormancy later in spring thus avoiding freeze damage to buds. Plant them in Sun 3” deeper than potted to provide extra winter protection and to encourage more branching. Shape: Rounded The regular watering SSS of a bluegrass lawn setting matches their needs for best flower production. Zone 4.
Through the years we have seen a few hardy pink hibiscus planted in Wyoming. But the new brighter colored ones were planted amongst ornamental grasses in the ground and in big planters around Ft. Collins and the late summer effect was wonderful! Now we have a supply to offer for your garden. These look like the florists’ pot plants with big vibrant blooms but they can survive a Zone 4 winter. Provide regular garden watering (also winter water to prevent root desiccation) and plant in sun. They look great with Purple Fountain Grass! Hummingbirds will thank you and you will have a bit of tropical looking WOW power. At 20-30” tall and 24” wide these will stay more out of the wind both summer and winter than the original cultivar thus performing acceptably in our conditions. These break dormancy late, thus avoiding spring frost damage and you may plant 3” deeper to provide more winter protection to new buds that will become branches.
Vigorous Bluebird selection, long blooming with large, intense deep pink flowers and leaves that are the size, color and shape of Norway Maple. 4-5’Height: 4-5' Width: 3'
Its low spreading form and fast growth rate make this plant excellent for mass plantings as a groundcover, or for erosion control. Stunning autumn color turning brilliant scarlet to orange! This one can handle most Wyoming soils and weather!
A prostrate form of R. trilobata which forms a dense groundcover and will cascade over walls! Much more ground hugging than Gro Low and hardier! Summer foliage like the species but autumn color is amber to brick red. This cultivar was found growing over limestone outcroppings so you know its alkalinity tolerance is as good as the species. Consider this one with groundcover Juniper for textural and color interest!
Nitrogen fixing native western prairie shrub with 3-4” spikes of blue-purple flowers in midsummer. Arching stems with finely pinnate compound leaves composed of small gray-green leaflets form a 3-4’ tall and wide shrub with open spreading habit. When in bloom this is one of the more showy western plants. Plant in sun and relatively dry soil.
Really BIG rocks are a natural part of the arid western environment and using them in created landscapes ties your property to its surroundings reinforcing a western sense of place. To make your landscape element look right be sure to sink the big rock into the ground enough to look natural. Bury it up to a third or more and add mid sized and smaller rocks along one side as if they were caught there during erosion or stream flow. Now you have planting micro-climates: a cool north side where reflected heat won’t be a problem so sensitive plants won’t break dormancy at the wrong time of year if planted there and a nicely warm south side for those heat lovers.
