The Perfect Plant for Colorado Landscapes

If I could create one perfect plant for the Pikes Peak region, what would it be like?

Of course, I’d want it to be attractive. It should adorn itself with cheerful spring flowers, good-looking foliage, and intense fall color. I’d add persistent fruit or berries to feed the birds and provide winter interest.

My perfect plant should be easy to grow; I’d want it to thrive in our native soils with little or no supplemental water. It must be hardy to at least 8,000 feet, and still handle summer heat waves.

I’d create a versatile plant that could be trained as either a medium-to-large shrub or small tree. Deer resistance would be a bonus. And I’d want it to be readily available from local garden centers (at a reasonable price).

Well, it seems that Somebody beat me to it. There is a perfect plant for this area—the common Chokecherry.

 

Quaking Aspen

Appearance
Stands of bright gold aspen (Populus tremuloides) shimmering in the sunlight are a spectacular sight, so it is no surprise that many people plant aspen in their home landscapes. Aspen are fast growing and relatively short-lived relatives of cottonwoods and poplars. Ranging from 40 – 65 feet tall, they have a smooth white trunk and bright green, heart-shaped leaves. Female trees produce 2-inch catkins that develop into tiny long, narrow cones.

 

Chocolate Flower

Berlandiera lyrata

Appearance: This very aromatic plant has bright green, flat spreading leaves with shallowly lobed edges.  The flowers are daisy-like, with green center and light yellow petals.  The underside of the petals have maroon markings on them.

Habitat: This plant is very drought tolerant and blooms profusely throughout the season.  The flowers have a wonderful chocolate scent are are edible.  Chocolate Flower prefers full sun and needs very little water.  Found on the Western plains to northern Mexico, in dry rocky soils.  Hardy to Zone 4.

 

Cowboy’s Delight

Sphaeralcea coccinea

Cowboy’s Delight

Sphaeralcea coccinea

Appearance: This small perennial appears to be a sweet little hollyhock. It grows to just over 12″ tall, and the silver-green, hairy leaves are each deeply lobed into three sections. Another variety found in cultivation, Sphaeralcea munruona is very similar, but with more gently lobed leaves. The wheel-shaped bright orange flowers are under an inch in diameter. Their bright appearance in often otherwise dull areas is what earned it its common name of cowboy’s delight. Blooming starts in June and continues through September.

Habitat: Cowboy’s delight thrives in sunny, open areas and can be found in both the plains and foothills.

 

Wild Iris

Iris missouriensis

Appearance: Wild Iris is a bluish-purple native flower characteristic in appearance to cultivated irises.  It grows to about 2 feet in height and blooms from May to July.

Habitat: It is found in foothills to subalpine life zones, mostly in moist open areas, wet meadows, and stream sides at 4,500 to 9,500 feet elevation.  Growing in full sun, it drenches meadows in its vivid blue color, and is prevalent in areas that have been grazed heavily.

 

Dwarf Pussytoes

Appearance: Dwarf Pussytoes has pretty white flowers clustered like a cat’s toes on stalks growing to 6 inches in height.  The lance-shaped leaves grow in low mats, so the combination of the leaves and flowers on stalks makes it ideal for use as a groundcover.

Habitat: One of nine species found in the southern Rockies, it is commonly found in open mountain and foothills areas in sandy, well-drained soils. It has low moisture requirements and grows in sun to part shade.

 

Boulder Raspberry

Appearance

With its ostentatious white flowers clamoring for your attention, Boulder Raspberry (Oreobatus deliciosus ) impresses like a hybridized cultivar, rather than a native shrub. Growing three to five feet tall and six feet wide, arching, sprawling stems carry bright green, lobed leaves that turn yellow in fall before dropping for the winter. Spring’s blooms develop into small reddish purple fruit resembling cultivated raspberries. While edible, the berries are generally considered unpalatable. However, they will attract birds and other wildlife. Unlike other raspberries, the stems are thornless.

Habitat

Dry shade is enough to send most plants running, but Boulder Raspberry thrives there. Long-lived and very hardy, you can find these shrubs on Rocky Mountain slopes and ravines between 4,500 and 9,000 feet. They prefer gravelly or silty soil with good drainage.

Landscape Suitability

A bit coarse for a formal garden, Boulder Raspberry combines well with other natives in a natural setting. It works best as an understory plant or in a northern exposure. Pink shrub roses (such as ‘Nearly Wild’) or purple-leafed ‘Diablo’ Ninebark (Physocarpus opulifolius) would make outstanding companions. For best results, situate plants in light to medium shade, and add two to three inches of compost to the soil. Water deeply but infrequently.

Poison Ivy

Toxicodendron rydbergii

Appearance: Poison Ivy is a member of the Sumac family and recognizable by its three shiny leaflets, white flowers in March to June, and smooth white berries later in the summer.  It grows to a mature height of 2 feet.

Habitat: Found in the plains and foothills, it grows on rocky slopes and at cliff bases in full sun to partial shade.

 

Golden Currant

Golden Currant (Ribes aureum)

Appearance

Aptly named Golden Currant blooms in early spring with showy clusters of small but fragrant bright yellow flowers. The blossoms are followed in summer by edible fruit that ripens from green through red to black. In autumn, green, lobed leaves turn to amber or scarlet before falling. The arching branches can reach anywhere from three to nine feet in height, depending on age and habitat.

 

Mariposa Lily

Mariposa Lily

Calochortus gunnisonii

Appearance: Blooming from March to June, this is one of the most beautiful, simplistic wildflowers of Colorado.  A close relative to lilies, the cup-shaped flowers of Mariposa Lily have 3 translucent petals, usually white with a tinge of pink or blue.  Inside the cup of petals is a ring of bright yellow hair.  This native perennial grows up to 20” tall on a single slender stem.  Narrow, grass-like foliage usually withers at the base of the plant by bloom time.
