Choosing Shrubs for Colorado Conditions
Flowering shrubs can provide structure, screening, seasonal color, erosion control, and wildlife habitat without requiring the water or maintenance associated with a conventional lawn. The challenge is selecting plants that fit both the site and the long-term landscape design.
A shrub should be evaluated by its mature width and height, sunlight requirements, cold tolerance, soil preference, water needs, growth habit, and placement near buildings, walkways, fences, and irrigation zones.
The term native also requires context. A plant may be native to Colorado but naturally occur at a different elevation, in a wetter habitat, or in soil unlike the planting site. Native status alone does not guarantee success.
Before Selecting a Shrub
Measure the usable width and height. Account for windows, roof overhangs, walkways, utilities, fences, and neighboring plants. Avoid choosing a six-foot-wide shrub for a narrow two-foot foundation bed.
Observe the area during the growing season. Reflected heat from south- and west-facing walls can create much harsher conditions than the general sun exposure suggests.
Group plants with similar watering needs. A drought-tolerant shrub placed in the same irrigation zone as lawn or moisture-loving perennials may receive excessive water.
Many Colorado sites contain compacted or alkaline soil. Drainage, root-zone preparation, and correct planting depth often matter more than adding large amounts of amendment.
Decide whether the shrub is intended for screening, flowers, erosion control, habitat, foundation planting, winter interest, or a low-water ornamental bed.
Recommended Flowering Shrubs
Apache Plume
Fallugia paradoxa
- Height
- 4–6 feet
- Width
- 4–6 feet
- Sun
- Full sun
- Water
- Low
- Bloom
- Late spring through summer
Apache plume produces white, rose-like flowers followed by distinctive feathery pink seed heads. It performs well in sunny, dry locations with good drainage and works effectively in naturalistic beds, slopes, and water-wise landscapes.
Give it enough room to develop its loose, irregular form. It is generally better suited to informal planting than tightly clipped foundation beds.
Mountain Mahogany
Cercocarpus montanus
- Height
- 6–12 feet
- Width
- 6–10 feet
- Sun
- Full sun to light shade
- Water
- Very low
- Bloom
- Spring
Mountain mahogany is a durable native shrub with small flowers followed by curled, feathery seed tails. Its dense branching can provide screening, structure, wildlife value, and year-round texture.
It is best placed where its eventual size is an advantage. Frequent shearing can destroy its natural form and create unnecessary maintenance.
Golden Currant
Ribes aureum
- Height
- 4–7 feet
- Width
- 4–7 feet
- Sun
- Sun to partial shade
- Water
- Low to moderate
- Bloom
- Spring
Golden currant produces fragrant yellow flowers in spring followed by dark edible berries when pollination and growing conditions are suitable. It can tolerate a range of light conditions and is useful in mixed borders, wildlife gardens, and informal screens.
It may spread by suckering, so allow room for a colony-forming habit or manage new shoots where a tighter footprint is required.
Wax Currant
Ribes cereum
- Height
- 3–6 feet
- Width
- 3–5 feet
- Sun
- Sun to partial shade
- Water
- Low
- Bloom
- Spring
Wax currant has small pinkish-white tubular flowers, rounded leaves, and translucent berries. It fits well in foothill-inspired landscapes and can tolerate drier sites once established.
Afternoon protection may be beneficial in especially hot, reflected locations, depending on elevation and irrigation.
Shrubby Cinquefoil
Dasiphora fruticosa
- Height
- 2–4 feet
- Width
- 2–4 feet
- Sun
- Full sun
- Water
- Low to moderate
- Bloom
- Late spring through fall
Shrubby cinquefoil provides a long flowering season and a compact growth habit. Yellow-flowered forms are common, while cultivated selections may offer white, pink, or orange flowers.
It works well along walkways, in mixed shrub beds, and where a smaller flowering shrub is needed. Avoid excessive water and heavy shearing.
Rabbitbrush
Ericameria nauseosa
- Height
- 3–6 feet
- Width
- 3–6 feet
- Sun
- Full sun
- Water
- Very low
- Bloom
- Late summer through fall
Rabbitbrush produces bright yellow flowers late in the season when many other plants have stopped blooming. It performs especially well in dry, exposed areas and supports pollinators.
Its informal form and late-season seed production make it better suited to naturalistic or xeric landscapes than highly manicured beds.
New Mexico Privet
Forestiera neomexicana
- Height
- 8–15 feet
- Width
- 6–10 feet
- Sun
- Full sun to partial shade
- Water
- Low
- Bloom
- Early spring
New Mexico privet is a large, durable shrub or small multi-stem tree. Its small early flowers are followed by blue-black fruit on female plants when a compatible male plant is nearby.
It is useful for screening, wind protection, habitat, and larger property borders. Confirm adequate space before planting near structures.
Western Sand Cherry
Prunus pumila var. besseyi
- Height
- 3–6 feet
- Width
- 4–6 feet
- Sun
- Full sun
- Water
- Low to moderate
- Bloom
- Spring
Western sand cherry produces white spring flowers followed by dark fruit. It prefers well-drained soil and can serve as a medium-sized accent or informal hedge.
Cultivated purple-leaf forms are widely sold, but not every ornamental cultivar should be treated as equivalent to the native regional form.
Quick Selection Guide
| Landscape need | Strong candidates | Important consideration |
|---|---|---|
| Very low water use | Rabbitbrush, mountain mahogany, Apache plume | Establishment watering is still required |
| Long flowering season | Shrubby cinquefoil | Performs best with adequate sunlight |
| Informal screening | Mountain mahogany, New Mexico privet, golden currant | Allow for mature width and height |
| Partial-shade tolerance | Golden currant, wax currant | Flowering may be reduced in deeper shade |
| Late-season color | Rabbitbrush | Natural form can appear loose or irregular |
| Wildlife-oriented planting | Golden currant, mountain mahogany, rabbitbrush | Fruit and seed may increase bird activity |
| Smaller foundation bed | Shrubby cinquefoil | Avoid overwatering and constant shearing |
Native Does Not Mean Maintenance-Free
Native and regionally adapted shrubs still require correct installation and establishment care.
- Dig a planting hole wider than the root ball but no deeper than the root flare.
- Correct circling roots before planting.
- Keep the root flare visible rather than burying the trunk.
- Water deeply during establishment instead of relying on light surface watering.
- Use mulch to moderate soil temperature, but keep it away from the stems.
- Separate low-water shrubs from lawn irrigation whenever practical.
- Plan for mature size rather than pruning continuously to compensate for poor placement.
Irrigation Considerations
New shrubs require regular establishment watering even when they will eventually be drought tolerant. The root ball and surrounding soil must both receive water during the first growing seasons.
Drip emitters should be positioned around the active root zone rather than directly against the trunk. As the shrub grows, emitters may need to be moved outward or added to encourage broader root development.
Plants to Place Carefully
Some excellent shrubs become maintenance problems when installed in the wrong location.
- Large shrubs placed beneath windows or roof overhangs
- Suckering shrubs installed in narrow formal beds
- Rabbitbrush placed beside frequently used walkways
- Thorny or rigid plants positioned near play areas
- Low-water shrubs connected to high-frequency lawn irrigation
- Plants selected without considering deer or rabbit browsing
- Shrubs planted directly over utility corridors or irrigation valves
