Drought tolerance depends on where a shrub grows, how it is sited, and whether it has become established. Colorado foothill shrubs and low-desert Arizona shrubs are not interchangeable. The available regional guidance supports six specific candidates—not seven species that can responsibly be recommended across an unspecified region—so use the options below as starting points and confirm local suitability before planting.
Choose for your region and site first
Elevation, climate, soil moisture and drainage, mature size, and exposure all affect whether a shrub is a good fit. Colorado State University Extension organizes native shrub recommendations around factors including altitude or life zone, moisture, mature size, and evergreen status. Arizona Department of Water Resources offers location-specific low-water landscaping resources. A plant described as drought tolerant is not automatically suited to every dry garden.
The six species below are regional examples from Colorado and low- to mid-elevation Arizona guidance, not results from a nationwide comparison. Check a local extension or water-agency guide for your precise location, and verify the hardiness and mature size of the species or cultivar available from your nursery.
Three candidates for Colorado landscapes
Silvery leadplant (Amorpha canescens)
Colorado State University Extension lists silvery leadplant for the plains to foothills. It tolerates drought and poor soils, and its violet-purple summer flower spikes add seasonal color. Consider it for a compact native planting where those regional conditions fit; the cited information does not establish a specific mature height or spread here.

Rabbitbrush (Chrysothamnus nauseosus)
Rabbitbrush is listed for Colorado plains, foothills, and upper Sonoran settings. Its yellow flower clusters appear in late summer. Size and growth habit vary by subspecies, so identify the subspecies and check its mature dimensions before using it near a path, wall, or window.
Mountain mahogany (Cercocarpus montanus)
Colorado guidance places mountain mahogany in foothill to montane settings and describes its moisture needs as low to moderate. Its open growth habit and feathery seed heads can suit a naturalistic planting. Match it to the appropriate Colorado life zone rather than assuming that a plant for a cooler foothill site will suit a hot low desert.
Three candidates for low- and mid-elevation Arizona deserts
Creosote (Larrea tridentata)
Arizona Cooperative Extension includes creosote among shrubs for low- and mid-elevation desert landscapes. Its low-desert context matters: the cited pruning guide does not make it a general recommendation for cold or wet regions. It is listed among shrubs that require little or no regular pruning.
Jojoba (Simmondsia chinensis)
Jojoba is also included in the Arizona guide for low- and mid-elevation desert settings and is listed as requiring little or no regular pruning. Confirm that your site and local climate match that context before choosing it.

How to select the missing seventh shrub
The regional sources behind these examples do not establish a seventh species for one declared audience region, and the title does not identify a location. Rather than offer a plant that may be unsuitable, select the last candidate from a local extension or water-agency list. Compare the site and plant on these points:

- Climate and elevation: Does the local guide recommend it for your elevation, life zone, and winter conditions?
- Dimensions and purpose: What are its mature height and spread, and will it work as a screen, hedge, accent, or habitat planting?
- Light and soil: Does it fit the available sun, drainage, and moisture conditions?
- Seasonal character: Is it evergreen or deciduous, and when does it flower or produce fruit?
- Care: What establishment watering and pruning does the local guide specify?
These checks also apply to the six named shrubs. The available source summaries do not give a complete, consistent set of mature dimensions, sun exposure, evergreen status, or wildlife value for every species; consult a local plant profile for those details instead of inferring them from drought tolerance.

Drought tolerance does not mean a newly planted shrub can be left without water. Colorado State University Extension says newly planted native shrubs may need supplemental moisture; where a shrub is planted in its native environmental conditions, watering can be reduced or eliminated after establishment. That guidance is conditional on correct siting and should not be treated as a universal schedule for other regions or species.

Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →For Arizona landscapes, University of Arizona Cooperative Extension’s 2017 Watering Trees and Shrubs guidance recommends deep, infrequent watering at the drip line, where active absorption occurs. It describes the root zone as the soil reservoir for moisture and nutrients, notes that most shrub roots extend beyond the canopy, and gives 12–14 inches as a typical shrub root-zone depth. These are Arizona guidelines, not guarantees for every soil or plant.
Adjust irrigation to plant maturity, soil type, season, and weather. The Arizona guidance notes that hot, dry, windy conditions can increase water use and says established plants may adapt to slight drought between waterings after one or two years; that timing is guidance, not a promise for every shrub or site. During drought, the University of Arizona’s 2021 landscape-maintenance guidance recommends prioritizing trees and shrubs, especially structural shrubs such as hedges, and watering their root zones to appropriate depth while allowing some soil to dry between irrigations.
Pruning and placement
Pruning needs vary by species. Arizona Cooperative Extension’s low- and mid-elevation desert guidance lists some shrubs as requiring little or no regular pruning, while others need seasonal attention. Give each shrub room to reach its mature size, prune only when necessary and at the appropriate time, and use the plant’s natural form as a guide. Shearing is best reserved for formal hedges or plant sculptures, not applied automatically to every shrub. Sharp hand pruners are suitable for smaller stems; loppers are specified for thicker ones.
Correctly sited native shrubs can reduce external inputs, and Colorado State University Extension notes their habitat and biodiversity benefits in Colorado. Those benefits depend on choosing plants that fit the local environment, rather than treating a regional plant list as a universal one.
