Rethinking Plant Choices: Native, Adapted, and Climate-Wise for Colorado Landscapes
Foxtail Lilies at Denver Botanic Garden
When designing resilient gardens in Colorado, many people default to using only native plants. While native species are essential, Colorado’s changing climate demands a broader, more adaptive approach. At FireWise Botanical Garden, we champion a blend of native, adapted, and climate-analog plants to create low-water, fire-resistant, and beautiful landscapes that thrive across the Front Range.
Why Native-Only Planting Isn’t Always Ideal in Colorado
Native plants support biodiversity, water conservation, and pollinators. However, the term “native” can be limiting or even misleading. What’s considered native in Boulder may not be appropriate Denver. And some native plants can struggle in the harsh, erratic conditions of modern Colorado gardens.
Strict native-only planting doesn’t always result in healthy, resilient, or firewise landscapes. That’s where climate-adapted and drought-tolerant plants come in—offering diversity, function, and resilience.
What Are Adapted and Climate-Analog Plants?
Adapted plants are non-native species that have proven their performance over decades in Colorado gardens. They handle extremes—drought, hail, freeze-thaw cycles, and high UV—without becoming invasive.
Climate-analog plants come from regions with similar environmental conditions, such as Central Asia, the Mediterranean, or the Southwestern U.S. These plants are especially valuable in designing climate-resilient landscapes for Colorado's future.
Examples include:
Allium karataviense (ornamental onion from Central Asia)
Eremurus robustus (Foxtail Lily)
Agave utahensis (cold-hardy agave)
Cold-hardy cacti like Escobaria vivipara and Opuntia fragilis
These are excellent choices for low-water gardens, xeriscaping, and firewise zones—especially in Boulder County and other fire-prone communities.
Non-Native Doesn’t Mean Invasive
There’s a big difference between non-native and invasive. Many adapted plants are non-invasive, safe for ecosystems, and essential for expanding our plant palette in the face of climate change.
Using a mix of native and adapted plants can:
Reduce water use
Increase fire resistance in the defensible landscape zones (0–5 ft, 5–30 ft, 30–100 ft)
Support pollinators and wildlife
Create long-lasting beauty and seasonal interest
Help restore ecosystem function in urbanized areas
Yes—Non-Native Plants Can Benefit Pollinators, Too
Pollinators aren’t always picky. Many non-native plants—especially those from climate-analog regions—offer rich nectar and pollen sources throughout the growing season. Plants like Lavandula (lavender), Salvia greggii (autumn sage), Perovskia atriplicifolia (Russian sage), and Echinops (globe thistle) are magnets for bees, butterflies, and hummingbirds in Colorado gardens.
These plants can extend bloom periods beyond the window of many natives, providing food sources in early spring and late fall when native options are limited. In a firewise or water-wise garden, blending native and non-native pollinator plants is both practical and ecologically beneficial.
Firewise Landscapes Should Be Climate-Wise, Too
At FireWise Botanical Garden, we advocate for a balanced and thoughtful approach to landscape design:
Native plants where appropriate
Adapted and climate-analog plants where effective
A focus on right plant, right place, right purpose
This strategy allows us to build landscapes that are not only beautiful and biodiverse but also more resilient to wildfire, drought, and extreme weather—challenges we face more often in Colorado’s changing climate.
