How Do You Choose Indoor Plants Suited To Colorado’s Climate
Understand Colorado’s indoor climate challenges
Colorado residents think about climate in terms of elevation, sun, and dry air. Those same factors matter inside homes. Your indoor microclimate is shaped by the outdoor conditions (high UV, large temperature swings, low absolute humidity) and by how your house is heated, ventilated, and shaded. Choosing indoor plants that match that microclimate, or adjusting the microclimate to match the plants, is the most effective path to houseplant success.
High altitude and strong sunlight
Elevation increases ultraviolet light intensity and overall solar radiation. A south- or west-facing window in Colorado can deliver far more light than the same window at sea level. That benefits sun-loving succulents and cacti, but it also increases risk of leaf scorch for shade-adapted species. Light quantity and light quality both matter: plants will use the extra light if they can handle the spectrum and intensity.
Low humidity and indoor heating
Low absolute humidity is the single biggest indoor stressor in Colorado. Winter heating and summer arid air can drop indoor relative humidity to 15-25 percent, which causes leaf browning, increased water loss, and pest outbreaks (especially spider mites). Some tropical plants will tolerate this if you provide humidity boosts; others will not.
Temperature swings and drafts
Many Colorado homes experience significant diurnal temperature swings and localized drafts near doors, windows, and vents. Plants that dislike cold roots or cold drafts will show stress near leaky windows or in rooms that cool down overnight.
Assess your home before choosing plants
A short assessment of light, humidity, and temperature will save you time and dead plants. Follow these steps to build a reliable picture of your indoor conditions.
-
Spend a week observing light: note which windows get bright sun, dappled light, or only indirect light at different times of day.
-
Measure or estimate humidity: inexpensive hygrometers are useful; if you do not have one, place your hand near leaves for signs of dryness and watch for dusty, crispy leaf margins.
-
Record room temperatures: note daytime highs and nighttime lows, and locations of heating vents and drafty windows.
-
Create microclimates map: bathrooms and kitchens are often more humid; south-facing rooms are brighter and warmer; north-facing rooms are cooler and lower in light.
Choose plant types that match Colorado conditions
Match plant preferences to your assessed microclimates. Below are categories and specific, practical plant suggestions that succeed in Colorado homes when paired with the right spot and care.
-
Succulents and cacti: rattail cactus, echeveria, haworthia, aloe vera, crassula (jade). These tolerate strong light, low humidity, and build-in water storage.
-
Tough foliage plants: snake plant (Sansevieria/Dracaena trifasciata), ZZ plant (Zamioculcas zamiifolia), pothos (Epipremnum aureum), philodendron varieties. These are forgiving of low humidity and irregular watering.
-
Compact palms and drought-tolerant tropicals: ponytail palm (Beaucarnea recurvata), parlor palm (Chamaedorea elegans) where humidity is moderate.
-
Plants to avoid unless you can provide humidity: calathea, prayer plant (Maranta), maidenhair fern, most true ferns, and many aroids in dry rooms. These need consistent moisture and humidity and will struggle in dry Colorado air.
-
Flowering succulents and sun-loving bloomers: kalanchoe, kalanchoe tomentosa (panda plant), and some aeoniums. They thrive in bright windows with low humidity.
Why these choices work
Succulents and tough foliage plants store water, have thicker leaves or waxy cuticles, and tolerate low relative humidity. Pothos and snake plant are photosynthetically efficient at lower light and can recover from occasional neglect. Conversely, plants with thin delicate leaves evolved in understory rainforest conditions and need a more humid, stable environment.
Practical care: soil, pots, and watering in Colorado
Correct potting and watering are as important as plant selection. In dry, bright conditions, mistakes most often come from overwatering, poor drainage, or using a potting mix that retains too much moisture.
Soil mixes and drainage
Use well-draining mixes for most Colorado homes. For succulents and cacti use a gritty mix with pumice, coarse sand, and potting soil. For tropicals use a mix that retains some moisture but still drains: standard potting mix amended with perlite or orchid bark is a good compromise.
Always use pots with drainage holes. If you prefer decorative cachepots, lift the plant in its draining nursery pot inside the decorative container so excess water can escape.
Watering rhythm and technique
-
Water deeply and infrequently for succulents and drought-tolerant species. Let the soil dry to the first inch or two depending on pot size before the next thorough watering.
-
For tropicals that prefer moist but not wet soil, allow the top 1 inch to dry between waterings, then water until it drains.
-
Avoid frequent shallow watering. In dry homes, surface soil can look dry while the pot still holds water; probe with a finger or use a wooden skewer to test moisture depth.
-
Adjust watering seasonally: reduce water in winter if plants are cooler and receiving less light.
Root temperature matters
Elevated root temperatures from radiant heat or heat mats speed soil evaporation and increase water demand. Keep pots off direct heating vents and cool surfaces, and consider insulating pots on cold winter nights to avoid root chill near drafty windows.
Creating and using microclimates
You do not need to pick only drought-tolerant plants. You can create favorable microclimates for moisture-loving species with a few practical strategies.
-
Group plants together: plant transpiration raises local humidity and creates a small humid pocket.
-
Use pebble trays: set pots on gravel trays with water below the pot rim to increase humidity without waterlogging roots.
-
Place humidity-loving plants in bathrooms or kitchens with ambient humidity from showers and cooking.
-
Run a humidifier in plant-dense rooms during winter. A small humidifier set to 40-50 percent relative humidity will dramatically reduce leaf tip burn and pest problems.
Light management for Colorado winters and summers
Because Colorado light can be intense, acclimate plants slowly to stronger sun and manage seasonal changes.
-
Move a plant gradually closer to brighter windows over 1-2 weeks to avoid sunscald.
-
Provide filtered sun for plants that like bright but indirect light; sheer curtains or rotating plants away from mid-day sun reduce leaf scorch.
-
In winter, supplement short daylight with a full-spectrum grow light if you keep tropicals that need extended light hours.
Pest prevention and common problems
Dry indoor climates favor spider mites, scale, and mealybugs. Use inspection and early intervention.
-
Inspect new plants for pests before bringing them home: check undersides of leaves, new growth, and soil surface.
-
Increase humidity and wipe leaves regularly to reduce spider mite activity. A weekly leaf wipe with a damp cloth reduces dust that favors pests.
-
If pests appear, isolate the plant, treat mechanically (remove visible insects), and use soap sprays or horticultural oils as appropriate. Repeat treatments on a schedule until pests are gone.
Seasonal adjustments and winter care
Colorado winters require adjustments:
-
Move sensitive plants away from cold windows and exterior doors during night time.
-
Reduce watering frequency as plant growth slows and light levels drop.
-
Monitor for dry heat damage: keep plants away from forced-air vents and space heaters, and add humidity if indoor air drops below 30 percent.
-
Clean and rotate plants periodically so all sides receive light and you can inspect for pests or disease.
Buying and acclimating new plants
Choose healthy specimens from local nurseries that already grow at Colorado elevations when possible. Greenhouse-grown plants adapted to local light and humidity transition more easily than tropical greenhouse plants shipped from low-elevation, high-humidity regions.
When you bring a new plant home:
-
Quarantine it 1-2 weeks to watch for pests.
-
Acclimate it to local light gradually.
-
Repot only if the plant shows signs of being rootbound or if the nursery soil is very poor; otherwise wait a month or two.
Quick decision checklist: choose plants with confidence
-
Measure your light and humidity before you buy.
-
Match plant water and light needs to the best room in your home.
-
Favor succulents, cacti, snake plant, ZZ plant, pothos, and other drought-tolerant species if you have very dry, sunny rooms.
-
Create humid microclimates for fussy tropicals using humidifiers or groupings if you want high-humidity plants.
-
Use well-draining soil and pots with drainage holes to prevent root rot in a climate that also encourages evaporation.
Final practical takeaways
Selecting indoor plants for Colorado is about matching species traits to your actual indoor conditions and making small, practical adjustments where necessary. Prioritize hardy, water-storing plants in dry, bright spots; use humidifiers, grouping, and appropriate placement for moisture-loving species; and avoid overwatering and poor drainage. By assessing light, humidity, and temperature, and by following simple potting and watering rules, you can build a resilient indoor plant collection that thrives in Colorado’s unique environment.
