EPA Level III Ecoregion
Northwestern Great Plains
724 native plants for the Northwestern Great Plains ecoregion (Billings area).
The Northwestern Great Plains roll across eastern Montana and Wyoming into the western Dakotas, taking in Billings, Rapid City, Casper, and Gillette. This is semi-arid shortgrass and sagebrush country, with hard winters, wide temperature swings, and long dry spells broken by sudden storms. Natives like blue giant-hyssop, golden prairie-clover, and plains beebalm are deep-rooted enough to ride out a dry summer with no irrigation at all.
Conditions: Clay and sandy soils over shale, 12–18 inches of precipitation, cold windy winters, hot dry summers punctuated by sudden storms.
Cities and areas: Billings, Rapid City, Casper, Gillette, Miles City, Dickinson.

Fall care in the Northwestern Great Plains
What to do right now for plants commonly grown here. Each links to the full regional care guide for that species, with sources.
- Smooth aster
Fall is the payoff. Lavender blue flowers open late and feed pollinators before winter across the mixed grass prairie. Leave most of the plant standing.
- Little bluestem
Fall is when little bluestem shines, turning a deep rust-orange with coppery seed heads that catch the low prairie light. Leave it standing rather than cutting it back.
- Switchgrass
Fall brings the gold foliage and the ripe seed heads that feed birds. Most gardeners leave the clump standing to carry color and wildlife value into the cold season.
- Wild bergamot
In fall the plant sets seed and goes dormant. Around Billings you can leave seed heads for birds or tidy the bed for a clean fall look.
- Swamp milkweed
In fall the seed pods split and release silky-tufted seeds, and the plant starts going dormant. You get to choose how tidy to leave it, and both choices help wildlife or the next season.
Build a plan for the Northwestern Great Plains
Pollinator Patch turns plants like these into a front-yard plan tuned for the soil, climate, and HOA expectations of the Billings area.
