EPA Level III Ecoregion
Northwestern Glaciated Plains
495 native plants for the Northwestern Glaciated Plains ecoregion (Great Falls area).
The Northwestern Glaciated Plains cover northern Montana and northwestern North Dakota, including Great Falls, Havre, Minot, and Williston. Glaciers left rolling till and shallow potholes across mixed-grass prairie, and the climate is semi-arid with brutal winters and a short intense growing season. Natives like Rocky Mountain blazing star, Missouri gooseberry, and largebract Indian breadroot are prairie plants that come through that cold and make use of a narrow window of moisture.
Conditions: Glacial till and clay with shallow potholes, 12–18 inches of precipitation, extreme cold winters, short warm summers, persistent wind.
Cities and areas: Great Falls, Havre, Minot, Williston, Lewistown, Glasgow.

Fall care in the Northwestern Glaciated 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 when it earns its keep. Lavender blue flowers open late and feed pollinators before winter on the northern plains. Leave most of the plant standing.
- Little bluestem
Fall is the best season for little bluestem in the landscape. The foliage turns a rich rust-orange and the seed heads catch low light, and this color and structure is worth leaving up rather than cutting.
- Switchgrass
Fall is switchgrass at its best. The foliage turns gold and the seed heads catch low light. It also feeds birds, so many gardeners leave it standing.
- Wild bergamot
In fall the plant ripens seed and heads into dormancy. On the Hi-Line you can leave seed heads for birds or tidy the bed, either works.
