Yellowstone County does not require or prohibit native-plant landscaping. Residents may plant Montana natives and drought-tolerant xeriscape freely, provided any designated noxious weeds are still controlled as state law requires.
There is no county ordinance mandating a particular landscape type or blocking native and xeriscape plantings on private land in unincorporated Yellowstone County. Native grasses, wildflowers, and drought-tolerant species are permitted and well suited to the semi-arid Billings climate. The one firm legal limit is the mandatory noxious-weed duty: even a naturalized or 'wildflower' yard may not harbor plants on the Montana statewide noxious weed list. Inside the City of Billings, an unmanaged native planting that exceeds the 12-inch nuisance-weed threshold or contains noxious weeds could still draw a nuisance notice, so keep native areas tended and weed-free.
No penalty for choosing native plants. Enforcement only arises if the planting contains designated noxious weeds (state weed-control duty) or, inside Billings, becomes an untended nuisance over 12 inches.
