Wyoming, MI Invasive Plant Rules: Prohibited Species (2026)

Section 82-63(3) of the Wyoming Code of Ordinances flatly bars planting, propagating or cultivating noxious weeds on any parcel in the city, and separately prohibits letting noxious weeds remain on property a person owns or controls, a standing duty rather than a one-time planting rule. Section 82-62(e) defines 'noxious weeds' by an enumerated list plus a catch-all for any plant the Michigan Department of Agriculture and Rural Development designates noxious. The named species run from common lawn and field invaders like Canada thistle, bull thistle, field bindweed, quack grass and yellow nutsedge to toxic plants such as poison ivy, poison oak and poison sumac, plus jimson weed, wild mustard, wild oat and dozens more listed by common and scientific name.

The prohibition sits inside Chapter 82 Article III, Lawns, Gardens and Water Efficient Landscaping, rewritten by Ordinance No. 10-22 on May 16, 2022, and it applies citywide in Wyoming, Kent County, Michigan, not just within public rights-of-way. Property holding a city-issued water efficient landscaping permit under Section 82-64(3) is exempted from the separate ten-inch turf-height rule in subsection (4), but that exemption does not reach the noxious-weed ban in subsection (3), which the code text keeps in force for every parcel regardless of any landscaping permit.
