Native-plant and prairie landscaping is allowed in Lake County, but it must still comply with local rank-vegetation and detrimental-plant rules. Intentional native gardens are fine; they cannot become a cover for noxious weeds or exceed a municipal grass-height limit where one applies.
Indiana encourages native and pollinator plantings, and neither the state nor Lake County bans naturalized or prairie yards. The limits are the same weed rules that apply to any lot: IC 15-16-8 still requires you to keep out detrimental plants like Canada thistle and Johnson grass, and a city or town rank-vegetation ordinance can still cite an unmaintained lot that reads as neglect rather than a managed native bed. Homeowners planting natives should keep beds intentional, remove listed noxious species, and, inside incorporated areas, confirm the local code does not impose a turf-height cap.
A managed native garden is not a violation, but a lot that harbors detrimental plants or exceeds a municipal height limit can be cited and abated like any overgrown parcel.
