Columbus follows Ohio's invasive plant guidance. The Ohio Invasive Plants Council identifies species to avoid including bush honeysuckle, autumn olive, Bradford pear, Japanese knotweed, and garlic mustard. Ohio banned sale of certain invasive plants effective 2025.
Columbus references the Ohio Invasive Plants Council (OIPC) list for invasive species guidance. Key invasive species in Central Ohio include Amur/bush honeysuckle (Lonicera maackii), autumn olive (Elaeagnus umbellata), Bradford/Callery pear (Pyrus calleryana), Japanese knotweed (Fallopia japonica), garlic mustard (Alliaria petiolata), and multiflora rose (Rosa multiflora). Ohio banned the sale of 38 invasive plant species effective January 2025 under Ohio Revised Code §927.70, including Callery pear and bush honeysuckle. Columbus Recreation and Parks actively removes invasive species from city parks and natural areas. The city's tree commission maintains an approved tree list for street trees that excludes invasive species. Columbus also participates in the Central Ohio Cooperative Invasive Species Management Area (CISMA).
Sale of banned species: state-level penalties per ORC §927.70. No residential planting ban, but new plantings strongly discouraged.
