How Indianapolis Handles Invasive Plant Rules: A Practical Guide
Indianapolis maintains 131 local ordinances across all categories, and 3 of those deal specifically with invasive plant rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Indianapolis falls on the strict-to-permissive spectrum compared to other cities.
Tree-of-Heaven Removal
Indianapolis declares the ailanthus, or tree of heaven, a public nuisance and orders lot owners to remove it within 30 days of notice.
Key details: Governing section: Code Sec. 391-112. Removal deadline: 30 days after notice. City-owned trees: DPW must destroy. Nonpayment remedy: City removes, bills owner.
Missing the 30-day removal deadline after notice exposes the owner to a Sec. 103-3 penalty and a city-billed removal charge for entering the property and cutting the tree down.
Front Yard Gardens
Indianapolis zoning lets property owners replace turfgrass with native plants in the front yard, but natural landscaping must sit at least two feet back from the front lot line.
Key details: Front lot line setback: 2 feet minimum. Side/rear setback: 4 feet, unless screened. Sign requirement: Must post 'natural landscape area' sign. Banned species: Indianapolis Prohibited Plant List excluded.
Natural landscaping placed inside the required 2-foot front setback or missing the required identification sign can be cited as a landscape-plan violation, with civil penalties up to $2,500.
If you are coming from a city with tighter rules, you will find Indianapolis gives residents more flexibility on front yard gardens.
Prohibited Species
Indianapolis bars planting box elder, silver maple, tree-of-heaven, mulberry, Siberian elm and eleven other listed species along public streets, alleys and rights-of-way unless the department approves a written exception.
Key details: Banned species count: 15 listed tree species. Examples: Box elder, silver maple, Siberian elm. Exception: Department may approve by written request. Scope: Consolidated City only, not excluded cities.
Planting a listed species without written department approval violates Sec. 701-5; the department can require removal, and the department or director may prosecute violations with the city prosecutor's office under Sec. 701-2.
The Bottom Line
Indianapolis's invasive plant rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Indianapolis is broadly strict or permissive.
