Full Breakdown
The Marion County Zoning Ordinance's general landscaping standards affirmatively permit growing native ferns, grasses, sedges, rushes, forbs, shrubs and trees in lieu of a turfgrass lawn, including in natural landscape areas designed to control and direct vegetation growth. The catch for front yards: natural landscaping can't be planted within two feet of the front lot line (four feet on other lot lines, unless screened by fencing or shrubs). A sign noting the area as a natural landscape area that generally isn't mowed must also be posted. Plants on the Indianapolis Prohibited Plant List don't count toward any landscaping requirement.
Violations & Fines
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.
