Defensible space should extend at least 100 feet in all directions from the home and attached structures; on terrain steeper than 20 percent, as far as 200 feet. A fire-resistant home has at least 30 feet of surrounding space clear of dead vegetation and flammable debris and at least 5 feet of noncombustible mulch such as river rock or pea gravel. Within 5–30 feet, trees should have a minimum of 18 feet between treetops. Do not plant vines or ornamental grasses within the defensible space, particularly near the home. Switchgrass (Panicum virgatum) is extremely flammable. For areas nearest the house, select plants with the lowest flammability rating. Tables 3 to 5 rate North Carolina native plants. Table 5 high-flammability natives include American holly, eastern redcedar, longleaf pine, loblolly pine, eastern white pine, mountain laurel, Catawba rhododendron, and switchgrass. Not all native plants are suitable in the coastal plain, piedmont, and mountains.","asOf":"2026-08-25T00:00:00.000Z","object":{"kind":"guide","id":"what-the-nc-toolbox-rates-that-surprises-people","title":"What the NC Toolbox rates that surprises people","url":"/guides/what-the-nc-toolbox-rates-that-surprises-people/"},"source":{"title":"Fire-Resistant Landscaping in North Carolina (AG-874)","url":"https://content.ces.ncsu.edu/fire-resistant-landscaping-in-north-carolina","publisher":"NC State Extension","sourceType":"official","accessedOn":"2026-08-25T00:00:00.000Z","documentDate":"2025-03-26T00:00:00.000Z"}}],"local":[]},"placeFocusedGuides":[],"findings":[],"plants":{"grain":"state","total":687,"nativeDocumented":81,"invasiveOrNoxiousFlagged":170,"fireResistant":369,"keepAway":90,"conflicts":18,"page":"/grow/north-carolina/"},"fireEvidencePublicationScope":{"answerGrain":"typed-state-source","sourceCount":1}}
