Use only plants with a low flammability rating near your home. In general, beyond 30 feet, you can start adding those that are classified as moderate if they are kept pruned. Highly flammable plants can also be used in this area, but only if they are not close to other plants and are well maintained. Beyond 100 feet, plants may be spaced in a more natural setting.

This list is meant to be a very general guideline for selecting plants based only on their presumed flammability ratings, and was compiled from several sources. The ratings of a few plants differed, depending on the source. Please remember, there are no “fire-proof” plants.
