Firewise Ratings
-
Firewise Suitability
- represents Landscape Zones 1, 2, 3, and 4. Zone 1 cannot be selected because Firewise does not recommend planting closer than 5 feet from the house. Zone 4 cannot be selected because recommendations greater than 100 feet from a structure are not made in this application.
-
Flammability
- refers to the ability of a plant to ignite and transfer heat and/or flames to surrounding plants or structures
-
Foliage Density
- provides valuable insight into the fire ignitability of the plant. Foliage density can also become contingent upon the overall mature size of the plant. Less dense foliage tends to have less actual fuel for ignition and less overall mass whereas very dense foliage can burn longer and hotter and increase the ignition of other plants and structures nearby. The combination of both of these—leaf characteristics and the amount of foliage—can greatly affect the fire performance of a particular plant.
-
Full Sun
- exposure where a plant receives full sun all day.
