A genus split is not a placement verdict. Set a ZIP to read the local documented split.
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
These are exact U.S. botanical-area records from the cited range source. Native and introduced describe biogeographic relationship, not fire performance or planting approval. Doubtful and extinct rows stay visible but do not count as current presence.

Flammability of native understory species in pine flatwood and hardwood hammock ecosystems
“Most flammable species studied”
Aboveground plant structure, foliage, litter, stems, moisture, volatile solids, and energy were compared across the study taxa.
Fire in the Wildland-Urban Interface: Selecting and Maintaining Firewise Plants for Landscaping
“usually highly flammable”
The source describes it as an evergreen shrub that accumulates dead branches near the ground and says both living and dead leaves are flammable.
North Carolina Extension Gardener Plant Toolbox — plant profiles and flammability ratings
“high flammability”
NC Toolbox facet capture lists "Serenoa repens" under the high flammability tag.
Landscaping to Reduce Wildfire Risk: South Florida Edition
“Palmetto is a highly combustible shrub that must be managed.”
The guide says palmetto burns even while green, exudes a flammable oily resin, and should have dead fronds removed. Its earlier caption identifies the pictured vegetation as saw palmetto.
