Soursop’s measured flame temperature does not establish whether it is fire resistant.
In a grill test using predried branches, researchers recorded a maximum flame temperature of 679.04°C, reported through Dryad and Global Ecology and Biogeography’s FLAMITS database. That number describes the highest flame temperature reached during the test. It does not, by itself, tell you how readily a living soursop tree will catch fire.
The distinction matters because flammability has several dimensions. How hot material burns is a different question from how easily it ignites. FLAMITS preserves the measured variable, experimental conditions and original study reference rather than applying a single fire-resistance threshold across different measurements and testing arrangements. There is therefore no basis for turning this temperature into a resistant or highly flammable rating. Its precision does not make it a safety grade.
Soursop, Annona muricata, is a tree in the Annonaceae family that reaches about 20 feet at maturity and needs moderate water. For someone considering it near a home, the fire finding remains specific to predried branches burned on a grill. It describes combustion under those conditions; it does not settle the planting decision.

How to read this page
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.
Native and introduced range evidence
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.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
Plant hardiness evidence
These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA
Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value
is not treated as a tolerance range. Different source boundaries stay separate: overlapping
statements are compared independently, while only ranges with no shared zone are called a conflict.
Source location: PlantCharacteristics record 71478, Temperature, Minimum (°F).
The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
