Pineapple has been measured for flammability, but the result does not establish that it is fire resistant.
Dryad and Global Ecology and Biogeography’s FLAMITS database reports a maximum flame temperature of 266.1°C for pineapple branch material dried before testing on a grill. Sampling took place from October to November 2022.
That temperature describes the hottest the flame became during the test. It does not describe how easily the material caught fire. The distinction matters because flammability has several dimensions, and FLAMITS preserves the measured variable, experimental context and primary study behind each value. The database does not impose a single threshold across unlike measurements, devices and plant parts. There is therefore no basis for reading this temperature as a passing or failing fire-resistance score, or for calling it high or low without an applicable scale.
Pineapple, Ananas comosus, is a perennial in the Bromeliaceae family that reaches about three feet at maturity and needs moderate water. For a homeowner considering it, the fire finding remains specific: dried branch material produced a measured flame temperature under grill testing. Pineapple has not received an overall verdict for or against fire resistance from that measurement.

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 30882, 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.
