Eastwood's manzanita has been tested for ignition, but its fire resistance remains unresolved.

The FLAMITS database, published through Dryad and Global Ecology and Biogeography, reports a temperature at flaming of 403.18°C for live leaves that had not been dried before testing with a flat flame burner. That number describes the temperature recorded when flaming occurred under those experimental conditions. It is not a fire-resistance grade for the whole shrub.

FLAMITS keeps each observation tied to its experimental context while covering five dimensions of flammability. It does not impose a single threshold that turns unlike measurements into resistant or flammable verdicts. The measured temperature should not be treated as a universal boundary below which Eastwood's manzanita cannot burn.

Eastwood's manzanita, Arctostaphylos glandulosa, is a shrub in the Ericaceae family, native to the southwestern and northwestern United States. For someone considering it near a home, the leaf experiment offers information about ignition under a particular test. It leaves the practical question of fire resistance unresolved.

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 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.
