Your local evidence lens
Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Fire-resistant — location does not change the cited classification.
- Fire-performance conditions
- 1 condition stated in cited fire-evidence rows.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 3 source placement records; source schemes remain separate.
- Evidence regions
- California; Cape Town, Western Cape, South Africa; Southern California; Valencia, Spain / western Mediterranean
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
2. Why this plant is relevant here
- State distribution
- Documented in CA.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- No introduced or established row is normalized; that does not prove native status.
- USDA hardiness
- No hardiness value is normalized.
3. Legal, ecological, and broader status
- Legal-list status
- Set a location for an exact legal-list result; source silence is not clearance.
- Seed-list status
- Set a location to compare the separate state noxious-weed seed layer.
- Reported invasive here
- No ecological invasive report is normalized; that does not prove noninvasiveness.
- Broader regional context
- Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
- Federal context
- Federal designations remain separate from state legal-list results.
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.

Fire-Retardant Plants for Brush Fire Prevention in Hillside Residential Areas
“CATEGORY 4 — LEAST FIRE RETARDANCE Plants with medium leaf moisture content capacity (60-70%)”
Hedera canariensis (Algerian Ivy) is one of 30 low-growing plants in the source's recommended Table 1. The category reflects leaf moisture capacity under normal garden conditions at the Arboretum.
-
“PLANTS FOR FIRE PROTECTION”
Hedera canariensis (Algerian ivy) appears in the source's conditioned examples for landscaping irrigated hillsides. Fuel volume is to be minimized, plants watered to their needs, and accumulated litter removed.

“Didn't burn”
Official-workbook means across 50 leaf trials: fresh ignition 6.849 s, fresh sustainability 29.846 s, dry ignition 0.485 s, dry sustainability 13.553 s, and combustibility 68.779 mg DW s-1. Published Table 1 observation for the 2021 fire: Didn't burn.
