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
- No test or rating condition is normalized.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 3 source placement records; source schemes remain separate.
- Evidence regions
- Colorado / Rocky Mountain Front Range; Georgetown, Texas; Yavapai County, Arizona; southern Idaho / Intermountain
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
Typed publication scope: 4 scopes across 4 cited fire sources
2. Why this plant is relevant here
- State distribution
- Documented in DC, ID, MO.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- 1 sourced range or established record; set a location to match them. This is not an invasive warning.
- 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.

Ignition-Resistant Landscape Plants (Fact Sheet 6.305)
“ignitability score 8 of 10”
CSU 6.305 table lists Ceratostigma plumbaginoides (plumbago) with the preserved ignitability score.
-
Fire-Resistant and Fire-Prone Plants Common to Yavapai County (Bulletin 34)
“Fire-Resistant Plants”
Listed as Plumbago — Ceratostigma plumbaginoides. The bulletin says fire-resistant plants tend to resist ignition when irrigated and maintained, while fire-prone plants may ignite readily and burn intensely.
-
“low”
The table rates Leadwort Plumbago — Ceratostigma plumbaginoides low for flammability hazard, defined as the ease a plant can burn at high temperatures for a prolonged time.
