Cape honeysuckle is a vine rated fire resistant on limited evidence, with favorable planting guidance that still requires careful siting and upkeep.
The names can obscure the agreement. Valencia's low-flammability gardening guide lists Bignonia capensis among the recommended garden climbers. Fire Safe Marin lists the same plant as Tecomaria capensis, Cape Honeysuckle, and identifies its form as a vine. Tecomaria capensis is the accepted botanical name for Cape honeysuckle, so those differently named entries can be read together.
Marin makes its care conditions explicit. Its publication says fire-resistant landscaping requires attention to plant selection, placement and spacing, and that the listed plants need irrigation and frequent maintenance to resist ignition. The listing is therefore useful when selecting a vine, but the choice of where to grow it remains part of the decision.
Diablo Firesafe's compilation also includes Tecomaria capensis in its favorable fire-performance table and describes it as an evergreen vine. Its supporting references collect favorable plant judgments; the table does not present a series of burn experiments for this vine. The guide declines to rank the listed plants because the ranking terms in its references lack a shared definition. It also warns that inadequate irrigation, pruning or climate suitability can compromise fire performance.
For a gardener, the evidence supports considering Cape honeysuckle while preserving those conditions. Choose its position with spacing in mind, and account for the watering and pruning it will need as it grows.

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.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

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.

“Table 1: favorable fire performance rating in 3 or more references (refs 8,11,26,37,40,41,42,53)”
The Diablo Firesafe Council Guide to Plants lists Tecomaria capensis (Cape honeysuckle) as vine, evergreen, in Table 1: plants with a favorable fire performance rating in 3 or more references. The guide cites 8 of its 57 numbered references for this row (8,11,26,37,40,41,42,53). The guide states the ranking terms in its underlying references were mostly undefined and makes no attempt to rank within the list, and that fire performance is compromised without maintenance.
