Banksia

Of seven assessed species, two are rated keep away, while five were assessed without the sources taking a side. Those five are unresolved, not evidence that they resist fire.

Silver banksia, the most-studied member of the genus, is rated keep away with a substantial body of assessment behind that finding. Coast banksia receives the same verdict on two listings. One assessment of coast banksia compared shoot time-to-flame, flame duration, flaming events, and flame temperature but did not turn those measurements into an overall class. Such measurements describe several parts of burning behavior; without an overall judgment, they do not by themselves establish resistance.

Banksias belong to the Proteaceae family and are grown as shrubs and trees. Heath-leaf banksia and hairpin banksia are also members of the genus, but their names alone carry no rating and cannot be placed on either side. The practical conclusion is therefore cautious but clear: the assessed genus contains no resistant example, its two definite verdicts both warn against close placement, and the remaining assessments offer no grounds for treating other banksias as fire-resistant substitutes.
