Canadian white violet is rated fire resistant by three regional plant programs, although one says more research is needed.
FireSmart BC includes it on a binary chart of approved fire-resistant plants, but also attaches a needs-more-research flag. That qualification tempers the approval without reversing it. Montana State University Extension lists the species among fire-resistant plants adapted to Montana, while Oregon State University Extension profiles it among fire-resistant plants that thrive under Willamette Valley growing conditions. Oregon gives its hardiness as USDA zones 3a through 8b.
The agreement spans British Columbia, Montana, and Oregon, each using a recommendation based on inclusion in a regional plant chart or curated list. Canadian white violet is a perennial in the violet family, native across the Southeastern, Northeastern, and North-Central United States. Taken together, the three recommendations support calling it fire resistant, with FireSmart BC’s research flag preserved as a reason not to treat that classification as the final word.
