Jack in the pulpit is rated fire resistant, with repeated low-flammability findings and a favorable Oregon planting profile.
North Carolina's 2005 guide and its 2025 successor both assign Arisaema triphyllum to their low category. NC State Extension's Plant Toolbox provides another low tag for the same species. Dovetail Partners also gives the plant a low assessment in its northeastern Minnesota work, using the University of Florida flammability key.
Oregon State University Extension supplies a different kind of support. Its Jack in the Pulpit profile belongs to the fire-resistant perennials suited to Willamette Valley conditions. That is a regional planting recommendation, compatible with the low assessments from the other publications.
This perennial has high water needs and belongs to the Araceae family. Its classification follows the repeated favorable findings, with the Oregon recommendation carrying its stated growing-region scope. A reader can use that combination to compare fire-conscious plant choices while keeping ordinary horticultural requirements, including water, alongside the fire rating.
