Blue Flag is the provincial flower of Quebec, Canada, symbolizing elegance and natural beauty.
Indigenous people and early settlers used the rhizomes for medicinal remedies, though the raw plant is toxic if ingested in quantity.
Each flower has three upright petals (standards) and three downward sepals (falls) with yellow “signal patches” to guide pollinators.
Forms clonal colonies over time, stabilizing wetland soils and providing habitat structure in marshy ecosystems.
