Arisaema triphyllum is most familiar to American gardeners. We're still working on photos for another native: Arisaema stewardsonii (sometimes considered a ssp. of triphyllum). The takedae x sikokianum hybrid is also listed here even though it is a cross made in Georgia between two Japanese species.
