The trillium is a flower native to North America, with three large white petals atop a whorl of three sepals (hence its name). Its form is similar to the charge known as the tierce-feuille, in the arms of von Buderich, c.1370 [Gelre 93]. However, as a New World flower, the trillium’s use is considered a step from period practice.
The trillium is shown affronty by default, with a petal to base; it has no proper tincture in Society armory.
