Compass Plant is a tall, mostly meadow sunflower with some very large leaves. The common name is derived from the plant's deeply incised leaves, which are oriented north-south. Native Americans chewed a gummy, fragrant-but-bitter resin from split or broken stems as a mouth-cleansing chewing gum. Rosinweed is a common name for many silphiums.
