Sweetflag Interesting Notes

Acorus amercanus can be distinguished from the European A. calamus quite easily. Acorus calamus has a single distinct mid rib, while A. americanus has several indistinct ribs. A. calamus has naturalized over much of the US and in many areas is more common.

Acorus americanus was used extensivly by Native Americans and Early Settlers and has long been known for its medicinal value. The rhizomes of this plant were used as a substitute for ginger, cinnamon, and nutmeg and were also sought after by perfumeries.

Acorus americanus Growing and Maintenance Tips

Grow Sweetflag in moist to wet soils in full sun or bright shade. It is a vigorous spreader in wet soils and works well for retaining soil at the edge of a stream or pond. Tolerates periods of dry, but its appearance may suffer in long droughts.
