BOTANICAL IDENTITY
The right name is the first step.
Also known as: Acorus tatarinowii, Acorus verus
The inventory uses Acorus tatarinowii Schott; Kew treats that name as a synonym of Acorus verus (L.) Raf. This botanical relationship does not make every commercial “sweet flag” preparation interchangeable. A photograph alone cannot establish identification for consumption.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
