This map is based on our research. We have checked its accuracy to Level 4 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
This species is somewhat widely planted across North America, and has been reported in the wild from a single location along a stream, in the coastal plain, in the DC area, in Fairfax County, Virginia. FSUS treats it as a waif, meaning it probably did not persist. Because it is a relatively nondescript plant that resembles many other species, it may be underreported and may occur on, or at least have temporarily established at other sites.
↑Uses
This species is occasionally planted in landscaping. We recommend against planting it, as it may have some invasive potential, as it has temporarily established in the wild on at least one site. The closely-related calamus (Acorus calamus) is invasive in North America.
