Mentha canadensis

''Mentha canadensis'' (syn. ''M. arvensis'' var. ''canadensis'') is a species of mint commonly known as American wild mint, native to North America (from Northwest Territories to central Mexico), eastern Asia (Siberia to Java) and the Northern Territory of Australia.〔(Kew World Checklist of Selected Plant Families )〕 The flowers are bluish or a slight violet tint. The plant is upright about to tall. Leaves grow opposite from each other, and flower bunches appear at the upper leaf axil. The mint grows in wet areas but not directly in water, so it will be found near sloughs, lake and river edges. Flowers bloom from July to August.
The related species ''Mentha canadensis'' is also included in ''Mentha arvensis'' by some authors as two varieties, ''M. arvensis'' var. ''glabrata'' Fernald (in reference to North American plants) and ''M. arvensis'' var. ''piperascens'' Malinv. ex L. H. Bailey (in reference to eastern Asian plants).〔Germplasm Resources Information Network: (''Mentha canadensis'' )〕
