[Wikipedia] Description, Range: Mentha canadensis is a species of mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java). In North America, it is commonly known as Canada mint,[3] American wild mint,[4] and in Asia as Chinese mint, Sakhalin mint,[5] Japanese mint,[6] and East Asian wild mint.[7] The flowers are bluish or have a slight violet tint. The plant is upright, growing to about 4?18 in (10?46 cm) tall. Leaves grow opposite from each other, and flower bunches appear in the upper leaf axils. The mint grows in wet areas but not directly in water, so it will be found near sloughs, and lake and river edges. Plants bloom from July to August in their native habitats.[8] The plants found in eastern Asia have been called Mentha sachalinensis, among other synonyms.

The flowers are borne in spikes at the tips of the shoots. The flowers may be bluish, pink or white. They are arranged in a spiral around the inflorescence. Each flower has five sepals, four petals, four stamens and a superior ovary. The fruits are dry and split open when ripe releasing the two seeds.[4] (link added by Mary Ann Machi)
