Genus: Arnica montana OR chamissonis
Family: Asteraceae (Daisy Family)
Growing Arnica: I grow the North American variety, since it is a native species here. Testing shows that the properties of both Arnica montana (European) and Arnica chamissonis (American) are very similar. The plants like acidic soil and will withstand our Canadian summers as long as it doesn’t get colder than -36 degrees C.
It likes moist soils and sun, although it does tolerate some shade.
It also boasts some beautiful daisy-like bright yellow flowers, so it makes a wonderful ornamental plant to plant alongside other flowering species. I see loads of bees around mine. The fact that it’s a medicinal herb and also a pollinator is a big plus in my books
What’s the difference between the Arnicas?
A.Montana grows in Europe, and is an old folk-remedy for pain and wounds.
A. chamoissonis is the North American variety.
In Norse mythology, the plant was sowed around wheat fields in midsummer because it was said to have protected the crops from the Norse demon Bilwis. It is an herb of Freya, and considered a sacred herb of midsummer.
