Will tolerates almost full shade but it does best with part afternoon shade in the Treasure Valley. With moist soils, it will grow and spread freely, it also self-seeds becoming invasive in optimum growing conditions. It is unique with its pretty chartreuse flowers and in one of the photos you can see how pretty the flowers are when grown amongst a red rose. It is used as a medicinal herb.
