Species Details
Russian Comfrey is a newly established perennial of waysides, rough grassland and disturbed ground. This hybrid of Common (XXS. officinale) and Rough Comfrey (XXS. asperum) is frequent throughout Derbyshire, apart from the high moors of the Peak District. Of uncertain origin, it was introduced into Britain at the end of the 19th century as a fodder crop, but is little grown nowadays.
