Notes: Like most hawkweed species, Hieracium pilosella shows tremendous variation and is a complex of several dozens subspecies and hundreds of varieties and forms. Mouse-ear Hawkweed favours dry, sunny areas. It grows well on sandy and similarly less fertile ground types. It produces stolons which generate a new rosette at their extremity, each rosette has the possibility of developing into a new clone forming dense mats in open space. The plants medicinal properties (anti-inflamatory) were recognized back in medieval times, though nowadays it is considered a weed in some parts of the world.
