Mouse-ear Hawkweed (Hieracium Pilosclla, L.) 



Widely dispersed on hilly ground this pretty Hawkweed was quite 

 an old-established species in the British Islands in the Glacial period. 

 It is found in Interglacial beds at West Wittering, Sussex, and it is 

 the only species of this large and polymorphic genus found in Britain 

 so early. At the present day it occurs in the North Temperate Zone 

 in Europe, N. Africa, North and West Asia. Mouse-ear Hawkweed 

 occurs in all parts of Great Britain except the Shetlands, ranging else- 

 where as far north as the Orkneys, and ascends to 2400 ft. in 

 Yorkshire. It is native in Ireland and the Channel Islands. 



This common Hawkweed is a xerophilous plant, growing usually 

 on dry ground, at a more or less high altitude on hills and mountains, 

 on sandy soil. It is fond of growing on rocky ledges, or where rocks 

 crop out at the surface and are exposed by denudation. Similarly, 

 walls are another suitable and frequent habitat. This Hawkweed is 

 associated with Bird's Foot, Vernal Grass, and other rupestral types.
