Viola hirta is a species of the plant genus Viola. It is also called the hairy violet. As with the sweet violet, no fossil seeds of this species have been found. It is confined to the cold temperate zone, in Europe, north and west Asia, extending as far as northwest India. It is absent in Wales from Brecon and Radnor, Pembroke, Cardigan, Merioneth, and from Mid Lancs, and the Isle of Man, but elsewhere it is universal. In Scotland it does not occur in Roxburgh, Berwick, Haddington, Edinburgh, Fife, Forfar, Kincardine. From Forfar it ranges to the south of England, and is found at a height of 1000 ft. in Yorks. It occurs also in Ireland.
