Waste places, under walls and hedges, frequent. Fl. July, Aug. 

 1. The root, boiled with alum, is said to dye yarn of a yellow co- 

 lour; from the fibres of the stalk a kind of hemp is manufactured, as 

 with the Urtica cannabina of N. America, (Whitlow's Nettle), and 

 I remember having seen several years ago a piece of very good linen 

 made from it, under the direction of a lady at Ballitore. In Scotland 

 the young tops of Nettles are boiled and eaten by the peasantry ; and 

 they were also much used by many of the poor in the north of Ireland 

 during the late years of scarcity, owing to the failure of the potato 

 crop?.

 are often called.
