Red Winter Cos Lettuce. 



very deeply coloured with red-brown. It is only in the centre of 

 the plant, near the head, that any green colour is visible. This 

 variety generally heads very well without being tied up. It is 

 hardy, productive, and remarkably slow in running to seed. It 

 is also so constant in character that 

 it is hardly ever found to vary or 

 degenerate.
