member.  Its habit is more robust than that of either parent,  
 and the colour of the flowers, as might be  expected, exactly  
 intermediate,  being  of  a  rich  purple.  The  plant  does  not  
 produce  seeds,  but  it  appears  to  grow freely,  and  is  easily  
 increased by parting  the roots.  It is  equally hardy with L.  
 fulgens,  and,  like the  other North American  species  of the  
 genus,  it delights in  a soil composed of two parts of peat,  or  
 vegetable earth,  one  of loam, and another of river sand. 
 The  generic name  is  already  explained at  fol.  86.
