Description:
If it were not for the lavender color of the flowers, 'Blue Girl' would surely have been dropped from the commercial market years ago. 'Blue Girl' is one of those roses which does poorly in many situations, yet, from those gardeners who are fortunate enough to succeed with her, she earns rave reviews.  Unfortunately, I have never been one of the lucky ones. 

Large, somewhat informal flowers of lavender move towards pink on the color scale.  Like all of the so-called 'blue roses', 'Blue Girl' is not blue.   The blue pigment in flowers, delphinidin, is not naturally present in roses; past introductions of 'blue roses' have been lavender or light magenta. 

To succeed with 'Blue Girl', care should be excellent.  Make sure that proper soil conditions are maintained, and that a spray for blackspot is administered on a regular basis.    Also, a final hint regarding 'Blue Girl':  gardeners who succeed best seem to live in less humid climates.
