E. F. Allen, Awards To Rose Seedlings In Great Britain In 1981. 
'Clarissa'  HARprocrustes ('Southampton' x 'Darling Flame') a tall miniature, to 75 cm, with clusters of small, double flowers of an orange apricot blend. Almost without scent and with a tendency to harbour powdery mildew in September, yet I have usually found this seedling to be attractive.  Trial Ground Certificate.
