Augustin d’Hour (Calot).  7.8.  This peony is mid-season and of bomb type.  It is an extremely large, showy flower.  Its primary petals are narrow and built up close and high.  It is a very deep, rich, brilliant solferino red, with slight silvery reflex.  It makes a splendid cut flower, and although it rates below 8, we feel that it has a place in any large collection.
