However, supposing we are as near black as to blue, the following list will serve to indicate the best of the blackest roses: Baron Chauraud, scarlet with blackish centre; Black Prince, well named, crimson shading to purplish black; Cardinal Patrizzi, crimson shading to black; Louis Van Houtte, red shading to blackish crimson and purple—this ought, perhaps, to be in the list of blues— Monsieur Boncenne, blackish purple; Souvenir de William Wood, the blackest of the black, a fine rose, with rich shadings of red and purple; Xavier Olibo, velvety black shaded with fiery red.

Rose: Black Prince.-This is one of the many roses raised by Mr. William Paul, of Waltham Cross, Herts: both foliage and flower are very good. This rose received a first-class certificate at the Royal Horticultural Society, and is a general favourite, as it blooms freely out of doors and also forces well.
