A List of Sixty Choice Peonies of the More Expensive Varieties
Pink Varieties
Lady Alexandra Duff (Kelway).  9.1.  One of the largest and most beautiful of all peonies.  An immense, loosely built flower with great broad rounded petals so exquisitely arranged as to make a flower of most ravishing beauty.  In color it is a lovely French White.  This flower looks white but when closely scrutinized it shows the white tinted with the most delicate pink imaginable.  When not disbudded, the central flower is loosely double of a rather flattened, circular form, with the central petals touched with carmine.  It is a beautifully formed flower and sweet scented.  The plants are exceedingly free flowering and very showy.  The side flowers, which open after the central flower, come semi-double saucer shaped and show stamens.  Taken all in all this is positively one of the most beautiful of all peonies, and should we be asked to name the twelve most beautiful peonies Lady Alexandra Duff would be one of the twelve.

Kelway's Lovely Double Herbaceous Pæonies
Lady Alexandra Duff, lovely French white—that is to say, not a snow white, although when fully opened it is quite white; in the young stage tinted with a very fresh, delicate pale shade of what is commonly called "blush", or palest pink. The central flower (the first to open) is a full double flower of rather flattened circular form, and the central petals have a very small touch of carmine. It is a very nicely formed flower, and scented, and the plants are exceedingly free flowering and showy. The side flowers (which are freely produced, and which open after the central flower) come in semi-double saucer-shaped form, exposing the anthers. The back of the flower is flushed with pink near the stem. Tall and robust. One of the grandest varieties we ever raised. First-class certificate, R.B.S. Lady Alexandra Duff is included in the list of pink varieties amongst the commercial varieties recommended by the new Pæony and Iris Organization for the United States (9.1 rating.) 10/6 each. (See illustration.)
