Descriptive List of Chinese Peonies
Madame Forel. (Crousse, 1887.) 7.7.
Double type; very large; late midseason. Even, clear pinkish lavender throughout; all petals large and smooth; center compact; slightly fragrant. Medium height; moderate bloomer; weak stems. Average foliage.
Generally unsatisfactory. The buds frequently blast, and when they do open the stems are too weak to support the enormous flowers. The color is rather flat and opaque, much nearer lavender than pink. Included in this list by vote of Directors.
