A List of Fifty of the Best Inexpensive Varieties
Pink Varieties
Grandiflora (Richardson).  8.8.  Pink.  A very large flower of true rose type.  In form this is one of the most beautiful of all peonies.  Seen from a distance, it immediately catches the eye because of the wonderful perfection of the flower.  A rather flat bloom, very large with a very graceful and beautiful arrangement of the petals.  A soft shell pink, shading to white with faint shadings of rose.  
Grandiflora is a very late variety.  We consider it the best of all the very late pinks.  When one thinks that the peony season is finished he can still go out and cut fine blooms of this most beautiful variety.

Descriptive List of Chinese Peonies
Grandiflora. (Richardson, 1883.) 8.8.
Double type; very large; very late. Bright pink, shaded old-rose and white, with some yellow at base of petals; fragrant. Tall; floriferous; weak stems. Heavy foliage.
Immense, flat flowers of attractive color. Useful for extending the season because it is one of the last varieties to bloom.
"I should call it bright rose-pink. It does not give the impression of having old-rose or white in it, or any yellow to speak of."—Saunders.
"I agree with Dr. Saunders. It has considerable blue. The petals have a tendency to roll up, giving a pointed effect like a pond-lily. It is a very distinct and beautiful flower."—Thurlow.

NB: Two of Richardson's peonies were called 'Grandiflora'; this likely accounts for the differing descriptions.

Mrs. Pleas' Estimate of Her Own Peonies
by Sarah A. Pleas.
Elwood Pleas is as yet the prettiest solidly double, light shell pink, similar but larger and more floriferous than Richardson's Grandiflora, a close rival.
