Description of Mr. Richardson's Seedling Peonies.
The following is a list with descriptions of the Richardson seedling peonies, with synonyms where such exist and the awards they have received; these awards were all made by the Massachusetts Horticultural Society, so that for the sake of brevity the name of the Society is not further mentioned. The date of blooming this year is given, and also the height. The height was taken in August, and measures the distance from the ground to the calyx of the flower; with the flower, therefore, some inches would be added as a maximum height. The whole set of eighteen varieties was exhibited this year before the Society either on June 5, 11, or 21-22.
R. P. Whitfield. Named by me. Light pink, shaded to lighter in centre, rather flat bloomer, perfectly double, no stamens or stigmas visible, free bloomer. In bloom 20 June 1904, height to flower 40 inches. Named for Prof. R. P. Whitfield, palæontologist in the Amerucan Museum, New York.
