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.
George B. Sowerby. Named by me. Guard petals delicate pink, in a flat row like a saucer, inner petals long, narrower, wrinkled, laciniated, white shaded yellow, very double, no stamens, but the stigmas are visible in centre when fully opened, very vigorous, free bloomer. Mr. Richardson aptly compared it to ice cream in a pink saucer. Very early, in bloom 4 June 1904, blooms have been supplied for decorations when no other Chinese peonies were to be found in the market, height to flower 39½ inches. Not one of the best of Mr. Richardson's seedlings, but desirable on account of its earliness and is a fine flower. Named for George B. Sowerby, an English conchologist.
