Paeonia albiflora: Richardson Seedlings.
The following Peonies are seedlings raised by the late Mr. John Richardson of Dorchester, Mass., who was well known as a very skillful horticulturalist. The Peonies that he originated include some of the finest known varieties.
Norfolk (synonym Perfection. Named Perfection originally; but as another and older European variety is called Queen's Perfection and in catalogues is usually listed as Perfection, I changed the name in 1904 to Richardson's Perfection, thus retaining the original name but giving it a distinctive character.) Flower light blush pink, lighter in the centre, shaded to yellow at base of central petals. Perfectly double, very erect, free bloomer, very late. Choice. Silver Medal, 1869. $1.50.

Mr. Thurlow states that Mr. Richardson bequeathed his peonies to Mr. John C. Hovey, but that is a mistake. Mr. Hovey received what peonies he had as a gift during Mr. Richardson's life. Mr. Hovey when visiting me shortly before his death in 1894, on request dictated the names he had given and the descriptions of the Richardson peonies in his possession. As this is an important matter to peony growers his description is given at this point.
John C. Hovey's description of Richardson Peonies in his garden.
