Rare Single Japanese Peonies
The so-called Japanese Peonies are those which have one or two rows of petals and centers of stamens much thickened. These are almost devoid of pollen and oftentimes make a thick cushion of golden yellow. The effect is very beautiful and distinct and they continue to bloom throughout the Peony season. Although strong growers they propagate slowly and the stocks are usually limited.
Purity (Bunting), pure white petals surrounding a mass of pale yellow filamentary stamens. A dainty flower. $5.00 each.

"The American Peony Show at St. Paul" by Edward Auten, Jr.
...The Thurlows had a large and striking exhibit of singles and Japs, wonderfully fresh to have come so far. The outstanding kinds were Sophia Houston; Purity (Bunting); Eglantine, which was shown in most exquisite color; Black Prince, a fine deep red, with a good mass of yellow stamens, and green carpels which do not spoil the effect as the red ones do in so many varieties.
