[From The Tree Peonies, by John C. Wister & Harold E. Wolfe, 1955, p. 18:] In the 1920's, the Yokohama Nursery was still sending to this country a beautiful book of color illustrations of fifty named varieties and offering these varieties for sale. Various persons importing these received good plants, the flowers of which hardly ever corresponded to the illustrations. On one occasion, one of the present authors wrote to the nursery asking if it might be possible, by paying extra, to get an authentic set corresponding to the illustrations, this set to be used to establish the correct names of the plants in this country. He received an indignant reply from an American living in Japan who was at that time
the president or general manager of the company. The letter stated that no business was desired from and that no plants would be sent to anyone who didn't like the company's method of doing business, or their method of labeling!
