The following experiences of a single horticulturist (Ernest Walker, New Albany, Indiana), with one rose, illustrate this fact admirably. “I have had a number of sports of the Perle des Jardins rose,” he writes me, “in our greenhouses. The first one
was a double silvery pink with a short bud, and a very double, somewhat quartered flower. The stock of this I sold, as a new variety, for fifty dollars. The next sport was a white Perle. [The Perle is a golden-yellow rose.] I sold a plant of Perle to a local customer, who afterwards complained that it was not true to name, because the flower was white. She took it to be Cornelia Cook. I went to see the rose, and found a Perle rose in everything but color. I secured the plant, and was intending to introduce it, when, within a few months, I heard that Nanz & Neuner, of Louisville, Kentucky, had one, and that a London firm had another; and later I found that one had originated in Germany.
