Exploring another trail some fifteen years ago the pollen of another native rose [R. macounii] was placed on R. rugosa flore plena. Part of the offspring, 5 to 6 feet tall, gave single and part semi-double flowers. These last have 12 to 17 petals, are 2 ½ to 3 ½ inches across, deep vivid pink, fragrant, of course, and with very abundant bloom from the middle of June into August. One has been named Nipsya. Two years ago a friend living in the Peace River country wrote me that Nipsya was the only rose which passed through the winter unscathed, the only one which bloomed the following summer. It is not unlike the Tetonkaha of Sr. Hansen, but apparently is much hardier and does not seem to sucker so badly. On this last point I am in doubt; a different soil might tell the other way.
