Bulletin

Abstract

In Bulletin No. 22 we gave in detail our work in crossing the Russian Rosa rugosa with pollen of a number of the best garden roses. The crossing was done in the summer of 1892, and the seed planted the following spring. In the fall of 1893 the plants were potted and wintered in the cellar. The following spring they were planted out in nnrsery rows where they now stand. In the fall of 1894 the tops were cut back to mere stubs which were covered with earth. During the past season (1895,) they have made a rampant growth which has been unfavorable for the blossoming of such young plants. As a rule, the hybrids showing most variation from the Rosa rugosa mother have not bloomed, while those following more nearly the mother in leaf and habit have given more bloom. At this time we will only report two of the wide variations which have blossomed quite freely at this tender age.
