'Susan Louise'   Many areas of the United States are suitable for Gigantea Hybrids; we may hope that somebody in that country will try to use R. gigantea to breed huge rose bushes: something the size of a lilac bush, covered with flowers like 'Peace'. The example was set by Charles E. Adams of San Jose, California, who obtained 'Susan Louise' from the seed of 'Belle Portugaise' . Introduced by the Stocking Rose Nursery in 1929, she is semi-double, pink, scarcely known in Britain. Of course she is nothing like my vision of the lilac bush; I wonder if she might lead to it?

Charles E. Adams, Rev. George M. Schoener and Captain George C. Thomas of California represent Americans who have worked with [Rosa gigantea], but their results have been negligible. Undoubtedly, the best of their originations is Susan Louise, an everblooming seedling of Belle Portugaise, originated by Adams in 1919, and producing semidouble, deep pink blossoms.
