R. Marion Hatton.  The World's New Roses. 
A few days after the Jap raid on Hawaii (December 7, 1941), Fred Howard wired me that he was applying for registration of their new Roses under the names Anzac, Douglas MacArthur and Pearl Harbor. Registration was effected in due course, and the varieties were offered in this spring's catalogues. None of these is going to create excitement in the shows, but the gardener is going to like their respective plants.
Radiance sticks out all over Pearl Harbor, with flowers of just about the same colour, both inside and out, but the petals are much longer than those of its famous ancestor, making one of the largest buds we have, and each bud is alone on unusually long, smooth stems. The practically thornless canes are easy to work with. Unfortunately, Radiance's sweet fragrance is missing.
