United States - Patent No: PP 999   VIEW USPTO PATENT

The patent states "this variety resulted from a self pollinated seedling from one of my own unnamed seedlings developed in our greenhouses in Woburn, Mass. This variety is essentially a greenhouse rose but it can also be grown out of doors satisfactorily. It is a prolific producer of flowers and although not a robust grower is adequately strong to produce good bushes. It is not quite so hardy as the really strong growers."
