1 Claim.

The present invention relates to a new and distinct variety of hybrid polyantha rose plant, originating'as a cross'between two known varieties Juanita and Mrs. R. M. Finchi' The new variety as thus produced, and hereinafter more particula rly described, constitutes a markedimprovement over its parents in a number of importantrespectsamong which may be noted that'while the flowers are similar to those of the pollen. parent, they arelarger and'darker in color; its growth isvery vigorous and resembles the seed parent in this characteristic; it is more productive than Mrs. R. M. Finchj since the latter is known to slow down in out flower production in the winter season; its flowers, furthermore, are larger than those of Juanita and they have many more petals than Juanita. Again, it differs from Mrs. R. M. Finch in that the stems are longer and more suitable for out flowers, the foliage is larger, and semi-glossy; more thorny with thorns not so long or hooked so much. Insofar as fragrance is concerned, it is similar to Mrs. R. M. Finch.

It will thus be seen that this new variety possesses many advantages over its parents, and also others considered either from the standpoint of individual or combined characteristics insofar as the particular class of roses to which it relates is concerned.

Asexual reproduction shows that these characteristics hold true through succeeding propagations, by cuttings, grafting, and budding.
