ROSE PLANT I Roy I]. Byrum, Richmond, Ind., assignor to Joseph 1H."Hill Company, Richmond, Ind., a corporation of Indiana 1 Application November 15, 1941-,Seria1 No. 419,350-

' I Claim. (c1. 4761) The present invention relates to anew and distinct variety of hybrid tea rose, originating from a cross between the known varieties Joanna Hill and R. M. S. Queen Mary (Plant Patent No. 249) to obtain improvements over each.

' As a result, I have produced a rose similar in growth, shape .of bud and bloom to .Captain .Glisson (Plant Patent No. 155), but having more similarity in texture of foliage to R. M. S. Queen Mary, above referred to.

Its primary distinguishing. features 'reside in the color of the flowers, darker than that of either of its parents, its great productiveness, the blooms coming on long stems from a out without resorting to pinching, and the resistance to mildew and blackspot. The great productiveness above referred to was based upon cutting records for a period of years in comparison with 'standard varieties, and the resistance to 'mildew and blackspot characteristic was. determined by growing the present variety next to a variety :on which blackspot has been present throughout the growing season. On the other side of this new variety is one which has had mildew at various times during the season, However, the present variety entire time under identical growing and disease preventive conditions. These distinguishing characteristics have been found to hold true through succeeding propagations by the usual methods tried of cuttings, graftings and buddings.

The color terminology herein employed is in accord with Ridgways Color Standards where indicated by plate numbers, otherwise with general dictionary meaning.
