TENT OFFICE ROSE PLANT` Roy L. Byrurn, Richmond, Ind., assigner to Joseph H. Hiii Company, Richmond, Ind., a corporation of Indiana 1 Claim. l

The present invention relatesl to a new and distinct variety of rose plant, the result of a dennite effort to improve primarily upon the color of the flowers of one of its parents while retainn ing the good qualities of said parent.

in carrying out this objective, 1 selected as the pollen parent a seedling (unpatented) which produced eXtra large blooms and good healthy growth. This seedling had the good qualities which were desirable for a rose suitable for greenhouse uses, but the red color of its blooms was not satisfactory. Therefore, 1 chose as the seed parent for this cross a seedling (also unpatented) which produced large, dark pink flowers, with the expectancy that the brilliancy of the pink would be added to the red and the cross thus result in a brilliant red color.

As will be seen from the accompanying illus tration, I succeeded in not only obtaining the improvement in color of the flowers, but a variety possessing the combination of characteristics of good, free growth, large size and brilliant deep red flowers, particularly suited for greenhouse uses, as well as others.

Asexual reproduction shows that the char acterstics hold true through succeeding `propagations.

In the drawings:

Fig. 1 shows a specimen of single stem and flower in the bud stage, as the calyX breaks;

Fig. 2 shows a specimen of flower as the petals first open;

Fig. 3 illustrates a full blown ower, its large size, large number, form and arrangement of its petals and petaloids;

Fig. 4 shows a section of a branch illustrating the characteristics of the thorns;

Fig. 5 shows the upper dark green surface of a specimen of the foliage; and

Fig. 6 shows the light green under surface of the foliage.
