1 Claim. 1

The present invention relates to a new and distinct variety of rose plant, resulting from a definite effort to combine certain desirable characteristics of the parents employed to thereby produce a greatly improved rose stock.

In carrying out my objective, I selected an unnamed seedling for the seed parent because'of its extra large bloom and good growth habit, but its bloom color was not satisfactory. For the pollen parent, on the other hand, I selected an unnamed seedling because of its extra good bloom color and good foliage, but having only a fair growth habit.

By crossing these two experimental seedlings, I was able to produce a rose plant having the desirable bloom color of the pollen parent and the large size of bloom and growth habit of the seed parent.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.

In the drawing:

Figure 1 is a detail view of the bud of this new variety, illustrating its long stem and single bloom characteristic;

Figure 2 is a similar view of a specimen as the first petal opens;

Figure 3 is a top view of the bloom at full blown stage, showing the irregular arrangement and color of the very double petals; I

Figure 4 is a view of the under side of specimen of the foliage, a compound of three leaf group;

Figure 5 is a view of the upper side of a compound of the seven leaf group produced by the plant; and

Figure 6 is a specimen of the plant canes, showing the characteristics of the thorns.

The following is a detailed description of the new variety, color terminology being in accordance with Ridgways C'olor Standard, except where otherwise indicated to have ordinary dictionary significance:
