ROSE PLANT of Indiana Application September 19, 1947, Serial No. 774,915

1 Claim. 1

The present invention relates to a new and distinct variety of rose plant of the polyantha class, resulting from the crossing of the Juanita and Mrs. R. M. Finch varieties.

fhe distinctive characteristics of this new rose may best be understood by comparing it with the well-known polyantha variety Betty Prior (Pl. Pat. #340) which it more nearly approaches than any other varieties of this group. Dominantly, the present rose variety, in this comparison, grows much heavier canes, differs as to its thorns, and the flower is slightly larger and of entirely different color, all as hereinafter more specifically disclosed.

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

In the drawing:

Figure 1 is a view of the bud of this new variety, before the calyx breaks, showing its small size and the foliaceous appendages;

Figure 2 is a view of the loud as the petals begin to open;

Figure 3 is a top view of a specimen of the full blown flower, showing its distinctive color and petal arrangement;

Figure 4 shows the reverse side of the bloom and the difference in color of the under reverse as compared with the upper surface;

Figure 5 is a top view of the specimen of the foliage, showing the compound of seven leaflets;

Figure 6 is a reverse view of a specimen of the foliage, showing the compound of five leaflets; and

Figure 7 is a view of a specimen of a main stem, showing the cluster arrangement of blooms and the particular characteristics of the distinct thorns.

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

This description of a newly opened flower was made from a rose grown outdoors in th month of June, at Richmond, Indiana:

Colon-Outside petal-outside surface: Spinel Pink, Plate XXVI; inside surface: Thulite Pink, lightly pencilled with Spinel Pink, Plate XXVI. Inside petal-outside surface: Spinel Pink, Plate XXVI; inside surface: Thulite Pink, pencilled with Spinel Pink.

This description was made from a rose that was open for three days outdoors in the month of June, at Richmond, Indiana:

Colon-Outside petaloutside surface: Thulite Pink, shading to white at base of petals; inside surface: Cameo Pink, pencilled with Thulite Pink, both Plate XXVI. Inside petal-outside surface: Thulite Pink, shading to white at base of petals; insid surface: Cameo Pink, pencilled with Thulite Pink,

General color affect-Newly opened flower- Spinel Pink. Three days open-Thulite Pink.

Behavior.-Persist.

Flower Zongevity.n bush in garden-five or more days in June. Cut roses grown outdoors kept at living-room temperatures-four to'five 'days in June:

It will now be apparent that this new variety resembles its seed parent in color and in the fact that'its bloomis single. However, it is not as free avbloomer as Juanita and its grows more in clusters than the latter. The new rose resemblesits pollent parent as regards the cluster growth, but said parent has more petals and is a lighter pink. The petals of Mrs. R. M. Finch are the same in color on top and bottom, while those of this new varietyare dark on the bottom and light on top. Actually, the purpose of making this. cross was to improve upon the Mrs.

R. MJ'Finch variety in respect to the flower and.

this objective was accomplished.

I claim: A'new and distinct variety of rose plant of the polyantha class, characterized as to novelty by its heavy canes, the form and'color of its thorns, and-"by" the size'and color of its'blossoms, sub? stantially as shown anddescribed.
