Application December 17, 1947, Serial No. 792,262

1 Claim.

My present invention relates to a new and distinct variety of polyantha rose plant, with particular reference to its manner of growth. It originated from a cross between Dainty Bess and the hybrid seedling Rosa gigantea, with Mme. Cecile Brunner as one of its earlier progenitors.

Although this new variety is more like Mme. C. Brunner than any other variety known to me, it difiers greatly, particularly in its manner of growth. Unlike Mme. C. Brunner, its growth is erect.

The flower of my new variety is larger and deeper in color, and the bud is larger and more pointed than Mme. C. Brunner. It is truly a remontant bloomer and is especially adapted to forcing because of its length of stem and excellent keeping qualities.

Accompanying illustrations show in approximately true colors, three typical specimens of the flower of this new variety in various stages of opening, together with portions of the foliage and stems.

In the following detailed description, the usual dictionary meaning of the color nomenclature is intended except that where plate references are given Ridgways Color Standards and Nomenclature are indicated.

The plant Growth habit: Very erect growth, with long canes.

Blooming habit: Truly remontant.

Stipules broad and long.

Bud:

Stigma dull red.

Stamens-Filaments light red. Anthers yellow in bud, changing to dull red. Pollen yellow.

Fruit.--None.

Comparison The known variey which is most like my new variety is Mme. Cecile Brunner. The chief differences are as follows:

1. My variety grows erect, unlike C. Brunner.

2. My variey has longer canes.

3. My variety has longer and more pointed bud.

4. Flower of my variety is a deeper pink color.

5. Flower of my variey is slightly larger.

6. Flower of my variety has much better keeping qualities.

Having thus disclosed my invention, I claim:

The new and distinct variety of polyantha rose plant of the Mme. C. Brunner type, substantially as herein shown and described, characterized particularly by its erect growth; its long canes; its long pointed bud; and its deep pink flowers of good petalage and excellent keeping qualities.
