Application April 26, 1935, Serial No. 18,437

1 Claim. (01. 47-61) The present invention relates to a new and dis- Bud:

Plant .Pat. 115 2 tinct variety of rose plant and has for its main object the production from a new strain of a truly American hybrid variety of climber by breeding the native species rose Setigera (Prairie Rose) with the Austrian Briar, said new rose having greater winter hardiness than existing types, and novel bloom characteristics of great attraction;

In reference to its hardiness characteristics, this new variety has been found to survive lower temperatures than any of the known Wichuraiana hybrids or so-called hardy climbers.

As regards its bloom characteristics, it is notable that while retaining the native hardiness and blooming habit of its ancestors, in its interbreeding, it has acquired the form and quality of the hybrid tea. It is an extremely prolific bloomer, an established plant being fairly covered with yellow blooms to the extent of almost hiding the foliage, departing, of course, in color from that of either of its parents and thereby presenting another important feature of novelty.

But importantly, a still further essentially novel characteristic of this new variety resides in the habit of blooming twice in the same season, for about six weeks after its first blooming period has passed, a. new abundant crop of bloom appears, lasting several weeks.

The novelty and distinctiveness of this new variety may thus be summarized to exist in the following characteristics, each of which is believed to be independently significant among hybrid climbers:

1. Greater hardiness.

2. Abundance of flowering.

3. Distinctive color of blooms.

4. Habit of blooming twice per season.

Asexual reproduction has shown these characteristics to be fixed.

It may also be noted that this new variety has been awarded the long standing "Replica of Feast Medal, offered for the best development of Rosa Setigera.
