United States Patent ROSE PLANT Robert V. Lindquist, Hemet, Califl, assignor' to Hemet Wholesale, Hemet, Califl, a partnership Application January 5, 1956, Serial No. 557,618

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant which originated as a sport of the variety Eutin (unpatented), and is distinguished from the latter by its climbing habit of growth. The new variety was discovered by me in a cultivated block of Eutin roses which were being grown under my direction and supervision at Hemet, California.

At the time of my discovery, my attention was attracted to the new variety by the unusually vigorous and climbing habit of a particular plant of the Eutin block noted above. Upon closer examination thereof, I found that the parent variety had sported, and I thereupon promptly took steps to preserve, asexually reproduce and observe the sport for the purpose of determining whether its climbing habit was fixed and was transmissible by asexual reproduction. The climbing habit was fully confirmed by such observations and by asexual reproduction by budding, as performed by me at Hemet, California, and I have established that the climbing habit of growth of the new variety comes true to form and is transmissible through succeeding propagations.

In addition to being generally similar to the parent variety Eutin, except that the latter is a bush rose and so far as I am aware has never exhibited any tendency toward a climbing habit, my new variety further differs in a few minor respects from the parent variety in that the flowers of the new variety are produced in smaller clusters and are borne on shorter stems than those of Eutin.

In view of the general similarities, except as noted in the foregoing, it is unnecessary to describe or illustrate the new variety in detail herein, but for convenience, the accompanying drawing illustrates in black-and-white a typical specimen plant of the new variety, as well as typical specimens of the vegetative growth and flowers thereof in different stages of development and on a somewhat enlarged scale.

The following is a brief description of the new variety, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as Wilson) and Robert Ridgeways Color Standards and Nomenclature (hereinafter abbreviated as Ridgeway), as indicated:

This description of a newly opened fiower was made from a rose grown outdoors in the month of September, at Hemet, California:
