ROSE PLANT Filed April 20, 1959 United States Paten'tO" ROSE PLANT Herbert C. Swim, Ontario, Califi, assignor to Armstrong Nurseries, Inc., Ontario, Califi, a corporation of California Application April 20, 1959, Serial No. 807,740 1 Claim. (Cl. 47-61) The present invention relates to ,a new and distinct variety of rose plant of the floribunda class, which was originated by me by the deliberate planting and growing of seed derived from open-pollinated flowers of an unnamed seedling which is the subject of my copending plant patent application Serial No. 785,770, filed January 8, 1959.

' The general objective of my efforts in this connection was to produce an improved pink floribunda rose which maintains the attractive bud and half-open flower form of the parent variety, recombined with the greater floriferousness and double petalage of the grandparent variety, Pinocchio (Plant Patent No. 484), while at the same time having the flowers attractively and evenly spaced over a healthy, vigorous, bushy, compact plant. Objective was substantially achieved along with other desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parent, as well as from all other varities of which I am aware:. A

(1) A vigorous, compact, bushy, much-branched habit of plant growth, with the plant having a medium size;

(2) Attractive, dark green, disease-resistant foliage of medium size;

(3) Flowers borne abundantly on stems of from short to medium length in small clusters which are evenly spaced over the plant in an attractive manner;

(4) Very double flowers of medium size, and having an attractive urn-shaped bud form which opens into a well-formed symmetrical open flower; and

-(5) A flower color which is an attractive and distinctive shade of light red or dark pink which tends to fade evenly to a lighter color as the flower ages.

In comparison with its parent variety, the plant of the new variety is of medium size whereas that of the parent is very large; the flowers are borne somewhat more abundantly and in somewhat larger clusters; the flowers are very double, instead of semi-double or double as in the parent variety; and the flower color is a dark pink or light red, whereas that of the parent is a lighter pink color.

Asexual reproduction of my new variety by budding, as performed at Ontario, California, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety, in different stages of development and as depicted in color as, nearly true as it is reasonably possible to make the same in a color illustration of this character.

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

I claim:

A new and distinct variety of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by its unique combination of vigorous, compact, bushy, medium sized and much-branched plant habit, attractive, medium sized, dark green, disease-resistant foliage, a habit of bearing flowers abundantly on stems ranging from short to me dium length and in small clusters evenly spaced over the plant, said flowers being of medium size and very double, and being urn-shaped in the bud stage, but opening into a well-formed symmetrical open flower, and a distinctive light red or dark pink general color tonality of the flowers, with a tendency to fade evenly to a lighter color as the flowers age.
