ROSE PLANT Filed June 14, 1967 United States Patent 2,8 ROSE PLANT David L. Armstrong, Ontario, Califi, assignor. to.v Armstrong Nurseries, Inc., Ontario, Califl, acorporation of California Filed June 14,1967, Ser. No. 646,132 1 Claim. (Cl.- Plt.24)

The present invention relates; to. a new and distinct variety of rose'plant of; the floribunda (hybrid-polyantha) class, which was originated, by. me by crossing the rose variety known as. Fandango (Plant Patent: No. 894) with thevariety known as Pinocchio(Plant Patent No. 484), the former being the seedparent and. the latter being the pollen parent.

The new variety resulted from an extensive breeding program having for its objective to produceimproved large-flowered florib-unda rosevarieties which bear-flowers of various colors. This objective was fully achieved, as evidenced'by the following unique combination of. characteristics which are outstanding inthenew. variety and which distinguish it from its parents, as well asfrom all other varieties of which I am aware:

l) A vigorous plant havingan attractive, semi-upright, bushy and well-foliaged plant'habit;

(2) A very floriferous habit, with the fiowersusually borne in small clusters onshorti'tomedium lengthstems typical of a good floribunda habit;

(3) Excellent urn shaped buds. and. an attractive highcentered open flower form;

(4') Medium sized flowers of: quite'doublepetalage; and

(5) A distinctive light. to medium yellow flowercolor which remains-attractive at all times.

In comparison'with its seed parent, Fandango, the new variety has a less vigorous but more bushy plant habit, its flowers are usually borne in small clusters contrary to the usually single flowers of this parent; theflowers are considerably more double; and the flowers are yellow in color instead of red like those of this parent.

As compared with its pollen parent, Pinocchio, the new variety bears larger flowers than those ofthis parent; and the flowers are yellow in color instead of pink or pink blended like the, flowersof this patent.

Asexual reproduction of my new 'variety by budding, as performed at Ontario, Calif, shows that the foregoing characteristics and distinctions come trueto 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 abbreviated (W)) and Robert Ridgways Color Standards and Nomenclature (hereinafter abbreviated (R) as indicated:
