Feb. 16, 1965 ARMSTRONG Plant Pat. 2,474

ROSE PLANT Filed Jan. 3, 1964 Jab 2,474 ROElE PLANT David L. Armstrong, Ontario, Calih, assignor to Armstrong Nurseries, inc, Gntario, Califl, a corporation of California Filed Jan. 3, 1%4, der. No. 335,704 1 Claim. (Cl. Plt.-2tl) The present invention relates to a new and distinct variety of rose plant of a class falling midway between the hybrid tea and fioribunda classes, said new variety having been originated by me by crossing the variety known as Roundelay (Plant Patent No. 1,280) with the variety known as El Capitan (Plant Patent No. 1,796), the former being the seed parent, and the latter being the pollen parent.

This new variety was selected as one of the outstanding results of an extensive. breeding program conducted by me with the objective of producing improved rose varieties falling in a class between the hybrid tea and floribunda classes, with particular emphasis on doubleness of flour form, brightness of flower color in the red and orange-red color range, combined with good floriferousness. In the new variety which is the subject hereof, these objectives have. been fully vachieved, along with other desirable improvements, asevidenced by the following characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties or" which I am aware:

(1) Vigorous, bushy, well branched and attractive plant habits;

(2) Glossy, disease-resistant foliage; v I (3) Abundant flowers for its class, said flowers being borne both singly and in small clusters on stems of medium length and being evenly distributed over the plant;

(4) A quite double flower form and of medium size,

with a combination of short flower petals and increasing tendency toward thecenter to stand upright and ruffle and told inward, sometimes covering the center and giving an over-all attractive rufiled effect, reminiscent of carnation flowers;

(5)A distinctive, attractive and extremely bright and glowing orange-red flower color which particularly stands out and presents a striking contrast against the glossy greenfoliage; and 1 (6) A very long flower life as compared with most rose'ilowers, which is attributable to the great substance of the individual flower petals.

In comparison with its seed, parent Roundelay, he new variety has only a slight suggestion of urn-shaped buds, with" the open flowers being more cupped and the individual petals being, rather short and tending to stand upright toward the center, contrary to the good urnshaped bud form in the parent variety, with the open flowers of the latter having their petals laying back more; also, the orange-red colorof the flowers of the new variety is distinctly different from that of the parent variety which is more red or dark red.

As compared with the pollen parent El Capitan, the vigor of the new variety is somewhat less than that of this, parent, which is extremely vigorous; the new variety has only a tendency toward urn-shaped buds, whereas the buds of this'parent are nearly perfect urn-shaped; the fiowersof the new variety 'aresmaller and more double; the flower form .is characterized by a tendency offlthe rather short petals to stand more vertically toward the center, with considerable ruffiing of the inner petals, contrary to the considerably larger petals of the flowers of El Capitan in which the petals are less rutiied; and the flower color of the new variety is orange-red, which is distinctly different from the red flower color of this parent.

Plant Pat. 2,474 Patented Feb. 16, 1965 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 th same in a color illustration of this character.

The following is a detailed description of the new vs y, with color terminology in accordance with Robert P. Wiisons Horticultural Colour Chart (hereinafter abbreviated (W) and Robert Ridgways Color Standards and Nomenclature (hereinafter abbreviated (R), as indicated:
