Filed Mar. 13, 1964, Ser. No. 351,878

1 Claim. (Cl. Flt-28) varieties of which we are aware:

(I) A relatively low growing and compact habit of growth;

(2) The production of flower buds of long-pointed to urn-shaped form;

(3) A flower size ranging from small to medium, with semi-double petalage;

(4) A habit of bearing the flowers in clusters composed of a relatively large number of flowers per cluster as compared with other varieties in this class having red colored flowers;-

(5) Profuse production of flowers, with a consequent mass eifect which substantially covers the plant;

(6) A distinctive and attractive Bright Red general color tonality of the flowers;

(7) Long-lasting flower qualities; and

(8) Relative freedom from disease, and more particularly from powdery mildew.

Plant Pat. 2,538 Patented June 15, 1965 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 our new variety, with color terminology in accordance with the Nickerson Color F an, published by Munsell Color Company, Incorporated, of Baltimore, Maryland, except In comparison with its seed parent Spartan, the plant a of our new variety is substantially lower growing; it bears many more flowers, with the flowers tending to substantially cover the plant at the peak of the bloom periods; the flowers are borne in clusters or sprays composed of a greater number of flowers on the average; the flowers are somewhat smaller in size, ranging from about 2% inches to 2% inches in diameter, as compared with 3 inches to 3 /2 inches in the case of the flowers of Spartan; the

flowers of our new variety have less petalage, ranging from 25 to 30 petals, as compared with 30 or more petals in the case of the flowers of Spartan; and the flower color of our new variety is darker, ranging from Medium Red to Dark Red, as distinguished from the Orange-Red to Reddish-Coral flower color of Spartan.

As compared with the pollen parent Garnette our new variety has a lower growing habit; the flower stems are substantially longer, with little evidence of the zig- Zag effect that is characteristic of the flower stems of Garnette; the flower buds have a form ranging from long-pointed to urnshaped, as compared with the shortpointed to nearly globular flower buds of Garnette; the flowers have a substantially greater diameter but substantially fewer petals than those of Garnette in which the petalage averages about 50 petals per flower; and the flowers have a Bright Red color which is undiluted or altered with other colors, thus giving a distinctive and attractive mass eifect without the characteristic Blue or Magenta shadings in the reddish flower color of Ga-rnette.

Asexual reproduction of our'new variety by budding, as performed at Chino, California, shows that the aforementioned characteristics and distinct-ions 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 our new variety in where general color terms or ordinary dictionary significance are obvious:
