ROSE PLANT 2 Sheets-Sheet 2 Filed May 11, 1962 2,242 ROSE PLANT Gordon J. Von Abrams, 3463 NW. Savier St., Portland, Oreg. Filed May 11, 1962, Ser. No. 194,207 1 Claim. (Cl. 47-61) The present invention constitutes a new and distinct variety of rose plant of the commercial grandiflora class, originated by me by cross-pollinating the variety Carrousel (Plant Patent No. 1,066) with the variety PD N0. 5361-A (previously originated by me, not patented and not in commerce).

The following objectives, for which this breeding was planned and executed, were achieved:

(1) Tall, very vigorous plant habit;

(2) Exceptional floriferousness;

(3) Very bright red flower color; and

(4) Flowers borne on long secondary stems, some borne singly, but most borne in clusters of several to many on each main stem.

The symmetry of flower form in relation to the regularly rufiied petals, in addition to the flower color, type of inflorescence and general plant habit, and in addition to the particular complement of other phenotypic characteristics, makes this new variety worthy and distinct from other varieties currently in commerce or otherwise known to me.

The new variety differs from its seed parent, Carrousel, in the following respects:

The flower color of the new variety is somewhat brighter, not as dark, as that of Carrousel;

The petals are more numerous, more ruflied but more regular in outline, more symmetrically arranged, and the inside petals of the opening flower are less cupped;

The stamens are fewer in number;

The leaf is slightly less accuminate; and

The thorns are generally more numerous than on Carrousel.

The new variety shows little phenotypic resemblance to its pollen parent, PD No. 6361-A, differing most obviously in having a taller and more upright plant habit, fewer petals, brighter flower color, more regular flower form, and less disease resistance than the pollen parent.

The pollination from which this new variety resulted was performed by me in 1954. The variety was first asexually reproduced in 1956 by bud-grafting, and has retained its distinguishing characteristics through the succession of such vegetative propagations since that time.

The accompanying illustrations were made in September 1961, of specimens grown outdoors at Scappoose, Oregon. The illustration in color shows vegetative and reproductive parts of the new variety in various stages of development. The black-and-white illustration shows a typical inflorescence of the new variety.

The following detailed description of the new variety was prepared in August 1961, from specimens propagated and grown outdoors at Scappoose, Oregon. To the best of my ability, colors, wherever pertinent, have been defined with reference to the following color standards:

(1) Ridgway, R.; Color Standards and Color Nomenclature, Washington, D.C., 1912.

(2) Wilson, R. F.; Royal Horticultural Society Colour Chart, England, 1940.

Reproductive Parts Quantity of bloom: Very abundant.

Continuity of bloom: Nearly continuous during growing season.

Inflorescence: Flowers borne sometimes one, but more often several to many per main stem; on moderately strong, medium to long secondary stems.

Before calyx breaks.-Size-medium. Formmedium tapered point; terminal appendages usually medium aristate or rarely long foliaceous.

As calyx breaks.-Exposed petal color near Purple Madder (Wilson, 1028, p. 181) or darker, to near black.

As first petal opens-Petal color: outer surfacedarker and somewhat bluer than Cardinal Red (Wilson, 822, p. 168) irregularly flushed darker,

but clearer and deeper than Cardinal Red (Wilson,

Fragrance.-Faint.

Petals:

Subslance.Medium thick; firm; flexible.

Texture-Outside shiny; inside velvety.

Shape and size in open flower.Petals generally ruflied, as described above. Outside petal-broadl obovate (i.e.S cm. broad by 4.5 cm. long); apex rounded but irregular. Intermediate petalobovate (i.e.--4 cm. broad by 4.5 cm. long); apex rounded or irregularly notched. Inside petalgenerally obovate, but smaller and somewhat irregular or contoured.
