CLIMBING ROSE PLANT Carl W. Chaflin, Ontario, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Calif., a corporation of California Application January 14, 1948, Serial No. 2,252

' 1 Claim. (CI. 47-61) The present discovery relates to a new and distinct variety of climbing hybrid tea rose plant, originating as a bud sport which I found growing on a bush rose of the variety Show Girl (Pl. Pat. #646), in the nursery row at Ontario, California.

This new variety, comparing it with its parent, is characterized aS to novelty, predominantly, by its vigorous climbing habit, the season of bloom and the manner in which the bloomsare produced, and is distinct from all other climbing hybrid tea varieties, as well as all other climbing varieties, so far as I know, in the combination of color, form, and size of the flowers, substantially as specifically described in prior Plant Patent No.

646, dated October 24, 1944, and as illustrated flowers on lateral-growing stems from long canes measuring as much as twelve to fifteen feet in length. As is typical of most climbing hybrid tea varieties originating as sports from bush-"rose types, this new variety produces the major'por tion of its flowers in the spring (usually in April and May) with fewer scattered flowers throughout the remainder of the growing season. Because of these traits, this new variety is suitable for planting adjacent to and covering walls, fences, pergolas, etc., for which the bush rose variety is unsuited.

Asexual reproduction shows that the characteristics hold true through succeeding propagations.

The accompanying drawing illustrates a specimen of this new variety, depicting its climbing habit to a height much beyond that of a six-foot trellis, and the manner in which foliage is produced.

The following is a detailed description of the new variety, all references to color being in accordance with the R. F. Wilsons Horticultural Colour Chart, except where indicated tobe in accordance with Ridgways Color Standards and Nomenclature:

Type: Tall; climbing. Class: Climbing hybrid tea.

Discovery: Sport.

Parent.Show Girl (Pl. Pat. No. 646). Propagation: Holds its distinguishing characteristics through succeeding propagations by budding, the only method tried so far.

Flower Locality where grown: Ontario, California.

Flowers borne: Singly and at times several to stem; in irregular cluster; on normal, medium long stems.

Quantity of bloom: Free; outdoors,

Continuity: Principally one season of bloom in the spring.

Fragrance: Moderate; tea.

Bud:

Peduncle.Medium length; medium caliper; erect; medium rough; few gland-tipped cilia; on some pedicels a few hairs. Color-near Fern Green, Plate 0862/1, Page 186.

Before calyx brealcsSieemedium. Formshort, pointed, without a conspicuous neck; with or without foliaceous appendages, tomentum, gland-tipped cilia on the surface of the bud; often with slender, much cut. bristle-like foliaceous parts extending beyond the tip of the bud equal to one-fourth or more of itslength.

As calyx breaks-Near Rose Madder, Plate 23, page 23. Sepalsinner surface with fine, woolly tomentum on margins of alternate sepals, lined with stipitate and sessile glands.

As first petals open.--Size-medium. Petal does not fold back to any extent until the bud has reached maturity though petals all loosen considerably from the initial tightly clasping state. Form-short; ovoid to globular. C'olor-outside: near Crimson, Plate 22, page 22; inside: Crimson, Plate 22, page 22, and gradually passing into near Crimson, Plate 22/2, page 22.

Opening- -Qpens up well.

Bloom: Size, when fully open-medium to large;

four inches to five inches.

.Petalage.Semi-double (two or even three regularly; three to five petaloids arranged irregularly.

Form.- Cupped to high centerat first; be-

coming open to cupped: petals at first tightlyilat; becoming later, at maturity, loosely fiat to cupped or rolled outward.

Petals: Thick, with inside satiny and outside shiny.

Shape.0utside: round, obovate, mucronate; sometimes scalloped apex .with one or two occasional notches. The center row of petals on some blooms are more scalloped than others. Intermediate: obovate, murconate; scalloped at times with one or two notches. Inside: obovate; mucronate; scalloped seldom, irregular apex. On the petaloids of some blooms is a distinct vegetative ridge running from base to apex, off center, and often a light shade.

C'olor.-Colors may be modified by being pencilled and shaded with other colors.

This description of a newly opened flower was made from a rose grown outdoors and allowed to open three days indoors, in the month of August, at Ontario, California. This description of petals was made from a rose grown in sandy soil:

This description was made from a rose that i was open for three days outdoors in the month of August, at Ontario, California:

Color.--Oatside petaloutside surface: near Phlox Pink, Plate 625/ 1, page 77, to near Phlox Pink, Plate 625/2, page 77, toward apex; inside surface: very little difference from outside surface except occasionally, because of more exposure to sun, the color may be a trifle lighter. This would be then between Phlox Pink, Plate 625/1, page 77, and Phlox Pink, Plate 625/3, page 77. Inside petal-outside surface: Even hue of near Phlox Pink, Plate 625/1, page 77; 1

inside surface: Similar to outside surface or, near Phlox Pink, Plate 625/1, page 77, with a very narrow margin at top of petal of near Phlox Pink, Plate 625/3, page 77. Pencilling is quite pronounced on nearly all petals. Outdoors they become yellowish white about to A," from base when blooms are almost finished.
