UNITED STATES PATENT OFFICE Frederick-H. Axell, Mountain View, Calif., assignor to J. A. Axell & Company, San Francisco, Oalif., a partnership Application October 14, 1947, Serial No. 779,783

This invention relates to a new rose plant variety particularly adapted for greenhouse forcingto supply blooms to the cut-flower trade. The novel characteristics of this rose include a new and pleasing color.

This new" rose is a sport of a rose known as Pink Delight, an unpatented hybrid tea rose believed to be of European origin, commonly grown in greenhouses and furnishing blooms used by florists throughout the United States. Such parent rose is not the Pink Delight polyantha, a single petalled variety brought out by Laxton in 1922, and all references hereinafter to Pink Delight mean only the hybrid tea greenhouse rose bearing such name. Both the newrose and its parent rose have extreme usefulness in that they permit the continuous supply of blooms to florists during a period between September and July 1 of each season, when blooms on garden roses are scarce in many parts of the country.

A feature of importance of this sport of Pink Deligh is its soft pink self-color markedly distinguishing it from the deeper, purplish pink of Pink Delight. This color lends the new rose to a range of florist uses for which Pink Deligh would not be acceptable. Thus the color of Pink Delight in bud form is slightly deeper than Rose color as shown by Plate XII of Ridgways Color Standards and Nomenclature, whereas the bud of the new rose is Thulite Pink (Plate XXVI). The open flower of Pink Delight is approximately Mallow Purple (Plate XII), whereas the new rose in open flower is slightly lighter than Deep Rose Pink (Plate XII). However, the new rose includes the other good features which make its parent, Pink Delight, valuable for supplying the florist trade, such as good growth characteristics, free habit of bloom, and long lasting qualities of bloom.

The new rose' has been asexually reproduced and its distinctive characteristics have come true to form in the reproductions.

The accompanying illustration shows four blooms of the new rose, including a bud, a partially opened flower and a fullyopened flower. Since the illustration cannot well depict the exact, pleasing coloring of the natural blooms, reference is made to the description herein where the colors are specifically set forth.

The following is a detailed description of the 1 Claim. (01. 47- -61) 2 new rose; and the colors designated were taken from Ridgways Color Standards and N0menclature:

General information Type: Bush plant particularly adapted for greenhouse growing to supply flowers for the cutflower trade.

Class: Hybrid tea.

Breeding or discovery: By Frederick H. Axell at Sunnyvale, California.

Sport.-Of an unpatented rose known as Pink Delight and discovered in 1944 in the greenhouse planting of Pink Delight stock.

Propagation-By budding, conducted at Sunnyvale, California, by Frederick H. Axell. The variety has retained its distinguishing characteristics through succeeding propagations.

Flower Locality where grown: Sunnyvale, California.

Flowers borne: Singly to the stem and on strong,

long stems.

Quantity of bloom: Abundant under greenhouse conditions.

Continuity: Continuous.

Fragrance: Moderate tea.

Bud: Long peduncle. Bud is slender, erect, light green with few green prickles.

Before calyx breaks, bud is small, globular, with a conspicuous neck, with foliaceous appendages on the surface of the bud, such foliaceous parts extending beyond the tip of the bud equal to one-quarter of its length.

As calyx breaks, the color is slightly deeper than Rose color (Plate XII) As first petal opens its size is medium and its form is long and ovoid; the outside color is Thulite Pink (Plate XXVI) and the inside It opens up' and becoming later, at maturity. loosely rolled outward.

Petals: Thick, leathery, with inside velvety and outside satiny.

Shape-Outside petals are round, with one notch, and intermediate petals are round.

Colon-The colors are modified only by a small blaze of Lemon Yellow (Plate IV) at the base of the inside surface of each petal, this blaze of color shading into a narrow margin of white, but these colors are barely discernible unless the petals are removed from the flower. The colors both in the newly opened flower and a flower open for three days, grown in a greenhouse, are as follows: Outside petaloutside surface: Thulite Pink (Plate XXVI); inside surface: Deep Rose Pink (Plate XII). Intermediate and inner petals-outside surface: Deep Rose Pink (Plate XII); inside surface: Rose Color (Plate XII).

The general color effect is Deep Rose Pink (Plate XII) in the newly opened flower, with the color only a shade lighter after the flower is open three days.

Behavior: Petals hang on for life of bloom and then drop off cleanly.

sFlowcr lbrigtwliyi days on bush under greenhouse conditions; cut flowers kept at living room temperature 4 days. 7

Quantity of bloom: Approximately thirty blooms per plant a season for cutting purposes.

Time of bloom: In greenhouse the peak bloom occurs between September and July 1 of each season, but flowers are available continuously.

Reproductive organs Stamens: Few, arranged irregularly, mixed with petaloids. Filaments: Medium, pinkish, with anthers. Anthers; Medium, reddish brown, open at various times, Pollen: Moderate yellow.

Pistils: Many.

Styles: Uneven, short, thin and bunched.

Stigma: Yellow red.

Ovaries: All enclosed in calyx.

Hips: Very globular, green, very smooth and with thin walls.

Sepals: Long and spear shaped.

Having thus described my rose, 111 claim:

A new and distinct variety of rose. plant, retaining the characteristics of, growth, ireehabit of bloom, and long lasting qualities of bloom making its parent variety suitable for greenhouse forcing to supply blooms to the cutrflower trade,

and-characterized as to novelty by differing. from such parent variety in the unique color of its flowers substantially as shown and described.
