Application January '5, 1954, Serial No. 402,422

1 Claim. (Cl. 47-61) present invention relates to .a .new and distinct variety of rose ,plant of Jthehybrid tea class, which was originated .byme :by crossing the variety Ophelia (unpatented) with the variety Curlywhite .(unpatented).

.As the result of this cross, :Ihave produced anew variety of .rose plant which is particularly characterized as to novelty by the substantiallypure Whitecolor of its blooms which .are comparable to the .color of a white Easter lily when the .rose in full bloom; by its usually long pointed buds; by .the relatively hard petals of its blooms and their resultant long-lasting quality which .is superior to that of any previously known white rose; by its dark green, very thick and leathery foliage and its attendant good resistance to mildew and blackspot; by the relatively short neck of its blooms which results from the fact that the foliage grows to within 3 or 4 inches from the base of the flowers, thereby leaving no naked stems to detract from the decorative beauty of the plant and its flower; and by its habit of bearing blooms on heavy, thick and stilt stems which are capable of enduring the most adverse conditions.

The foregoing characteristics definitely distinguish my new variety from its parents, as well as from all other varieties of its class, and asexual reproduction of my new variety by cuttings, grafting and budding, as performed by me at Decatur, Illinois, shows that these characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawings show typical specimens of my new variety, one of said drawings showing in blackand-White a young bench plant, and the other drawing showing on a somewhat enlarged scale and in color specimens of the flowers and foliage in different stages of development, with the colors depicted 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 my new variety, with color terminology in accordance with Wilsons Horticultural Colour Chart, except where general color terms of ordinary dictionary significance are obvious:

Type: Hardy; bush; greenhouse; seedling; for out flowers and for garden decoration. Class: Hybrid tea. Breeding: Seedling.

Seed parent.Ophelia. Pollen parent.--Curlywhite. Propagation: Holds its distinguish characteristics through succeeding propagations by cuttings, grafting and budding.

FLOWER (Observations made from specimens grown and observed at Decatur, Illinois.)

ColoroutsideChartreuse Green, Plate 663/ 3, page inside-Chartreuse Green, Plate '663/3, page'90.

0pening.0pens .up well; all flowers open slowly;

no sticking of petals; higher than normal temperatures slightly increase opening rate.

Petalage.Semi-double; from 22 to 24 petals; ar-

ranged regularly.

Form.--Flat top, with open cupped center, becoming wider and cupped center giving way to somewhat fiat-line top as outer petals unfurl; petals at first being tightly rolled inward, but becoming later at maturity loosely rolled outward.

Petals:

Texture-Thick; leathery; with both inside and outside satiny.

Shape.Obtuse, with blunt end downward; upper half of petals have wavy or curly edges; all petals have substantially same outline, but inside petals are smaller; color of both faces of petals is the same.

This description of a newly opened flower was made from a rose grown in a greenhouse in the month of October at Decatur, Illinois:

This description was made from a rose that was open for 3 days in a greenhouse in the month of October at Decatur, Illinois:

I claim:

A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particulary as to novelty by the distinctive white color of its flowers, by its relatively long pointed buds, by the relative hardness of the petals of its flowers and their consequent good shipping and keeping qualities, by its abundant and leathery foliage and the consequent good resistance thereof to mildew and blackspot, by the habit of its foliage in growing relatively close to the base of the flowers and the consequent absence of naked stems, and by its habit of bearing flowers on relatively heavy and stifi stems.
