UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to roses and especially to a new, original and distinct variety of the class known commercially as hybrid teas and is a variant in that class, being a Rosa wichuraiana hybrid tea hybrid, produced by me and under my direction in the breeding grounds of my research gardens in Little Compton, Rhode Island, by cross pollenation, which can be and has been asexually reproduced.

My new rose is new as to the following characteristics and especially as to their joint association with the characteristics inherited from Rosa .un'charaiana, of hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States;

The yellow to pink shades (ordinary dictionary definition) of its petals, in combination with the unique brilliance thereof and their tendency to hold these colors under exposure,

The novelty and variatio within certain definite limits of the form of the bloom, its character of holding that form for a long time, and the petalage of the flowers;

Its character of fragrance;

Its unusual abundance of flowers, notably after early bloom time and until frost;

The intensity of its remontant and everblooming or reblooming character;

Its character of ascending in height by recurrent branching and progressively longer stems from the base in some instances long enough to be classified as canes;

The character of producing many seven leafleted leaves; which character seldom has obtained on hybrid teas not having Rosa wz'churaiana ancestry, but frequently obtains on flower stems of descendents of Rosa wicharaiana of the dwarf reblooming type;

And especially its characteristic of partial freedom from premature defoliation by blackspot, under certain definite conditions of exposure, without any cultural control.

In the accompanying drawing forming apart of this specification I have shown my new rose in its natural colors, that is, as near as is possible to do so artificially.

My new rose is otherwise described as follows:

Essential information.

Type: Hybrid tea, Rosa wichuraiana hybrid.

dwarf, to ascending to tall to climber, for garden display, cut flower and forcing or growing under glass.

Class: Hybrid tea crossed with Rosa wichuraiana, further restricted by originator to include only those varieties that can survive moderately low sub-zero temperatures.

,Breeding: This variety was produced and bred by me and under my direction by propagation and cross pollenation.

It came into being as a seedling grown from a seed born on a plant of Pink Princess, Plant Patent 459, and the pollen parent of my new rose was Shades of Autumn, Plant Patent 542.

The pollenation that fertilized the seed that grew into my new rose, as well as the pollenation that produced its seed parent were directed by me and were performed by emasculating flowers and placing thereon a bag protecting from self and foreign pollen. These bags were later removed and the flowers were hand pollenated with a camels hair brush and the bags immediately replaced. The date of this pollenation was July 17, 1944. The seed was planted under my direction on December 21, 1944, and the date of the first flower was August 11, 1945.

The plant and flower seemed to me to be of unusual merit and I have since made and directed extensive propagations and tests thereof.

Plants of this variety budded from this seedling on to Rosa multiflora root stock, have after being exposed to moderate sub-zero temperatures, survived and bloomed normally the following season in the hybrid tea manner. The variety has been propagated by budding at Little Compton, Rhode Island, in the months of July and August in 1946-8 inclusive and the characters have successively reproduced, true to the original seeding.

Flower Habit: It blooms out of doors in Little Compton,

beginning about three days prior to the average beginning time of commercial hybrid teas and continues relative to growth of the plant until frost.

Flowers borne: Often one and frequently two or three and occasionally more on each stem, in the usual hybrid tea type of cluster. The pedicels and peduncles are medium large in diameter and medium in length, erect, stiff, almost smooth, free from large prickles and bristles but with a few very small prickles varying to small hairs. Stems are long, diameter medium to large and notably stiff and rigid.

Quantity of bloom: Free, being cumulative in quantity from year to year as the plant increases in size, flowering through the summer.

Fragrance: Distinctive, pleasing China tea in combination with that of Rosa wicharaiana, under favorable environment.

This and other dates herein are approximate.

Before the calyx breaks the size is medium, form moderately pointed, frequently with one or more sepals having foliaceous parts exeight to ten days drop off cleanly, except that occasionally oneor two inner petals. or petaloids cling to turn dull, to fall later. The flower does not ball in wet weather. The flower lasts well, is not affected, at any stage'by moderate cold or hot temperatures, or by humidity -or wet weather. 1 Reproductive organs:
