UNITED STATES PATENT OFFICE BOSE PLANT Josephine D. Brownell, Little Compton, R. I.

Application January 23, 1952, Serial No. 267,778

1 Claim.

My invention relates to rose plants 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 uchurwiana hybrid tea hybrid, in combination with cane growth usually common to climbing roses only, except the canes of my new rose usually bear terminal flowers and recurrent blooms on branches therefrom, often the same year that the canes grow; produced by me and under my direction in the breeding grounds of my research gardens in Little Compton, Rhode Island, by selection of variety variations and 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 wchuraiana, of hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States:

The light yellow and orange 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 variation within certain definite limits of the form of the bloom, its character of holding that form for a long time, and the petallage of the flowers;

Its character of fragrance;

Its unusual abundance of flowers, notable 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 wichura.- ana ancestry, but frequently obtains on ower stems of descendants of Rosa wichuraiana of the dwarf reblooming type;

Under the natural conditions of exposure where this rose was grown it has shown some resistance to black-spot.

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

'I'he raceme pictured represents a cluster of blooms at the terminal end of a cane growth as it blooms the same season as the growth of the cane.

My new rose is otherwise described as follows:

Essential information Type-Hybd tea, Rosa uchuraiana hybrid. climber, for garden display, out flower and forcing or growing under glass.

mcsa- Hybrid tea crossed with Rosa wichufctana, 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. selection and cross pollenation.

It came into being as a seedling grown from a seed borne on a plant of an unnamed seedling not patented and the pollen parent was Climbing Break o Day, Plant Patent No. 696.

The pollenation that fertilized the seed that grew into my new rose, as well as the two previous pollenations that produced its two parents, were directed by me and were performed by emasculating owers 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 the pollenation oi my new rose was July l2, 1948.1 The seed was planted for me and under my direction in December of 1948, and the date of the first flower was July 22, 1949.

I have since made and directed extensive propagations and tests of this plant and flower.

Plants of this variety budded from this seedling on to Rosa multijofra root stock, have after being exposed to moderate `lubzero 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 1950 and the characters have successively reproduced, true to original seedling.

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, frequently two or three and occasionally more on each stem, in the usual hybrid tea type of cluster. and frequently more on climber canes as they grow. Such canes terminate in one or more blooms or clusters of blooms.

l'.lhiu and other dates herein are approximate.

All of the foregoing bloom expression usually obtains the first year after budding on maidens and on two year old plants the first growing season after being transplanted.

The routine performance thereof ls usually as follows. The plant first blooms like a hybrid tea, followed by cane growths in length from about four to ve feet, later more in length terminating 'in blooms. "The hybrid `.tea growth continues to grow rebloom stems in the `hybrid tea manner until frost, also similar stems from the cane growths.

The pedicels and peduncles are medium indiameter and medium in length, erect, stiff, almost smooth, free from large prickles and bristles. Stems are long, medium to small in diameter, and notably stiff and rigid.

Quantity of bloom.-Free, being cumulative in quantity from year to year as the plant increases finalize; owering .through the summer and fall.

Fragrance-Distinctive, pleasing China tea in combination with that of Rosa wichurazcna, underrfavorable environment.

Bud.--Neck normal as ldescribed, opens well,

being little to not at all affected by hot or wet weai'fl'ier or both, as to color and form, except at very'high temperatures the color is less intense andthe `form` of` the petals is less recurled.

Before the calyx breaks the size is medium,

form 'moderately high pointed, the sepais are usually normal and regular, tapering to lanceelate at the apex, Without foliaceous appendages, turning back nearlyperpendicular to the pedicel asthe-bud opens. usually no spurs on sides.

"Color slightly variable dependent upon quality 'oi sun or other light.

The flower lusually varies in size between three `and one-half inches and four and one-half inches in diameter when fully open, petals average around 90. frequently some smaller petals and l petaloids in the center, variable in number.

The iiower opens moderately ovold and semihigh centered. informal, with no display of `stamens and pistils. The petals are variable from obovate to ovate to irregular and frequently with surfaces Vvariously warped and edges especially yof the smaller petals frequently notably irregular. Texture is medium to thick; both sides brilliant. YThe time of opening under favorable conditions is about live days.

The petals are substantial and after about seven days drop off cleanly. except that occasionally one or two inner petals or petaloids cling to turn dull, to fall later. The flower does not ball" in wet weather. The ilower lasts well, is noteected at any stage by moderate cold or hot temperatures, or by humidity or wet weather.

Reproductive organs-stamens quantity variable. medium long, of slightly uneven length.

.Anthersl nearly Marigold Orange at 11/3. Fllaments, nearly Tangerine Orange at 9/ 3.

Pistils are several of nearly even length, aver- Color references to same unless otherwise indicated.

aging about one-half inch long, few in number.

Sepals are persistent and break off easily.

Plant Foliage-Is abundant, of compound leaves of three to five leaflets near the flower, five leaflets lower down the stem and frequently seven leaflets in the middle of the stems and canes and nearer the base. Often. with short narrow leafy formations' variously positioned nea-r the flower as shown. Size of leaflets medium, averaging in i size larger than most varieties of this type and nearly as large as leaets on most hybrid teas.

4Form of leaflets usually ovate with apex moderately acute, baserounded to slightly pointed in some instances with the circumference on one side of the petiolule out of alignment with the other side by about one-sixteenth of an inch or less, margins with slighmy irregular small pointed serrations. petiolules short.

The leaiiets Yaverage in width about oneehalf i to two-.thirds of their length.

Winter resz'staueer-,A notable .characteristic -of this new rose is the resistance to moderatasub- 5 zero temperatures in combination with its hybrid tea character. its climbing habit and its Rosa wichuraiana ancestry. The word temperature" herein refers to the Fahrenheit scale.

Comparisons.-The variety most nearly resembling my new rose is Climbing Break o' Day, Plant Patent No. 696, which lacks some of the hybrid tea. type of rebloom expressed by my new rose.

The color of my new rose is principally light yellow as compared with Climbing Break o Day which is orange to apricot. ordinary dictionary definitions; also, my new rose has a difierent fragrance.

I claim:

The new and distinct variety of rose plant as described and illustrated. characterized by its color pattern, fragrance, form. petaliage, and

6 Lemon Yellow color of its blooms at the terminal end of canes that bloom the same season in which the canes grow; also, by the Wichuraiana, hybrid tea, and everblooming climber characteristics. substantially as described.
