UNITED STATES PATENT OFFICE 1,296 ROSE PLANT Josephine D. Brownell, Little Compton, It. I.

Application March 16, 1953, Serial No. 342,770 1 Claim. (01'. 47-61) 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 wichuraiana hybrid tea hybrid, in combination with cane growth usually common to climbing roses only, except the canes of my new rose plant 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 wichuraiana, of hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States:

The light yellow shades (ordinary dictionary definition) of its petals, in combination with the soft 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 everbloom- I ing 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 wichuraiana ancestry, but frequently obtains on flower stems of descendants of Rosa wichumiana of the dwarf reblooming type;

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

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.

The flowers pictured represent a portion of a cluster of blooms at the terminal end of a cane growth as it blooms the same season as thegrowth of the cane.

My new rose is otherwise described as follows:

Essential information Type.-I-Iybrid tea, Rosa wichuraiana hybrid;

not having Rose hybrid tea to ascending to tall to climber, for

garden display, cut flower and forcing or growing under glass.

,ing in blooms;

Class-Hybrid tea crossed with Rosa wichuraz'ana, 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 0 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 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 the pollenation of my new rose was July 3, 1948. The seed was planted for me and under my direction on December 22, 1948, and the date of the Flower Habit.-It blooms 0a 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.0ften one and frequently two or three and occasionally more on each stem, in the usual hybrid tea type of cluster. And frequently later on climber canes as, they mature. Such canes terminate in one or more blooms or clusters of blooms.

The foregoing bloom expression on the hybrid tea stem growth 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 is usually as follows. The plant first blooms like a hybrid tea, later by cane growths in length from about four to five feet, later more in length terminat- The hybrid tea growth continues to grow rebloom stems in the hybrid tea manner untilfrost, also similar stems from the cane growths.

1 This andbther dates herein are approximate.

The canes seek to grow at various angles of about 85 from. the horizontal.

The hybrid tea growth can usually be differentiated from cane growth by the diameters thereof and otherwise by characteristics common to each.

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

Quantity of bZoom.Free, being cumulative in quantity from yearto year as the plant increases in size, flowering through the summer and fall.

Fragrance-Distincive, pleasing China tea in combination with that of Rosa wichumi'ana, under favorable environment.

Bud.Neck normal as described, opens well, being little to not at all alfected by hot or wet weather or both, as to color and form, except at very high temperatures the color is less intense and the form of the petals is less recurled.

Before the calyx breaks the size is medium, form moderately high pointed, the sepals are usually normal and regular, tapering to lanceolate at their apex, occasionally with foliaceous appendages, turning back nearly perpendicular to the pedicel as the bud opens, usually no spurs on sides.

Color of the bud as the calyx opens, sides of petals Empire Yellow at 603/1 or a little lighter, shading variously to nearly Amber Yellow at 505/1; color reference to English Horticultural.

Color Chart.

Bloom.-Color softens slowly'both sides to Amber Yellow and later to nearly Amber Yellow at 505/3.

Color slightly variable dependent upon qual ity of sun or other light.

The flower usually varies in size around three and one-halfinches in diameter when fully open,

petals average around 75, frequently some smaller petals and petaloids in the center, variable in number.

The flower opens moderately oviod and semihig-h' centered, nearly formal, with no display of stamens and pistils until fully open. The petals are variable from obovate to ovate, a few irregular and some with surfaces slightly warped. Texture is medium to thick; both sides softly brilliant. The time of opening in favorable cone-- ditions is about six days.

The petals are substantial and after. about seven days drop oif 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 flower lasts Well, is not affected 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.

Anthers, nearly Marigold Orange at 11/3. Filaments, nearly Tangerine Orange at 9/3. Number variable around 30.

Pistils are several of nearly even length, averaging about one-half inch long, number normal.

Sepals are persistent and break ofi easily.

Plant FoZiage.-ls abundant, of compound leaves of three to five leaflets near'the flower, five leaflets lowerdown the stem and frequently seven leaflets in the middle of the stems and canes and nearer Color reference to same unless otherwise-indicated.

the base. Often with short narrow leafy formations variously positioned near the flower as shown. Size of leaflets medium, averaging in size same as most varieties of this type and as large as leaflets on most hybrid teas. Form of leaflets usually ovate with apex moderately acute, base rounded 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 slightly irregular small pointed serrations, petiolules short.

The leaflets average in width about one-half of their length.

Color of leaflets on. the upper surface is slightly variable from Scheeles Green at 860, irregularly shaded with Spinach Green at 0960/1, with reverse side nearly Asphodel Green frequently overlaid with trace of Dahlia. Carmine, the. last two color references are to Robert Ridgway Color. Standar' s.

The rachises are medium, moderately narrow to slender, upper side smooth except some very' short hairs on edge. Under side moderately smooth, usually three to five short prickles.

Stipules are long, averaging about one inch long or a little less, with sharp points, the upper edges of which normally form an angle of about degrees.

Habit, hybrid tea, becoming bushy to tall; upright, compact, later climbing by canes and more cumulative in growth from year to year than the normal hybrid tea rose plant, and with canes that branch to normal height of average hardy climbenby stems from the base andby rebranching. and. growth and enlargement and extension of the stems from the base. The growth is mod erately free at first, developing more rapidlyafter one or two years under favorable vegetative opportunity.

Color of mature stems is Scheeles Green at.

860/3, shading variously lighter and. also occasionally with slight overlay of Spinel Red at 0023/1 variable in intensity, usually more pronounced on the sunny side.

Prickles, several, frequently two to four between leaves, averaging in length about one.- quarter to one-third inch, shading from Crimson at 22 to lighter at the base, turning. lighter throughout and later to nearlycol'orless.

Winter Tesistance.A notable characteristicof this new rose is the resistance to moderate subzero 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 0 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 0 Day which is Orange to Apricot, ordinary dictionary definitions.

I claim:

The new and distinct variety of roseplant as described and illustrated, characterized by its color pattern, fragrance, form, and yellow color of its bloom at the terminal end of canes that bloom the same season in which the canes grow; also, by the Wichuraiana, hybrid tea, and overblooming climber characteristics, substantially as described.
