UNITED STATES PATENT OFFICE ROSE PLANT Josephine D. Brownell, Little Compton, R. L Application May 22, 1951, Serial No. 227,576

1 Claim.

1 My invention relates to roses and especially to a new, original and distinct variety of the class lmown commercially as hybrid teas and is a variant in that class, being a Rosa wichuraianahybrid 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 char- 1 acteristics and especially as to their joint association with the characteristics inherited from Rosa wicharaiana, of hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States:

The pink to 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 notable resistance to blackspot;

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, at bloom time and 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 wichuraiana ancestry, but frequently obtains on flower stems of descendants of Rosa wichuraz'ana of the dwarf reblooming type;

And especially its characteristic of 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.

My new rose is otherwise described as follows:

Essential information Type: Hybrid tea, Rosa wichuraiana hybrid, dwarf 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 under my direction by propagation and cross pollenation.

It came into being as a seedling grown from a seed born on a plant produced by me and under my direction by cross pollenation between General J ackqueminot" (not a patented variety) as pollen parent and the climbing rose Dr. W. Van Fleet (not a patented variety) as seed parent; and the pollen used to produce my new rose plant was that of the variety produced by me and under my direction Lafter," Plant Patent No. 955.

The pollenation that fertilized the seed that grew into my new rose, as well as the two previous varieties mentioned were directed by me and under my direction 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 3, 1947 The seed was planted under my direction on December 18, 1947, and the date of the first flower was July 14, 1948.

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

Plants of this variety budded from this seed- 4 ling 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 1948 and 1949, inclusive and the characters have successively reproduced, true to the original seedling.

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 bomez-Often one and frequently two or three or more on each stem, in the usual hybrid tea type of cluster. The pedicels and peduncles are medium small in diameter and medium in length, erect, stiii', smooth, free from prickles and bristles. Stems are long, diameter medium and notably still and rigid.

This and other dates herein are approximate.

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 wichuraiana, under favorable environment.

Bud:--Neck normal as described, opens well, be-

ing little to not at all affected 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 pointed, frequently with one or more sepals having foliaceous parts extending beyond the apex of the calyx up to about one half of an inch, the number and size of the foliaceous parts being variable, otherwise the sepals are usually normal and regular, tapering to lanceolate at their apex, turning back nearly perpendicular to the pedicel as the bud opens.

Color of the bud as the calyx opens: outside of petals, top, Marigold Orange at 11/2, this reference and the following except as otherwise noted is to British Horticultural Color Chart: edged Fire Red at 15/1 shading down to nearly Cadmium Orange at 8/1: inner side, top, Ponpv Red at 16/1, base shading to Indian Yellow.

Bloom:As the bud opens and the flower develops to maturity the colors start as above and slowly soften, maintaining for an unusually long time the orange and yellow shades, above described.

The flower usually varies in size from four to live inches in diameter when fully open, petals average between 35 and, 50, freouently some smaller petals and petaloids in the center. variable in number.

The flower opens high centered, informal, recurled, side curled, warned with terminal edge often waved and crinkled closely resembling rufiies with late display of stamens and pistils. The petals are variable from obovate to ovate to irre ular and frecuently with surfaces of the smaller petals frequently notably irregular. Texture i medium to thick both sides brilliant with slight veining which is not prominent. The time of opening in favorable conditions is four to six days.

i The petals are substantial and after about flve to six days drop ofi 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 aflected at any stage by moderate cold or hot temperatumes, or by humidity or wet weather.

Reproductive organs:

Stamens, quantity variable, or slightly uneven length.

Anthers, Burnt Orange 014/3.

nearly Maize Yellow at 607/1.

Plstils are several of slightly uneven lengths,

averaging around one-half inch long.

Ovaries are usually all inclosed.

Hips frequently develop to ovoid to globular, color comparable with that of leaves with variable colored overlay on the side exposed to the sun, moderately smooth; walls, thin, fleshy, medium in size.

Sepals are pesistent and break off easily.

Filaments,

Plant Foliagez-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 stem and nearer the base. Size of leaflets medium, averaging in size about half way between the average hybrid tea and the Rosa wichuraiana leaflets. As the plants develop in size some of the leaflets develop to one half larger than the size described above. Form of leaflets usually ovate with apex moderately acute, base rounded frequently slightly acute, margins with pointed serrations, petiolules short.

The leaflets average in width about twothirds of their length.

Color references hereinafter are to Robert Ridgway Color Standard.

Color of leaflets on the upper surface is slightly variable from Dark Dull Yellow Green, with reverse side nearly Asphodel Green.

The rachises are medium, moderately narrow to slender, upper side smooth except some very short hairs on edges. Under side moderately smooth, usually 3 to 5 short prickles.

Stipules are medium, averaging about onehalf of an inch long, with sharp points proportionally longer than usual, the upper edges of which normally form an angle of about 60 degrees.

Habit, dwarf; upright, compact, due to constitutional factors inherited from Rosa wichamz'ana; more cumulative in growth from year to year than the normal hybrid tea rose plant, by stems from the base and by rebranching and growth and enlargement and extension of the stems from the base. The growth is moderately free at first, developing more rapidly after one or two years.

A notable difference from most rose plants is in the manner of growth of the stems. The leaves being closer together on the stems more eyes than normal are produced and more stems grow therefrom, thus increasing the production of blooms.

Color of mature stems is the same as that of the upper surface of mature leaves, shading variously lighter.

Prickles, several, frequently two to four between-leaves, averaging in length about onequarter inch, shading from the color of the stems to lighter, turning lighter throughout and later to nearly colorless. The entire plant is notably free from hairs.

Disease resistance: As a more exact description Winter resistance: A notable characteristic of this new rose is the resistance to moderate sub-zero temperatures in combination with its hybrid tea character and its Rosa wichuraiana ancestry. This variety with grafted bud and plant above that bud entirely exposed above ground to moderate sub-zero temperatures survived and bloomed normally the following sea- Tin Toes (Plant Patent 849) is a Rosa 6 wichuraiana hybrid of Orange tones. has not so many petals, and the form 0! the flower is much more formal.

I claim:
