1 Claim.

wichuraiana, of hardiness, or immunity from" serious injury on account of cold temperatures prevailing in certain parts of the norther United States;

The red to orange 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 variation within certain definite limits of the form of the bloom, it character of holding that form for a long time and. the: I

petalage of the flowers;

Its character of fragrance;

. Its unusualabundance 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 leafs leted leaves; which character seldom has obtained on hybrid teas not having Rosa wz'churaiana ancestry, but frequently obtains on flower stems of descendants of Rosa wichuraiana 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 drawings 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 wichumiana hybrid, dwarf to ascending to tall to climber, for garden display, cut flower and forcing or growing under glass.

Glaser-Hybrid tea crossed with Rose wwwlow 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, beingan unnamed seedling, and the pollen parent of my new rose was Stargold.

The pollenation that fertilized the seed tha grew into my new rose, as well as the pollenation 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 cameljs hair brush and the bags immediately replaced. The date of this pollenation was July 3, 1936.* The seed was planted under my direction on December 1, 1936, and the date of the first flower was July 16, 1937.

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 andbloomed 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 1937-40 inclusive and the characters have. successively reproduced, true to the original seedling.

FLOWER H abz'tz-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 in diameter and 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 slightly large and notably stifi and rigid.

Quantity of bloom-Free to abundant, being cumulative in quantity from year to year as the *This and other dates herein are approximate.

plant increases in size, notably free flowering through the summer, being of greater bloom quantity than that of tender hybrid teas known to me.

Frctgrance.-Strong, distinctive, pleasing china tea in combination with that of Rosa wichuraiana and musk, under favorable environment.

Bud.-Neck normal as described, opens well, being 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,

more sepals having foliaceous parts extending beyond the apex of the calyx up to about three-.

quarters of an inch, the number and size -of the foliaceous parts being variablejand.frequently" having one narrow, pointed, serrate appendage on each side of the sepals, 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; both sides of petals variable between Vermilion at (2) (reference to color chart, The Rose Manual 1930 by Dr. J. H. Nicolas, opposite page 264) and Flame at (1), and Peach at (l), slightly overlaid, with Nasturtium at (2) (reference same, opposite page BZoom.As the bud opens and the flower develops to maturity the color both sides of the petals slowly changes toward Coral at (2) (same reference). The petals have a characteristic brilliance.

The flower is usually 4 to 5 inches in diameter when fully open, infrequently moreor less, petals average around 28, frequently some smaller petals and petaloids in the center, variable in number. I i

The flower opens high centered, informal, recurled, showing stamens and pistils gradually. The petals are variable from obovate to ovate to irregular and frequently with surfaces variously warped and edges especially of the smaller petals frequentlynotably irregular. The larger petals often have two notches, one each=side of a short apex that varies from acute to circular.

Texturev is medium to thick and leathery; both sides satiny; with slight veining which is not prominent. The time of opening in favorable conditions is two to four days.

The petals are substantial and after about five to six days drop off cleanly, except that occasionally one or two inner petals or petaloids cling to turn dull, to fall later.

ball in wet weather. The flower lasts well, is

The flower does not not affected at any stage by moderate cold or hot.

.Hips frequently develop to ovoid to globular,

color comparable with under side of leaves with variable colored overlay on the side exposed to the sun, moderately smooth; walls, thin, fleshy. Sepals are persistent and break off easily. Seeds variable in number; germination to date about 10% over a variable period.

PLANT Foliage.ls abundant, of compound leaves of three to five leaflets near the flower, five leaflets lower down the stem and frequently seven leaflets nearer the base. Size of leafletsmedium to small, averaging in size a little larger than half way between the average hybrid tea and the Rom wichuraiana leaflets. As the plants develop in size some of the leaflets develop to twice the size described above. Form of leaflets usually ovate with apex moderately acute, base rounded frequently slightly acute, in some instances with the circumference on one side of the petiolules form moderately pointed, frequently with one or out of alignment with the other side by about one-sixteenth of an inch, margins with fine "pointed serrations, petiolules short.

Color of leaflets on the upper surface is slight- -*1-y variable from Dark Dull Yellow Green, with reverse side nearly Asphodel Green overlaid with Dahlia Carmine. The young growth more nearlycompar'es on both sides with the color of the under sides of the leaflets, with edgesand 'midf ribs nearly Indian Red.

The rachises are medium, moderately narr ow to slender,' upper side smooth except some very 4 short hairs on edges. Under side moderatelysmooth, usually 3 to 5 short prick les. I

Stipules are medium to long, averagings light- 1y over three-quarters of an inch long, with sharp points, the upper edges of which normally form an angle of about 60 degrees.

Disease.This rose variety is more free from premature defoliation on account of black-spot and mildew than ismostany otherhybrid tea variety known to me.

Growth.-Habit, dwarf, becoming bushy to tall; somewhat spreading, later compact, more cumulative in growth from year to year than the normal hybrid tea-rose plant, bystems-or canes from=the base and by rebranching and growth and enlargement and extension ofthe stems. The growth is moderately free'at first,

developing more rapidly after one or two years under favorable vegetative opportunity.

Color of mature stems is the same as that of the upper surface of mature leaves, shading variously lighter and also with overlayof Indian Red variable in intensity. 5 Prickles, several,

inch, shading from Dahlia Carmine to lighter at the base, turning lighter throughout andlater to nearly colorless. Hairs few on upper portions of stems. 7 Color of prickles shading to color. of

times that"v of the commerce. a

c'omparisonsr-Probably the best known rose frequently two 'tawen' leaves,- averaging in 'length about one-quarter in commerce comparable with this new variety is the hybrid tea President Herbert Hoover, which has much the same color tones although more segregated; while in this new variety the colors are more blended. In form this new variety is more informal and the fragrance is more spicy. It can be grown to bloom more flowers, more constantly. The plant is more cumulative in growth from year to year, can be grown into a larger plant. The foliage averages smaller and more abundant, frequently with two more leaflets forming the leaves. Under the same exposure to black-spot this new variety is more free from premature defoliation without control. It can survive after exposure to colder temperatures, to flower normally thereafter.

I claim:

The rose variety substantially as shown and described, characterized by its new and distinct constitution, including resistance to winter injury, its intensity and continuity of florescence, its long keeping character of the color of its petals and the form of its petals and the form of the flower, variable within certain definite limits, its color varying from'vermillion, flame, to peach and coral, overlaid with nasturtium, all in association with its habit of branching from bloom stems and from the base and blooming in hybrid tea manner, and its degree of freedom from premature defoliation by black-spot during the growing season.
