ROSE

Josephine I). Brownell, Little Compton, R. I.

Application December 22, 1941, Serial No. 424,015

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 wz'churaioma hybrid tea, produced by meand 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 wichuraiana, of hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States.

The yellow to 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 deflnite 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;

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

And especially its characteristic of partial free dom 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. I

My new rose is otherwise described as follows,

ESSENTIAL INFORMATION Type: Hybrid tea, Rosa wichu'raz'ana hybrid, dwarf to ascending to tall to climber, forgarden display, cut flower and forcing or growing under glass. Class: Hybrid tea crossed with Rosa wichuraiana,

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 borne on a plant of the variety Golden Glow a hardy climbing rose produced by me and under my direction, and the pollen parent of this new rose was the variety Condesa de Sastago.

The pollenation that fertilized the seed that grew into this new rose, as well as the pollenation that produced one of its parents was directed by me and was performed by emasculating flowers and placing thereon a bag protecting them 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, 1937*. The seed was planted under my direction on December 11, 1937, and the date of the first flower was July 10, 1938.

The plant and flower seemed 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 1938-41 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 borne: Often one to two or three and frequently more on each stem, in the usual hybrid tea type of cluster. The pedicels and peduncles are medium in diameter and length, nearly 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 notably stiff and rigid. The angle at which the stems seek to grow is about 15 degrees from the gravitational influence.

further restricted by originator to include only Quantity of bloom! e '60 abundant, being those varieties that can survive moderately low sub-zero temperatures.

cumulative in quantity from year to year as h s and other dates herein are approximate,

Fragrance: Mild, distinctive, pleasing China tea in combination with that of Rosa wichuraiana 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 inhave one notch sometimes two and some have a small pointed apex forming a center tip.

Texture is medium to thick and leathery both sides satiny; with slight almost invisible veining. 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 1 1 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 humidity or wet weather.

' by moderate cold or hot temperatures, or by SepaZs.Persistent and break off easily after maturity. Seeds-Variable in number.

Plant Foliage: Is abundant, of compound leaves of three to live leaflets near the flower, five leaflets lower down the stems and frequently seven leaflets nearer the base. Size of leaflets metense and the form of the petals is less redium, av i i size about as l r as 1 the average hybrid tea leaflets.

Growth:-Habit is hybrid tea type of growth to ascending by branching and growth from the base, with some lateral stems that frequently bear smaller flowers than the terminal blooms.

Winter resistance1-From tests at Little Compton, Rhode Island this new rose plant compares in winter resistance with that of the subzero hybrid tea Pink Princess.

Comparisons:-I know of no Rosa wtchuraiana hybrid tea that compares with this new rose. Stargold open more star shaped, and is more nearly self in color. The bush of Stargold grows more upright and does not rebloom with Reproductive organs: such constancy through the growing season.
