ATTORNEY Patented June 7, 1949 Plant Pat. 846

UNITED STATES PATENT OFFICE 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 wichuraiana hybrid tea, 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 characteristics and especially as to their joint association with the characteristics inherited from Rosa wicharaiana, oi hardiness, or immunity from serious injury on account of cold temperatures prevailing in certain parts of the northern United States.

The red shades (ordinary dictionary defininite 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, notably after early bloom time and until frost;

The intensity of its remcntant and everbloom- Id ing 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 leaf leted leaves; which character seldom has obtained on hybrid teas not having Rosa wichuraiana ancestry, but frequently obtains on flower stems of descendants of Rosa wichuraiana 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: I

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 '7, 1944 The seed was planted under my direction on December 21, 1944, and the date of the first flower was July 8, 1945.

The plant and flower seemed to be of unusual meritand I have since made and directed extensive propagations and tests thereof.

Plants of this variety buclded from this seedling onto Rosa maltiflora 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 1944-45 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 stiif and rigid. The angle at which the stems seek to grow is about 20 degrees from the gravitational influen-ce.

Quantity of bloom: Free to abundant, being cumulative in quantity from year to year as the plant increases in size, notably free flowering through the summer.

Fragrance: The fragrance of my new rose is an outstanding and distinctive characteristic, under certain environmental conditions it is comparable with the sweet fragrance of certain carnations, and under other conditions, the fragrance suggests that of sweet spices.

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 1 This and other dates herein are approximate.
