Aug. 5, 1969 D. L- ARMSTRONG ROSE PLANT Filed Dec. 13, 1967 Plant Pat. 2,914

United StatesPatent Oflice Plant Fat. 2,914

Patented Aug. 5, 1969 The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the rose variety known as Helen Traubcl (Plant Patent No. 1,028) with the rose variety known as Manitou" (unpatented), the former being the seed parent and the latter being the pollen parent.

The new variety resulted from an extensive breeding program conducted by me with the objective of producing improved hybrid tea rose varieties which bear flowers 1D the pink blend to red color range, and particularly combining with such flowers color the flower size and form of the two parent varieties aforementioned, along with the greater flower pctalage and attractive plant habit of Manitou and the vigor of Helen Trau'oel. This new variety is one which achieves the aforementioned objective, as evidenced by the following unique combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(1) A vigorous plant having an attractive, uprightspreading, well-branched habit;

(2) Attractive, medium to large, semi-glossy foliage;

(3) A habit of usually bearing the flowers on medium to long, single stems of good strength;

(4) Double fiowers of medium to large size, with an attractive urn-shaped bud form approaching that of the parent varieties, and with the open flowers being fullpetaled and graceful;

(5) A distinctive and attractive light to medium pink blend flower color ranging between Azalea Pink and Carmine Rose, with some tinges of light yellow, particularly on the reverse side of the petals; and

(6) A strong flower fragrance.

In comparison with its seed parent, Helen Traubel, the new variety has a more compact plant habit, more flower petals, and a darker flower color tending more toward Carimne Rose than the flower color of this parent.

As compared with its pollen parent, Manitouf which has a vigorous, bushy plant habit, with large, glossy foliage; flowers generally borne singly on strong stems of medium length, with the flowers being quite double in petalage and light to medium red in color and being particularly notable for its large flower size and attractive and graceful open-flower form, the new variety differs from this parent by bearing somewhat smaller flowers, more flower fragrance and a light pink blend flower color in tead of the red flower color of this parent.

Asexual repoduction of my new variety by budding, as performed at Ontario, Calif., shows that. the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of. the vegetative growth and flowers of my new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
